GA.png Non-Canon: REMINDER! This page is considered as among one of the many pure game contents found exclusive in Mass for the Dead only. It includes the new standalone characters that had a first-time appearance in the game. Meanwhile, the old characters had a different role and fate than from the main storyline in the official books. For that reason, it has no connections to the canon story materials of Overlord Light Novel series. The content that you had read here are based on the Overlord mobile game.

Slimeko (スライム子) is a newly-designed virtual character created specifically to host the Overlord (Anime) and Mass for the Dead official channel.


Slimeko is actually a pink oozing slime molded in a top hat. By pulling her inside out and shaping it, she can mimic the form of a human girl. When using this facsimile, it resembles a young pink-haired girl that wears black gloves, a belt with a skull, and a corset dress. Slimeko's actual body lies on its head as a peculiar top hat. Strangely, her fake body's face is emotionless, though her actually body if closely watched, stretches, and quivers in reaction.


Despite her lack of emotion, Slimeko has a cheery personality. She appears to have no racial attachments to other slimes outside of Nazarick, seeing them as below her. Additionally, she is somewhat of a glutton as she likes to sample a variety of delicacies she comes across, be it cooked food or a rotting corpse.


Slimeko, though possessing a visage of a human girl, is actually a slime that can change a portion of her body to look human while her true form resides on top of the girl’s head. Disguised as a top hat, she controls her host like a puppet.


Mass for the Dead Arc[]

Main article: Mass for the Dead Arc

A slime Mercenary NPC that was summoned using YGGDRASIL gold coins by Momonga to help the main character of the game investigate the surroundings outside the Great Tomb of Nazarick after the Mirror of Remote Viewing detected a human village that was attacked by Chaos Beasts. Locating a survivor, Momonga dispatched the homunculus protagonist and Narberal Gamma to find survivors and interact with them. The slime assisted the duo in exploring outside Nazarick after the [Gate] transport was affected by the close vicinity of a Rift, throwing them off course and helped to detect various foes such as wild slimes. She eventually adopted the name Slimeko for convenience sake, which was a dead giveaway for her race and decided to use the alias Surako while in public. After encountering a pack of rabid wolves, she was protected by Narberal Gamma. To conserve energy needed for delivering [Message]s Slimeko took the opportunity to feed on the wolves corpses. After it became apparent they were about to meet humans soon, Slimeko then assumed a more humanoid appearance to better blend in with human society.

She and her comrades soon encountered the Swords of Darkness and Nemu Emmot on their mission to reach Carne Village and save its inhabitants. The NPCs from Nazarick soon attached themselves to the adventurers. Slimeko watched from the side-lines often protecting Nemu. When the group finally reached the village they had to defend it from marauding goblins.

Later when they reached the shelter containing the survivors from the village, Slimeko comforted Nemu when she learned that her sister Enri might be dead as she and another villager led some of the monsters back into the forest. Once the Sunlight Scripture arrived to watch over the villagers she and her comrades joined the adventurers in finding Enri. However, all they could find was a severed arm and brought it back to the village. Slimeko continued to work with the protagonist and Narberal. While the villagers were evacuated by the Swords of Darkness, the trio remained with the Scripture to investigate clues on the Cracks. She was present when her comrades joined forces with the Theocracy in battling the Chaos Beasts and even helped to kill a Giant Chaos Beast when it went after the refugees.[1]

After regrouping with the Sunlight Scripture, Narberal had departed to return to Nazarick. Slimeko then acted as a relay to deliver a report to Momonga on the protagonist's progress. They were joined by the dark elf twins Mare Bello Fiore and Aura Bella Fiora to help them in the investigation. She and the protagonist managed to convince the commander of the Scripture, Ian Als Heim to convince his men to cooperate with the elves despite their prejudices. When the group managed to enter the forest, they had a run in with the Wise King of the Forest. It attacked them with mental magic enchanting Slimeko due to her weak vulnerability. After the beast was beaten by Aura she made it her pet, and forced her, now named Hamsuke, to guide them to the Crack.[2]

Slimeko was present when the expedition reached their destination and found it to be a well spring of Chaos Beasts. Their party was overwhelmed by the miasma and the Chaos Beasts, forcing them to retreat. While Slimeko's group fare better than the Sunlight Scripture, there were still too man to defeat on their own. It was then they were rescued by Leinas Rockbruise and her imperial knights sent from E-Rantel. Together with the knights, they fought the Chaos Beasts and defeated the boss, learning that once all the Chaos Beasts in the area were defeated the miasma from the Cracks would cease.[3]

On a brief return to Nazarick, Slimeko retired to Ashurbanipal to help the protagonist organize the books on the shelves. They encountered Momonga, who was acting more expressive than usual. To her shock the protagonist guesses that it is actually Pandora's Actor impersonating the Overlord of Nazarick.[4]

Slimeko would accompany the protagonist and Ian to the city of E-Rantel, where they were greeted by Saint Clementine. Though she and the homunculus were warned about her by Ian, the two were escorted by her to register as adventurers at the Adventurer's Guild. They came across a new adventurer named Soi arguing with the receptions to be be granted permission to be granted a higher rank job. The adventurer became greatly annoyed after her complaints to assist Clementine were ignored. After word had been received about the protagonist's strength from the surviving refugees of Carne Village, Clementine used her authority to allow a promotion exam to take place for the chance for the protagonist to rise in rank. Soi hearing this also demanded the same and the two agents of Nazarick were forced to partner with her as they fought against several adventurers of incremental rank. The trio having beaten adventurers all the way to platinum were offered a chance to be promoted to that rank, but instead the protagonist declined preferring to earn the rank through the system rather than promotion. Soi then took the opportunity to join the protagonist and Slimeko's party much to the latter's chagrin.

However after the three were in private Soi revealed her identity as Solution Epsilon, one of the Pleiades who had been sent to infiltrate the city in advance. The revelation shocked Slimeko but she was thrilled at meeting her idol and bonded with Solution. Later the trio took on their first mission to examine the sewers of E-Rantel and report the status of the sanitary slimes there. Slimeko's knowledge on slimes proved invaluable as she and her team discovered that the slimes had underwent some mutation becoming more aggressive and hungry. After killing all the slimes in the area, they return back to the guild with the samples. There they make an acquaintance with Sophie Noia, a slime eccentric which causes Slimeko to become uncomfortable around her.

On their next mission, the three adventurers head to a quarry to provide security. To their surprise, they find Sebas Tian working there, having infiltrated E-Rantel before the hero's initiation as an adventurer. Subsequently, he became something of a leader among the refugees due to his kindness and charisma. Its learned that Sebas Tian had been trying his best to protect the humans at the quarry from the Stone Eater raids, however Soi points out that his actions might lead to drawing unwanted attention to himself. In order to make the miners less dependent on his strength, the group help Sebas Tian place himself in a situation where he was seemingly injured by the demi-humans. The act was enough to convince Sebas Tian's loyal comrades to come to his aid and drive the monsters out of the camp. Later after the trio returned back to E-Rantel with a shipment of rocks for the wall, they went to the Sunlight Scripture base where Ian introduced them to Nigun Grid Luin. Nigun was unconvinced by the hero's strength and wanted to test him, demanding the adventurer to spar with him. Slimeko witnessed her partner fight against Nigun, enough for the senior priest to admit the hero's strength. After the three finished their business with the Theocracy, the three returned to the inn where the homunculus retired to sleep.[5]

On the instances back in Nazarick, Slimeko and the protagonist partook in an expedition to locate the Legendary Tree at Albedo's orders to host a cherry blossom viewing for Momonga.[6] At the time she also was introduced to Neuronist Painkill when the torturer came looking for the protagonist at the library. The three soon became good friends as they sat down for tea to discuss their information gathering techniques and made plans to dine next time when they were free.[7]

When the Re-Estize Kingdom was attempting to reclaim an abandoned mine near E-Rantel, Slimeko and her partner ingratiated themselves with Blue Roses who was leading the adventurers sent out to eliminate the monsters infesting the mine. Unknown to the adventurers the mine was being operated by Nazarick to acquire the iron ores within. The undercover adventurers joined the adventurers expedition to monitor their progress as hopefully relay information back to Demiurge. Their information provided the Floor Guardian and his minion Abyss Demon vital information to make adjustments to their plans to turn the dungeon into an unappealing place and drive the adventurers away.[8]

Soi and Slimeko's fame eventually rose with the protagonist's deeds. The feat of their rise to prominence pleased Slimeko as soon they would be promoted to platinum rank. The next job they took was at the E-Rantel's Cemetery, though Slimeko detested it as she believed it was just a common task. However when they are doing the assignment, Slimeko notes to her companions on the large number of undead despite only being on the edge of the graveyard. Later after finishing the job, they receive a new request from Lizzie Bareare from the Pharmacist's Guild to acquire herbs from the Great Forest of Tob. In addition she asks them to do a personal task for her, to retrieve some items of her grandson's dead childhood. When its revealed that the items they are retrieving belonged to Enri Emmot, Slimeko realizes that Lizzie was Nemu Emmot's new guardian. The three adventurers take the job as it would allow them to maintain an association with the famed pharmacist. Their first destination being the forest, the adventurers reunite with Hamsuke who later proceeded to guide them to the spot where herbs are grown. After they collected the herbs, the party separated from the Wise King and then headed to the ruins of Carne Village. There at the village, Slimeko is disheartened by the destruction as it reminds her of the state of Nazarick. At a ruined home, Slimeko used her abilities to search through the debris and eventually found the personal effects of Enri Emmot. Upon their return to the city Slimeko gave the items to Lizzie, who hoped that they would be enough to help mend her grandson's ailing heart.

The next quest brings them close to the vicinity of the Katze Plains. Under a request of the imperial garrison, Slimeko and the protagonist reunite with Leinas Rockbruise to help her and her colleague Nimble Arc Dale Anoch escort supplies from Vadis Free City to E-Rantel. During the journey with a convoy back to the fortress city, the imperials and Nazarick agents run into various threats like Skeletal Dragons and a Death Knight. Slimeko's team's help was immeasurable to the imperials who offered the group a place within the Empire if they decided to join them.

Upon returning to their inn room, the trio start reviewing their accomplishments, when they have an unexpected guest: Saint Clementine. The holy woman then invites them to come to the mayor's residence to discuss a matter of importance. After she leaves, Soi and Slimeko become worried that their duplicity has been discovered. The protagonist calms the two stating to them that they should not panic as they should act accordingly. There, they are brought before various important figures of the city. The topic of the meeting, concerns the findings on the slimes that the protagonist and his team brought back to Sophia Noia. It appeared that the slimes were given high concentrations of alchemical solution, hence explaining the cause of their rapid mutation. Of the main suspect for this is a woman named Hilma Cygnaeus, a high ranking member of the Pharmacist's Guild but also a former member of the notorious criminal syndicate, Eight Fingers. Due to her dubious past and her current position in the Pharmacist's Guild, she was considered to be a culprit who is possibly responsible for the slimes' growth and mutation. The only way for the alchemical solution to have gotten to the slimes was if a member of the guild was poaching the supplies, making her suspect despite Hilma's pleading that she is innocent. Lakyus Alvein Dale Aindra, leading as the accuser for this case, notes that the alchemical solution could only have come from a supply of herbs, which the protagonist and his team recently provided to the guild. The accusation causes the three adventurers to become culpable to Hilma's crime. The three worried that they are under intense scrutiny, are vouched for by Saint Clementine as the protagonist reputation is well known in the Adventurer's Guild and could not be part of such a nefarious scheme. Upon further investigation into the facts of the case, the protagonist and Soi manage to prove Hilma's innocence and their own by pointing out that no record of any stolen solutions were made by the Pharmacist's Guild. Furthermore, it is discovered that the alchemical solution in the slimes that lived in the sewers originated from runoff water from a nearby herb cultivation plot nearby the treatment plant. In sort terms, it is a freak accident that was accumulated over the course of years and worsened due to the larger scale of herb cultivation.

Though the trio proved their innocence in the incident, it left an unresolved problem that a breed of mutant slimes were growing in the sewers. To show their loyalty to the city, the protagonist volunteers to have his team clear the sewers of the slimes as they know the terrain due to a previous expedition. Slimeko and her team then arrive at the sewage treatment plan with the key to open the gates. There, they are met up with by Sebas Tian who came at Saint Clementine's request. To draw the slimes out in the open, Slimeko is selected to be bait. Sitting out in the open, her presence draws the mutants out of hiding. Before the slimes could touch her, all three of her companions swiftly eliminate them. Despite the experience being too close for comfort, she enjoyed being useful and the thrill. The party soon discover a nasty surprise when they encountered a bloated giant slime that had feed off the waste in the water tank. The slime proves to be difficult to handle, as it has regenerative qualities, but Soi using her own acidic slime manages to eat the thing down until its core remains. Briefly admiring her idol's acidity, Slimeko then retrieves the slime core to show as proof of their kill to the city representatives.[9]

Slimeko chaperoned some visitors from another world and interacted with them in the Great Forest of Tob so that the magic caster among the visitors could display her explosion magic. The leader of the group attempted to flirt with her, though he was off put by the fact that she was really a slime.[10] She was later sent out on another mission this time through a [Gate] with the protagonist and the Pleiades. On the other side of the magic spell, there was a Mysterious Island that was believed to have signs of human habitation based on a map brought back by a skeleton summon. While enjoying the seaside view and gorging herself on defeated corpses of Giant Crustaceans, the party found a hidden pirate base that was destroyed by a Giant Mollusk. After defeating the creature, which Slimeko ate the remains, the explorers scavenged the pirate wreck for any valuables. Slimeko retrieved what appeared to be a treasure chest but was disappointed that it was empty. Her colleagues though told her not be discouraged as there was plenty of treasure that they could bring back to Momonga.[11]

Upon returning to Nazarick, Slimeko and her comrades give their report to Momonga who welcomes them back. The Overlord having been kept in the dark of their progress, praises their success in gathering so much information and flawlessly infiltrating the city without suspicion. For their efforts, Momonga believes that a reward is in order for each of them. Though they try to politely refuse, they give into his insistence. Once the formalities are out of the way, Slimeko watches as the protagonist informs Momonga about his invitation from Lakyus to meet Princess Renner. While wary of the risks of meeting such a high profile character so soon, his master in the end, accepts the protagonist consul to move forward with the meeting. Once the meeting is over, Demiurge takes the protagonist and Slimeko aside to share his thoughts on Momonga's non-committal statement of building a new system of their own rather than skulking in the shadows of a nation. From this, Demiurge tells his two juniors that he believes it to be their master's intention to pursue the goal of controlling all the neighboring nations to give themselves more freedom. With that, Demiurge directs the protagonist and Slimeko on their first mission in this great endeavor.

Together with the protagonist and Soi, Slimeko under her alias Surako meet the princess at Ro-Lente Castle in the Royal Capital. There, the team are contacted by the princess to be part of the security group for the Three Kingdoms' Conference of the Tripartite Alliance that will be hosted in E-Rantel. To prevent an international incident from happening, Renner gave the protagonist and his friends a new mission to embark on. This mission propose to the protagonist and his friends involved having to go and solve a string of strange disappearances among the refugees in the fortress city.

Once the team accept the job, they, Lakyus and Gagaran travel back to E-Rantel to solve the disappearances. There at the refugee quarter, they meet with the rest of Blue Roses: Tina, Tia and Evileye. Despite their search, the group have come up with no leads to the whereabouts of the missing people. To catch the culprits, a plan is enacted to make use of Surako as bait, whilst the others work in the shadows to monitor for signs of the enemy and trap them. Surako is disguised as a refugee using clothes donated from a pair of helpful civilians. The undercover adventurer proceeds to move through the alleys, under the watch of her assassin allies. Nothing seems to occur, passing by each assassin at designated locations, until after she walks past Soi who then detects someone to be approaching Surako. She alerts the others to the scene. Surako is soon about to be grabbed by three men in dark robes. but they are stopped by several gunshots aimed at their legs from a hidden cloaked figure on the rooftops. The distraction gives enough time for Soi to come and save the undercover slime. After the men uses Skeleton Warriors to buy them time to escape, they are lost by the adventurers momentarily. Soi though manages to locate a secret passageway in the alley, allowing of them to continue the chase. Two of the robed men who attempts to avoid being captured decided to commit suicide, but one of them is stopped by Soi. Blue Roses then takes the man into custody to be interrogated.

After Blue Roses departs, Surako thanks Soi for intervening in saving her from those men, however the undercover maid redirect her thanks to Shizu who reveals herself to have been shadowing the group after Soi called for reinforcements. The maid then departs wishing the group luck in their mission. Once the authorities had interrogated the man, it was determined that the culprits were members of Zurrernorn. It was believed that the cults was going to enact a ritual that could create powerful undead called Death Spiral. Their investigation eventually took them to the E-Rantel's Cemetery, where the adventurers split into three teams to cover more ground. The protagonist and his team now alone, enabled Shizu to come out of hiding to aid them. An increase in the rise of undead was seen east in the graveyard where the adventurers regrouped and found a secret entrance to mausoleum. There, they end up encountering resistance in the form of Six Arms, who were once members of Eight Fingers, now turned mercenaries were working for Zurrernorn in their plans. The adventurers managed to kill an Executive of the cultists as well as one of Six Arms. Nearly all of the members of Six Arms are captured, save for Zero who managed to escape being a threat at large. With Zero still a possible threat out there, Princess Renner places the duty of tracking him down and bringing him to justice falls to Blue Roses. To cover the Kingdom's security requirements for the upcoming summit meeting, the protagonist and his friends are asked to act as escorts for her family.[12]

During a quake that affected the mine in Nazarick's possession, Slimeko was party of the team sent to survey the new veins of ore that were discovered. She encountered the Abyss Demon who she was glad to see to have recovered from his battle with Blue Roses, well at least physically, mentally she was surprised that he had become quite traumatized by his near death experience.[13] When she returned to Nazarick, Slimeko was in the library cleaning the shelves with the protagonist. The two are sought by Mare and Aura when they show them a weird pumpkin. The thing turns out to be alive as it attacks the slime, but is quickly bashed by her friends. Not wanting it to go to waste, Slimeko ate the remains. An infestation of the pumpkins break out on the 6th Floor causing all of Nazarick to be on alert. Since eating the pumpkin, Slimeko began to experience internal discomfort and forcibly spits out the pumpkin that was still very much intact and alive. The pumpkin creatures prove to be impossible to kill, but the protagonist realizes what they actually are and hurries with Slimeko to retrieve costumes for Mare and Aura. After informing that they needed to carve and place candles in the monsters to exorcise them, Slimeko assisted in removing the other pumpkins around the dungeon.[14]

The slime would serve Nazarick acting as an observer to some new visitors from another world, this time a battalion of soldiers.[15] On another occasion, journey with the protagonist, Aura, and Cocytus to the Great Lake to assist a lizardman named Zaryusu Shasha to determine why the lake's temperature was rising. It was believed Caloric Stone was responsible and the team wished to claim the World Item for Nazarick, though it turned out to be Giant Lizards containing Heatstones to be the reason. Still the items were taken back to Nazarick as payment and the team part the lizardmen as allies.[16] At the initaion of the Nazarick Fighting Tournament, Slimeko used her skills as an orator to act as an announcer alongside the protagonist.[17]

To prepare a Nazarick hosted Christmas party, Slimeko was part of the group sent by Albedo to acquire a meat dish. Using their contacts in E-Rantel, the group determined that the best meat to use for their part was a peryton more specifically the famed Pure White Peryton. With the aid of Hamsuke the party hunted the elusive creature in the mountains and brought it carcass back to Nazarick for the feast.[18]

When Nazarick was affected by a strange "New Year's mood" that was affecting all the NPCs, Slimeko, the protagonist and Solution Epsilon were called back from E-Rantel by Momonga. The slime noted the strangeness of the inhabitants and why they seemed not to be concerned about the potential danger they were in. At the Takemikazuchi Shrine, playing along with the New Year's event Slimeko writes down her New Year's aspiration in calligraphy to be "Eating Faster". Slimeko would witness Momonga defeat Shiramochi-ō who was responsible for the New Year's event.[19] Unfortunately the death of Shiramochi-ō did not end and the White Mochi King created a time loop repeating the events of the New Year, with slight minor differences. In the new loop, Slimeko once again was recalled back to Nazarick by Momonga to solve the mystery of the New Year atmosphere in the dungeon. However a new character named Shiro was traveling with them and they had no idea on his identity. In her New Year's resolution, at Bishamonten Shrine Slimeko aspired to improve her acidity so that should could digest faster. Later she witnessed Shiro reveal himself to be Shiramochi-ō and fought Momonga. To the shock of Slimeko and her friends Shiramochi-ō chose to willingly die as he grew attached to the Nazarick denizens and was unwilling to hurt them. Before he allowed himself to be killed she watched him play his last game with Aura and Mare.[20]

To resolve the issue of the Queen War, Shalltear came to the protagonist and Slimeko to divine Momonga's intention. It was believed by Shalltear that Momonga's lack of a decision on the Queen War was a hidden test to prove herself worthy as being his bride. Thinking that was the case, Slimeko and the protagonist aided her in formulating a strategy to win the Overlord's heart through the "Trial of Love". The idea was almost successful as it did garner Momonga's attention, after Shalltear took her friends advice to play hard to get. But when she made her declaration of love to Momonga she was sadly informed them that there was no hidden challenge. Despite the failure Slimeko encouraged to try again next time to win their master's heart.[21]

Surako and her friends having accepted the job from the princess, chaperoned the royal family to the venue of the summit. Once there, she and comrades observe King Ramposa III's talks with Emperor Jircniv Rune Farlord El-Nix of the Baharuth Empire and Cardinal Raymond Zarg Lauransan of the Slane Theocracy on the state of the world since the emergence of the Cracks. While the situation with the Contaminated Beasts and Chaos Beasts have yet to be resolved, the nations agree that more investigations must be conducted to determine the cause of the phenomena. The revelation from the Theocracy brings intrigue to her and her comrades when Cardinal Raymond discloses that appearance of the Cracks and Chaos Beasts coincide with a cycle that happens when a new power appears in the world at regular intervals. Tensions flare between the heads of state of the Empire and the Kingdom on what direction the Alliance should take to handle the crisis. Eventually, a recess is called to pause the meeting to allow the representatives to rest. The escorts are relieved for the duration and have a brief encounter with Fluder Paradyne.

The meeting eventually resumes, and Slimeko and her friends continue to watch the proceedings. Emperor Jircniv continues to place his agenda before the Alliance, one being the implementation of a merit-based system to equally divide resources. This goes in opposition to King Ramposa's idealism as he fears that those unable to contribute will not afford to exist in the system by the Bloody Emperor. Jircniv is blunt on the reality of their situation that their resources are limited. If Ramposa III wants to protect his people, he then needs to get stronger people in the Kingdom to work. He recommends that the Kingdom bring forth all its able bodied people to contribute to the alliance and only then would he be satisfied. Gazef Stronoff taking a stand for his liege pledges that he swears that the troops of the Kingdom led by him will be the work of thousands. The emperor is skeptical on such a claim, but offers a chance to prove it, by having the escorts of the Kingdom and Empire show their abilities in a match.

Slimeko and her friends, alongside Gazef are placed in a series of mock duels against Nimble, Fluder, and to their surprise Zero who had gained diplomatic immunity in the Empire. Together with the Warrior Captain, Slimeko's adventurer team overcome each opponent with the final match including the protagonist Soi, and Gazef against Fluder Paradyne. The match is an intense one but the group manage to drive Fluder to the edge, until he immobilizes them with his [Triple Arts Magic] magic. His spell is cancelled by Enhela Read Gahi, who declares the match to be over as an emergency has occurred. It turns out that a group of Chaos Beasts and Contaminated Beasts have begun invading north of E-Rantel and broke through the imperial and Theocracy defense lines.

Seeing that the nations will need to devote a reasonable amount of forces to subjugate the monsters without leaving the city vulnerable, the protagonist volunteers his party to handle the monsters and help evacuate any surviving soldiers. Ramposa readily accepts the help and approves of the mission. The party then heads to the front lines where they, Nigun and what is left of his men just at the edge of the city, trying to reestablish a perimeter. Learning from him that Ian and Leinas remained behind at the battle lines to buy time for him and his men, the group quickly head to their last location. Outside the boundaries of the city, they are joined by both Shizu and Entoma Vasilissa Zeta who help them fight their way to the survivors. They make it in time to find survivors unconscious, but alive before a Chaos Beast that can use Martial Arts. The Nazarick agents battle and succeed in killing it, and with its death the leadership of the horde collapses saving the city and earning the Alliance's gratitude.[22]

Slimeko was part of an expedition led by Momonga to the Roble Holy Kingdom to investigate why it fell. The group journeyed to the Great Wall where they found the structure to be overrun by Chaos Beasts. The expedition found evidence that the forces at the wall were all killed by a powerful entity while doing training drills. The investigation took them to Kalinsha where Slimeko used the opportunity to taste the bodies to determine when the city was attacked and to slip under the debris to collect journals and maps. The expedition encountered a Dragon Chaos Beast which was eventually slayed and a strange artifact was brought back to Nazarick to be examined.[23]

Slimeko was with the protagonist during a meeting with Demiurge who asked the latter on a hypothetical question of what would happen to the Kingdom if it sent one of their best assets out in the field and never came back. He of course was using this to bring up the topic of Gazef Stronoff's disappearance which the protagonist stated he would make use of that situation to Nazarick's advantage. The two later returned to their high class inn in E-Rantel where Solution is at. They are interrupted when Prince Zanac Valleon Igana Ryle Vaiself appears and escorts them to his father. There, Slimeko and her friends learn about the reason of Gazef's disappearance and how he and his men were tracking the origin of the Chaos Beast horde that attacked the city. It was reported that he found a cave where they originated, but ever since exploring its depths they lost contact with the troop. The slime watches as the king implores the protagonist's aid, offering anything in return. The protagonist seeing an opportunity is at hand, requests Ramposa III to consider forming an alliance with the protagonist's nation and presents a formal letter that he wishes to be approved. If such an alliance were made then the protagonist's nation would approve of the latter's involvement of this mission that the Kingdom wishes for them to undertake. The Kingdom having no choice but to consider it, agree to the terms. The adventurers then head out to the location, and are met by Shalltear Bloodfallen who assumes the alias of Shall and an adamantite adventurer. Before setting out to Gazef's location, the group head to the Crack site in the Great Forest of Tob to practice a rescue operation as the poison is seen as an obstacle that might impede Gazef's safe return. After Shall discovers a method to safely dispel the poison fog, the group then depart from the forest to continue onward with their mission to retrieve Gazef, whether he is dead or alive.

The group arrives at the cave where the Warrior Troop was last seen and also reunite with Blue Roses who were also dispatched. However, it is being guarded by two powerful Chaos Beasts. Defeating them takes not only the combined efforts of Blue Roses and the protagonist's team, but also the intervention of Brain Unglaus, an old rival of the Warrior Captain.[24]

After the opponents are taken care of, the protagonist volunteer to head into the cave to search for Gazef and his men while the others guard the entrance. Going deeper, they discover the remains of what appears to be a base camp in the cave. However, it has been turned to rubble as the ceiling had collapsed on the soldiers and magic casters that were in charge of communication. Slimeko using her slime body determines that there are no survivors in the rumble. Using her senses of smell, Slimeko guides her companions following the trail of blood and bodies. Soon enough, they eventually come across a surviving soldier who remain alive. Slimeko attempts to approach him, but her companions quickly step in, narrowly missing being killed by two Stone Eaters that were using the body as bait. After defeating the demi-human tribe the group continue on, until they come into a vast cavern where a Crack has formed. But to their shock the entire area is covered in body, from wounds of a blade. As to who the perpetrator is, it is found that Gazef Stronoff is the only survivor and had succumbed to the poisons of the Crack which had ended up turning him into a feral monster. Shalltear then steps in to engage him. Slimeko and her friends watch as Shalltear fights Gazef tirelessly until he has exhausted himself of all his Martial Arts and is quickly subdued by Soi.

The group then discover that Gazef wasn't alone as a mysterious tentacle beast emerges out of the darkness and tries to take Gazef's body. The Nazarick agents prevent Gazef from being eaten and turn their attention on killing the new threat. They succeed in slaying the monster, which is then turned over to Nazarick for study while they transport Gazef back to E-Rantel.[25] Slimeko would observe a new batch of visitors from the Crack in the Throne Room, this time the situation devolved where one of the visitors fell into her dark persona and began attacking Nazarick and her own allies.[26] Due to her experience in locating the Legendary Tree, Slimeko and the protagonist joined Demiurge's latest quest to locate the Parent Tree for Momonga.[27]

Slimeko and the protagonist would be involved in a plot to have Albedo seduce Momonga. They secretly helped her make her move to arrange her to work as a maid and get close to the undead. The plot was expanded to get Momonga alone with Albedo using a security drill on the 9th Floor to lock the area down. The plot was caught wind by Solution who had some suspicions of something going on after she interrogated the protagonist and Slimeko. Unable to keep her silence to her senior, Slimeko spilled the plan to Solution. Solution then informed Shalltear of Albedo's plan causing the vampire to rush back to Nazarick from the mine near E-Rantel and save Momonga from Albedo forcing herself on him.[28]

The Redeem Slime would go on further missions, such as prospecting for a gold vein in the Azerlisia Mountains with the help of some visitors from another world.[29] And on a fact finding mission to determine if there was evidence of players in the New World. It led to a seaside village where a dwarf named Tsuibayaya was working in replicating swimsuits from the tales of Minotaur Sage.[30] And more close to E-Rantel, Slimeko helped to investigate the hauntings of the Tob Forests. Her team were reunited with the Swords of Darkness who were able to clarify that the Harvest Festival was necessary to appease the evil spirits of the land. Working with the Pleiades she helped to prepare a suitable festival only it to be crashed by the real culprit Kyuko. Once Kyuko was subdued, and misunderstandings were cleared up, Slimeko witnessed the fox join Nazarick voluntarily.[31]

When a new batch of visitors came, led by a hero and composed of a trio of goddesses, Slimeko acted as one of their guides to hunt food. This was in part due to the paranoid nature of the hero who did not accept the charity of Nazarick, believing the food served was drugged. Their hunt is interrupted by the appearance of the Grim Reaper who attacks them forcing Slimeko to flee with Narberal and the protagonist in the air.[32] After the visitors left and returned back to their world, her team stationed in E-Rantel would be called to investigate one of their own in Nazarick: Sebas Tian. It was believed by Solution that the butler was secretly meeting in E-Rantel with someone without clearance from Momonga. Slimeko was horrified by the accusations pertaining to Sebas Tian, and was had uncomfortable with the idea that her team was sent to spy on him. Slimeko was relieved to learn that Sebas Tian was not a traitor but doing his own independent investigation of the slave ring in the Black Market. The said investigation led to the protagonist's team in taking down Cocco Doll and capturing a New World demoness named Isabella.[33]

Silmeko would later attend a gathering in the Throne Room where Demiurge laid out Nazarick's plan of world domination. As a part of those plans, once her team returned to E-Rantel, they gained an audience with King Ramposa who wished to reward them for Gazef's safe return. It was there that she witnessed the protagonist negotiate to have the Re-Estize Kingdom turn administration over to his 'nation' in order to establish a system that could better handle the current state of the world. Though the royals were skeptical on the group's political affairs, they agreed to think on the matter to the protagonist. Once the meeting ended, Slimeko praised her partner on how easily he handled the royals. While they are discussing the meeting, Slimeko hears a familiar voice coming from an alley. She goes there to take a look followed by her companions, where they find Nemu being accosted by two men. Before they could intervene in the mugging, a strange pale faced boy wielding a staff approached the men. The men attempt to intimidate him only to be swiftly killed by his magic. Seeing Nemu's relieved face, the adventurers confirm that the girl knows the young man. They make themselves known to the girl, who happily greets the protagonist and Slimeko. Nemu then introduces them to Nfirea who turns out to be the grandson of one of their previous clients who asked them to collect things from Carne Village. It was here the young man asked them about Enri Emmot's fate. After Slimeko and the protagonist told him about how she died, Nfirea briefly exposed a face of anger towards the Chaos Beasts for their role in killing his friend. Having learned what he needed to know from both Slimeko and the protagonist, Nfirea then bids the group farewell as he leaves with Nemu. Slimeko having watched the young alchemist noted that he was unstable due to his cold-blooded reaction to killing the crooks, though the protagonist and Soi commented that he was interesting and should be kept a close eye on.[34]

After the hot spring facilities of Spa Resort Nazarick were fully repaired, Slimeko did some research in hot springs and activities so Momonga could use it to strengthen the bonds between him and his subordinates. In a dispute over the right to be Momonga's bathing attendant, Slimeko acted as a moderator for the Miyoshi Cup.[35] At the time of a second Christmas party in Nazarick, Slimeko and the protagonist helped to make preparations.[36] In an unusual event when some visitors from beyond the Crack returned to Nazarick, Slimeko was there to welcome them back. They brought a new face among them who had information on the future and the apparent destruction of Nazarick. Slimeko was part of the group that helped to ensure the future did not come to pass.[37]

While helping the protagonist move some books from the library to his residence in E-Rantel they met with Mare asking them about a phrase "in love". The events led to the creation of Project Valentine and the use of chocolate confections as diplomatic tools. A bake off was organized and Slimeko and the protagonist witness Albedo and Shalltear's renewed rivalry over the Queen War and interest in participating. Acting as a neutral party, Slimeko served as the moderator for the taste competition.[38] In a plan to improve mental heath of the people of E-Rantel, Nazarick served as a test bed for an idol plan with Shalltear and Aura taking the roles of Acidity and Alkaline and creating LittleMass. For the duration of the idol plan, Slimeko acted as their attendant, advising them when they were on break and also coordinating the handshake events.[39] When the idol group were about to split due to personal reasons, Slimeko became worried and was stunned that its end was premeditated by Demiurge to drive more attraction for the finale.[40]

Due to the success of the idol plan among the general maids, Momonga decided to apply it in E-Rantel in the form of an exchange tournament. Officially it was an event sponsored by the Re-Estize Kingdom and Sorcerer Kingdom to help recruit more adventurers and advertise chocolate trade item. In truth it was to gather information on the adventurers and their strengths and also create a opportunity to insert Shalltear and Kyuko as new undercover Nazarick agents as adventurers. The protagonist and Slimeko worked their end in E-Rantel to organize the event using their connections to have Blues Roses and even the Swords of Darkness participate.[41] At the start of the tournament, Slimeko under her alias as Surako acted as one of the announcers with Pluton Ainzach.[42]

While playing her role as Surako in E-Rantel, her adventurer team is paid a visit by Prince Zanac, wishing to hire their services to investigate a string of disappearing bride candidates happening in Marquis Blumrush's territory. Her team accepted the assignment after Zanac warned that if nothing was done not only the innocent will pay but his idiot brother might get involved and make things worse.

During the mission Surako worked with not just her team but Blue Roses to find if Blumrush was truly the guilty party. While observing Evileye refused to act as a bride candidate for the mission, she is shocked when Narberal uses her blunt words to convince Evileye to take the assignment as part of being professional. As part of the survey team she collected testimonies from the victims, include a worried father whose daughters were taken while in the noble's territory and who she pitied. The team got pulled into a separate mission which was assisting the city soldiers in exterminating undead that appeared in a nearby mine. The undead were not irrelevant to their original mission as they were being drawn to the mine due to Zurrernorn, who were using the brides as sacrifices. Her team reunited with Narberal and Evileye who still in their bridal gowns gave the slime the opportunity to admire their outfits. Surako would be surprised that Evil Lord Greed was at the mine, expecting AByss Demon instead, but his presence at the mine provided the smoking gun that would oust Blumrush as collaborating with not just a death cult but the Demon Emperor. After the mission was completed she and her team returned to Nazarick and were lauded for their work as their efforts helped to secure the mines around Re-Blumrushur for Nazarick's extraction.[43]

Slimeko was with the protagonist and Solution before Momonga and several members of the instigators of the demonic raid on E-Rantel. There, she witnessed Momonga praise each of the members of the operation for their success. Each members from Shalltear, Demiurge, and Pandora's Actor were granted a wish that was made true by Momonga. The protagonist who provided his identity and vocal chords for Pandora's Actor to use for the operation. Despite the pain of having his vocal chords removed via a Lip Bug, the homunculus believed it to be a small price. For his reward, she asked to be allowed to live outside of Nazarick. Though this wish was almost treasonous to separate from his master, the homunculus explained that it was out of practicality as he intended to take on the role to effectively manage E-Rantel city in preparation of Nazarick's eventual takeover of the Alliance. She was relieved that the protagonist's reasoning was accepted by Momonga who permitted. However, Albedo felt shocked of he and the rest for forcibly volunteering herself on a field mission with the protagonist to secure a treaty with the Alliance when they signed over E-Rantel's administration rights to Nazarick.

The three undercover adventurers later headed back to E-Rantel while they waited for Albedo to arrive for the summit of the Tripartite Alliance. Once they're there, Slimeko marveled at the amount of progress that had been made since the city and Alliance had followed the protagonist's leadership. From the completion of the Fourth Wall, expansion of the residence and agricultural fields, the integration of demi-humans into human society, all seemed to be leading towards the protagonist's ideal of creating the capital of the Alliance into an open city. After the trio helped assist in the distribution of rations to the people, they briefly met with Saint Clementine, who is now the elected administrator of the new city section. The three passed some words of congratulations to her before they were joined by Jugem who trained with the protagonist.

They eventually met up with Albedo now in regal attire as the Prime Minister of their nation, and escorted her to the summit venue. Slimeko and Soi nearly sweated nervously when Albedo was greeted casually by a passing ogre, but the situation did not escalate to violence as Albedo controlled herself, but not without subtly threatening the demi-human before the adventurers hurried her away. At the venue, they were greeted by Emperor Jircniv who Slimeko was shocked by his friendliness towards the protagonist and honest smile on his face. The emperor noticing her discomfort explained that after being saved by the protagonist when Jaldabaoth was about to execute him back then, he had begun a new lease on life ever since.

At the venue, Slimeko witnessed King Rampossa III and Emperor Jircniv formally acknowledge the protagonist and his deeds and cede the administration rights of the city to him and his nation. But it was not without objection from Enhela of the Theocracy who was worried about the potential of abuse of power. Though Albedo and the protagonist managed to assure the priest's fear, allowing the Theocracy to act as a deterrent to his nation's influence, which then lead to the Theocracy retracting its objection. Before long though, the Sorcerer Kingdom signed a treaty with the Tripartite Alliance for the city of E-Rantel, making it into an independent city for all and the protagonist was awarded the title of Territory Guardian of E-Rantel.

Slimeko and Soi then joined the protagonist in his duties, the first was to oversee the new E-Rantel Magic Research Institute. Though initially excited for the inspection, when she found the location to be located in the E-Rantel's Cemetery Slimeko's excitement waned due to the dark atmosphere and dangerous monsters contained within. Though Slimeko brightened up when she saw some of the floors dedicated to research such as on slimes and the purpose of why the institute was station in the graveyard. At the last level, she ends up expressing her own surprise from seeing Fluder's appearance there and his clinginess toward the protagonist, due in part to how the homunculus had secretly solicited the old man's help by revealing him Ashurbanipal and solidifying his cooperation with Nazarick.[44]

During the subjugation of the mind-controlled Shalltear Bloodfallen in the Katze Plains, Slimeko coordinated with the protagonist to command the army of summons against the vampire.[45] Later Slimeko in E-Rantel heard from Pluton Ainzach that the undead in the Katze Plains was decreasing, unaware that the region was now under the control of Nazarick. The Nazarick spies managed to attribute the decreased undead to the actions of Kralgra having sacrificed their lives and subdued the Captain of the Ghost Ship.

When she and her partner returned to Nazarick and briefed Momonga, Albedo and Demiurge on the movements of the Empire. So far it was learned that the members of Six Arms were conducting a undead elimination campaign through the plains, but not for money but to capture the elder lich in control of the Ghost Ship. After their spies reported that the workers were working for rebellious nobles, she wondered what prompted the nobles of the Empire to undermine the emperor. From her summoner Momonga she learns that the rumors of Emperor Jircniv's capture by the Demon Emperor Jaldabaoth has made him viewed as weak by the former aristocracy who see it as a sign to revolt and reclaim their power. It only made things more confusing as why Jircniv was not doing any actions to crush the opposition. Possibilities were thrown around that the emperor was truly traumatized by the demonic raid, acting or even unaware of the danger. Among these Momonga ordered the undercover adventurers to wait and see what would happen before committing any actions. She and the protagonist were to ensure that no one from the side of the Kingdom would interfere with Nazarick's operatives acting on the Empire's side.

The Slane Theocracy would notice the lessening numbers of undead at the borders of the Katze Plains and would sent Nigun and Ian to investigate. To make sure that the priests did not come across Six Arms in the plains, she and her team of Darkness acted as their guides. When they were deep enough in the plains, Slimeko secretly sent a [Message] to the Iguva=41, new elder lich in control of the Ghost Ship, to drop down a Death Knight as he passed them in the fog. The powerful undead was enough to convince the members of the Theocracy that the undead were not vanishing but merely hiding deeper in the plains.[46]

While researching in the library with the protagonist, the two unexpectedly met with Momonga. Since he was present, the Overlord offered to assist the protagonist in clarifying any cultural knowledge that he did not know. The protagonist then showed Momonga a unfinished work which the undead stated was just a piece written by one of his comrades. After reading it, though the contents gave Momonga an idea to host a Tsukimi. Slimeko and her team were outside the dungeon when they were called to attend the festivities back at Nazarick. En-route to the dungeon, night had spontaneously changed back to noon. To get to the bottom of this phenomenon, Slimeko and her team once again returned back to E-Rantel to gather information first from speaking with the Sword of Darkness at the Adventurer's Guild and then attending an emergency meeting with the guildmaster. At the meeting Blue Roses was present, though strangely Lakyus and Evileye were wearing revealing bunny girl outfits. The slime was the first to ask why they were in such clothes, but the adventurers did not seen bemused by their state of dress and so the meeting continued.

Once the meeting was over, Slimeko used her magic to send a [Message] to Momonga. Acting as a relay she learned that the protagonist had figured out that the work he found in the library was actually a prophecy made by one of the Supreme Beings, with references exactly pertaining to the current situation. And suspected that the members of Blue Roses were the invaders from the moon mentioned in the prophecy. To confirm their suspicions she and her team went to Renner to ask what Blue Roses had been doing lately. But the princess was unable to tell them anything as Lakyus was very time lipped on her team's next assignment. Slimeko believed that they could inquire the guild of what Blue Roses was up to, but the information was confidential per guild rules. The protagonist had Slimeko get in touch with Demiurge so that he could go over the contents of the prophecy to seem what the future may hold.

Slimeko's team would approach Blue Roses out in the field when they were supposedly investigating the cause of the daytime. They offered the female adventurers sake to drink. The members of Blue Roses were proven to be imposters after they failed a test by Soi who claimed that the drink was a potion that affected undead which they responded that they were despite supposedly being human. Now with undeniably proof that these people were not their allies, Slimeko and her team, who was also joined by Narberal faced off against the fakes. The fakes eventually dropped their disguises revealing themselves to be a sort of slime that Slimeko never seen before. Defeated the heteromorphs explained that they were survivors an attack by Chaos Beasts that drove them from their home. Having come to the region of the Kingdom, the five heteromorphs by chance sighted Blue Roses training nearby and copied their appearances using their abilities to blend in with the locals. The daytime was in fact caused by their Fake Sun to prevent them their affliction of turning into mindless beasts. After their story was finished, Slimeko and her team decided to bring the five refugees back to Nazarick as new recruits. Once the phenomenon was solved, the slime was later seen enjoying dango at the reinitiated Tsukimi.[47]

Slimeko and her partner the protagonist would return to the library to find Shalltear and Albedo researching on the Halloween Festival. It was then she and the protagonist brought the issue of the popularity of chocolate in E-Rantel since its debut during the adventurer exhibition and how it was destabilizing the Adventurer's Guild's position. In order to supply the demand for the confection, the three arranged to create a new cheap mass produced type of chocolate for the citizens of E-Rantel. After it was agreed, she and the protagonist went back to E-Rantel to tell Pluton Ainzach of the plans of the Sorcerer Kingdom to develop the sweet and allow the guild to be in charge of its distribute for a small profit in return. Once that task was completed she and her partner returned to Nazarick in time for the banquet of the Halloween Festival on the 6th Floor.[48]

Slimeko would join the protagonist's round to check on the status at the E-Rantel Magic Research Institute there she and her comrades were shocked that the researchers may have found a method to cure the contamination. Afterwards Slimeko and her friends met with the royals of the Kingdom, where the protagonist informs the king that he will be away to open trade relations with the Dwarf Kingdom. Once they left, Slimeko and the homunculus parted ways with Soi who was assigned to stay and guard the institute. Slimeko would be part of the expedition that would travel to the Dwarf Kingdom. Before going she and the party members attended some checks on Hamsuke and Fake Nazarick and also picking up Zenberu as a guide. Though the lizardman was able to guide them to the general area they were unable to locate the cave to the underground city. The slime was able to find it by accident after falling into the snow, uncovering the cave. The city though was abandoned and Slimeko was able to sense blood in the nearby mines, leading the expedition to finding Giant Lizards and also a dwarf named Bigosa. The dwarf was convinced to guide to the other dwarven city of Feo Jera but the group were shocked to find that they were too late as the Giant Lizards had already destroyed the city and the dwarves had fled. Through the rubble, Slimeko was able to find a survivor who told the party that the dwarves had fled to Feo Berkana to seek the protection of the Frost Dragons. The group got there just as the Giant Lizards were attacking the city. Slimeko and the others hurried to interrupt a meeting between the Regency Council and the ruling dragon. After the dragon was defeated by Cocytus and convinced to join in an alliance with the dwarves and the Sorcerer Kingdom, Slimeko and the protagonist were escorted back to E-Rantel by Yuri and CZ. However when they returned to the outskirts of the city she and her partner found that two armies of the Re-Estize Kingdom were facing each other.[49]
