Protagonist (Mass for the Dead)

Protagonist (主人公) is a homunculus NPC created by the Supreme Beings and the player playing the Mass for the Dead game.

Appearance
No clear details are given on the protagonist's physical description and looks in the initial start of the game. It is only until later is the character portrayed as wearing a full suit of jet-black armor with a red mantle as part of his "Dark Warrior" identity which is played by Pandora's Actor. Though the protagonist mostly discards the armor to maintain a low profile when in the field.

Personality
Despite being one of the least known NPCs in Nazarick, the protagonist is just as loyal to the Supreme Beings as any of the Floor Guardians and Area Guardians. Due to the knowledge he acquired from the library, the protagonist is no doubt one of the most intelligent of the NPCs. After his existence was made known to the rest of the dungeon, several of the denizens of Nazarick would go to him for assistance in research.

Due to his life in obscurity, and his lack of a definite role given to him by his creator, the protagonist is eager to prove himself as a valued subject of Nazarick as he believes that it will provide meaning to his life. Unlike the NPCs of Nazarick, such as Demiurge, he is friendly to humans and is behaves quite like a human. The only time the homunculus expressed any cruelty was when he encountered a cannibalistic demon.

However, as common for someone of Nazarick, he has a personality that won't make him hesitate to use humans. Though he does not dare to maintain relationships with people who are unnecessary for Nazarick's reconstruction, such as the Swords of Darkness. His loyalty to to Nazarick is undeniable, and is willing to offer his own flesh in service.

Background
A homunculus that was created by one of the Supreme Beings and situated in Ashurbanipal. The protagonist has never been appointed a true position in the dungeon. Before the Great Tomb of Nazarick moved to another world, he busied himself in continuing to learn the wisdom of his predecessors by reading the collections of the great library to help the Supreme Beings someday.

Mass for the Dead Arc
The protagonist awakens to consciousness, finding himself in a ruined library of Nazarick. Confused on what transpired, the homunculus rushes outside to find out what is going on. To his shock, he comes to the Lemegeton to find all of its golems shattered and its countermeasures destroyed. Seeing the unthinkable, the homunculus assumes that an enemy raid has occurred on the 10th Floor. Afraid that he is alone, the protagonist hears sounds coming from the Throne Room. He then rushes there to see if there are any survivors. The homunculus has a chance meeting with Momonga who upon spotting him questions him on his identity. The protagonist quickly gives the Overlord his identification as one of his friends' creations, which confuses Momonga due to the former's speech and calling for a GM Call. Aside from that, Momonga is skeptical whether the homunculus is an NPC as he never has seen him before in the tomb and thinks he an enemy pretending to be an NPC that somehow survived.

Momonga then demands the protagonist to tell him what is going on, but even the homunculus is unsure of the situation or what his master is talking about. One of the nearby Pleiades maids however vouches for the identity of the protagonist, after they have been successfully resurrected. Though none can provide any answers to how they died or what has happened. They are interrupted when the anomaly, a Crack, where the Throne of Kings once stood begins to flicker when more strange beasts appear from out of it. The maids attempt to fight using their full powers, but to their astonishment find their skills and levels to be reduced since their revival. Momonga then takes control of the situation and orders the maids to fall back for now. Though the protagonist refuses to retreat, opting to fight beside Momonga which the Overlord permits him to do under his permission.

The two defeat the invaders who have left strange purple crystals. It becomes clear to Momonga that they are not in YGGDRASIL anymore. Momonga then resurrects Albedo who too cannot recall anything about her death and organizes a plan to retake the dungeon. So far, there are other Cracks that were found in Nazarick and have been heavily guarded by undead summons. The need to understand what is going on is paramount. Faced with an unknown world and enemies, Momonga becomes overwhelmed by the losses, until the protagonist encourages his master to persevere. The homunculus volunteers himself to explore beyond Nazarick, citing that while he was weak, he is the perfect candidate as his revival costs were minimal compared to the rest of the NPCs. Despite the practicality, Momonga still does not wish to send off a child of his comrades to his potential death. But the protagonist pleads to be of some service to give his life meaning. Seeing the determination in the homunculus' words, Momonga agrees to give the protagonist a mission.

Before setting out, a slime Mercenary NPC that was summoned using YGGDRASIL gold coins by Momonga was set out to help the protagonist 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 and Narberal Gamma to find survivors and interact with them. Unfortunately, the [Gate] transport was affected by the close vicinity of a Crack, throwing them off course. The three used the slime to detect any dangers such as wild slimes. Eventually, Narberal and the protagonist adopted calling the slime, Slimeko for convenience sake and later had her create the alias Surako while in public with human society.

The protagonist and his 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 and the protagonist gain insightful information on the New World. 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, the group learned that Nemu's 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, the protagonist and comrades joined the adventurers in finding Enri. However, all they could find was a severed arm and brought it back to the village. While the villagers were evacuated by the Swords of Darkness, the trio remained with the Scripture to investigate clues on the Cracks. With his comrades, he 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.

During the interim of the adventure, the protagonist briefly returned to Nazarick and took a respite by organizing the books in the library. He was summoned by Momonga to conduct a survey of all the NPCs desires and their overall happiness. After regrouping with the Sunlight Scripture, Narberal had departed to return to Nazarick. Both the protagonist and Slimeko stayed behind, with the latter acting as a relay to deliver a report to Momonga. They were joined by the dark elf twins Mare Bello Fiore and Aura Bella Fiora to help them in the investigation. The protagonist and Slimeko 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. After the beast was beaten by Aura she made it her pet, and forced her, now named Hamsuke, to guide them to the Crack.

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 many to defeat on their own. It was then they were rescued by Leinas Rockbruise and her imperial knights who were sent from E-Rantel. Together with the knights, they fought against 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.

The protagonist would briefly return to Nazarick and be greeted warmly by members of the Pleiades. When not in his library he would accompany some of his colleagues and observe the dungeon's defenses against the Crack conducted by Shalltear. He would also provide consultation to many NPCs seeking other ways of improve their abilities in areas such as strategy and work ethic. And he would have other opportunities to meet the other members of Nazarick such as Pandora's Actor who attempted to fool him while disguised as Momonga.

The protagonist and Slimeko would accompany Ian to the city of E-Rantel, where they were greeted by Saint Clementine. Though the homunculus and slime 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 given 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 up 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 with a reason where he would much prefer 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. Later, the trio took on their first mission to examine the sewers of E-Rantel and report the status of the sanitary slimes there. The team discovered that the slimes had underwent some mutation to the point where they seemingly become more aggressive and hungry. After killing all the slimes in the area, they return back to the guild with the samples. There they made 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. It's 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. The protagonist face off 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.

The protagonist would later be part of a mission organized by Albedo to acquire a flower tree for a hanami for Momonga. To find something suitable, he, Slimeko and Narberal went to a tavern in E-Rantel and learned about the existence of the Legendary Tree. Once Albedo was informed that it was rumored to exist in the Tob Forests, she commanded the protagonist to join an expedition to search and retrieve it. During his stay in Nazarick, the protagonist made more friends with the other NPCs of the dungeon, forming a rapport with Neuronist Painkill as she knowledge seeker like him, albeit in a different manner.

The homunculus's adventurer duties and Nazarick's agendas would intersect in some cases. At the time when Nazarick was covertly using an abandoned mine near E-Rantel to acquire minerals, the Re-Estize Kingdom had send several adventures led by Blue Roses to reclaim it. The protagonist and his partner Slimeko aka Surako infiltrated the ranks of the adventurers on the mission and monitored Blue Roses progress as they pushed through every obstacle Nazarick sent to deter them. It took the discreet activation of a poisonous gas trigger to finally force the adventurers to retreat and then declare the mine to be usable thus allowing Nazarick to continue their operation without interference.

More unexpected events would occur in Nazarick that required the protagonist's attention like entertaining guests from beyond the Crack. And on another occasion organizing a contest between Albedo and Shalltear to judge who was more worthy of being a queen to Momonga. Though after the two took the tests it ended in a draw, causing the two women to demand the homunculus to make another ruling. The homunculus refused as he stood by the results, leading both Floor Guardians to seek another evaluation from Momonga himself. He would also partake in a mission to explore an island that Shalltear opened using an unstable [Gate]. There with the Pleiades, he and Slimeko were able to locate a forgotten pirate port, salvaging lost cargo to bring to Nazarick.

The protagonist's adventurer team's fame would eventually rise due to protagonist's deeds becoming more publicly acknowledged. 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 to that, 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. They search through the debris and eventually found the personal effects of Enri Emmot. Upon their return to the city, Slimeko hand over the items to Lizzie, who hoped that Enri's former belongings 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, the protagonist and Slimeko 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. The protagonist'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 other words, 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. The protagonist's 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 serve as bait on luring them out. 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. Slimeko then retrieves the slime core to show as proof of their kill to the city representatives.

There would be other missions assigned to the protagonist by Momonga, such as surveying a newly opened area of a mine to seek out new veins of ores. And in other instances help prevent an infestation of seemingly unkillable Pumpkin Monsters in the dungeon after it was found out that there were contaminated by miasma from the Cracks. Recalling a similar situation happened in YGGDRASIL during the Halloween Festival event, the homunculus provide Aura and Mare the tools and method on how to kill the monsters. Around the same time new visitors from another world stayed as guest to Nazarick, this time a battalion of magic caster soldiers, and the protagonist chaperoned them while outside of the dungeon.

While back in E-Rantel, the protagonist having ended a conversation with Leinas, learns that a lizardman named Zaryusu Shasha attempted to enter the city was turned away by the guards. Hearing that the demi-human was seeking to acquire the aid of adventurers to investigate the cause of the rising temperature of the Great Lake, the protagonist and Surako go to introduce themselves to take up his request. The request is taken as the protagonist suspects that the temperature change in the lake is actually Caloric Stones. Once the adventurer gets approval from Momonga, he, Surako, Aura and Cocytus join Zaryusu to uncover the mystery. In the end they discover that it was actually due a mineral that emitted heat spilled into the Great Lake from the mountains. Though it was not a World Item the mineral was still of some use to Nazarick and the results opened a dialogue with Green Claw.

Upon returning to Nazarick, the protagonist and his 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 said, 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 and wearing several clothes donated from a pair of helpful civilians who lend aid to their task. 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 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 the best of 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.

Later the protagonist would be involved in several Nazarick hosted events like a fighting tournament. And also go on a quest to locate the Pure White Peryton and hunt it for the main dish at Nazarick's Christmas party. In an incident which saw Nazarick being under some sort of spell that caused all the NPCs within the dungeon to celebrate the New Year holiday, the protagonist and his team being away from the dungeon when it happened were unaffected. Momonga seeing that the spell needed to be broken, recalled the protagonist and his friends to join him and Shalltear in investigating Fake Nazarick where a strange Chaos Zone was formed. There they found the real mastermind behind the New Year atmosphere, a being named Shiramochi-ō. Though the entity and his summons were defeated and the spell should have been broken, Shiramochi-ō used the last bit of his power to rewind time, creating a new loop of the event. In the new timeline, the protagonist and his allies were once again called back to Nazarick to figure of the source of the New Year's epidemic, though this time they were joined by Sebas Tian and also a strange boy named Shiro who appeared in the dungeon. As the adventurer progressed with Shiro bonding with the denizens of Nazatick, it was revealed that he was actually an amnesiac Shiramochi-ō. Once the White Mochi King regained his memories, he was obligated to be their enemy by his creators. However due to the amiably company and his respect for his new friends he refused, and voluntarily sacrificed himself to free the Nazarick of the spell. After the spell was broken, the protagonist was one of the few who still retained their memories of the event.

The decision made by the protagonist over the Queen War would eventually come back to haunt, as Shalltear would come to him though this time bringing him an idea as to why Momonga refused to make the decision of which suitor should be queen. She insisted that it was a test from Momonga called the "Trial of Love" to see if either she or Albedo had the tenacity to continue pursuing him. Though the idea was strange the protagonist could not discount it as a hidden agenda by Momonga and agreed to aid Shalltear in devising a strategy that would win the Overlord's heart. Their plan worked as it attracted Momonga's attention as Shalltear began take her duties with more seriousness without the usual lewdness when interacting with Momonga. While it seemed that Shalltear was about to pass the so-called "Trial of Love", Momonga revealed that they did not. Disappointed the protagonist hoped that Shalltear would pass the trial again in the future.

The protagonist and his friends having accepted a job from the royal family, chaperoned them 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 from here on out. 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 the protagonist and 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.

The protagonist and his 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, the protagonist'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 met up 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 which in turn led to saving the city and earning the Alliance's gratitude.

To understand the power behind the Cracks, Momonga would launch an expedition to a nation that had fallen to its power, the Roble Holy Kingdom. The protagonist and his adventurer team also accompanied him to act as intermediaries in case they encountered any surviving humans. There the expedition examined the ruins such as the Great Wall and also Kalinsha, getting a general idea of how the nation succumbed to the Chaos Beasts. At the city of Kalinsha the expedition came across a Dragon Chaos Beast within a cathedral. It was the protagonist who determined that the dragon monster was guarding something as it refused to fly from the area. The item was then recovered by Nazarick after its guardian was defeated.

Some new arrivals from another world would appear in Nazarick, though one of their unexpected guests had a mental breakdown reverting to a dark personality due to extreme stress after arriving in Nazarick. It prompted both Nazarick and their guests to work together to defuse the troubled entity with the protagonist acting as the main negotiator. After the crisis was averted, the protagonist took a break in the cantina to enjoy a hearty meal.

Albedo would solicit the aid of the protagonist and his team again to search the Tob Forest, this time to locate the real Legendary Tree to use it as part of a command tower for Nazarick's Enhanced Treants. He would also aid the Overseer Guardian again, though it was to help her devise a means to seduce Momonga. To get her close to Momonga the plan was to have Albedo become a maid on the 9th Floor and slowly gain his trust in order to arrange for her to be alone with him and force herself on the undead. However his and Slimeko's assistance was found out by Solution after they were interrogated, who reported the plan to Shalltear, saving Momonga from being raped by the Overseer Guardian.

To gather more resources for Nazarick, the protagonist would join a mining survey team composed of several of his comrades and a new batch of visitors from another world. The plan was to locate a gold vein that was believed to be located somewhere near the depths of the Azerlisia Mountains. Upon finding it the protagonists witnessed one of this team's new allies cast a powerful spell that destroyed a Fire Dragon hoarding the gold ore.

After word reached Nazarick that there was evidence of players in a seaside village, the protagonist and his adventurer team were dispatched to validate it. Coincidentally they met up with Blue Roses there who were seeking a dwarf named Tsuibayaya who was also the the one the Nazarick agents were searching for. Under the cover story that they were seeking the dwarf to have him forge new armor and weapons for them, the protagonist's team worked with the team to locate Tsuibayaya. They found the dwarf at the beach searching for the Legendary Mermaid and would only fulfill the adventurers requests unless they brought him the scales of the Legendary Mermaid that he wished to use to create the Sage's Swimsuit. The adventurers worked to decode the legend that would lead them to the mermaid with the protagonist's team undertaking the task to find the place where the entity lived, whilst Blue Roses retrieved the key. Once the Legendary Mermaid was found and his scales were acquired they brought them to Tsuibayaya. The dwarf them pleased with the final product gave it to Gagaran and provided the armors he promised Blue Roses. While seeing the members of Blue Roses off, the dwarf expressed that he was at a loss what to do as he finally accomplished in creating the perfect swimsuit. However the protagonist reignited the dwarf's craftsman spirit by having members of the Pleiades show themselves wearing swimsuits after which Tsuibayaya pledged to work with Nazarick to create new variants.

The protagonist would deal with more difficult task like escorting a paranoid visitor from another world followed by his trio of so-called goddesses to the Tob Forest to allow them to hunt for their own food. Though their hunt is interrupted when a being called the Grim Reaper came and attacked them forcing the protagonist to get his charges and him to safety until the situation could get under control. More unpleasant tasks would come before the homunculus such as reluctantly investigating one of their own, Sebas Tian who was suspected by Solution to be trading Nazarick's secrets to a third party. Both he and Slimeko hoped the accusations were false but they followed their orders from Momonga to look into a brothel in the Black Market where Sebas Tina was frequenting. Their investigation led to learning that Sebas Tian was not actually a traitor but pursuing a personal independent investigation in the criminal underground of E-Rantel that was controlled by Cocco Doll to free a woman named Tuare at the brothel. The undercover adventurers helped arrest Cocco Doll, but when they went to retrieve Tuare at the brothel they found that it was actually a feeding ground for a sinister demonness named Isabella. The existence of a New World demon caused the protagonist and his allies to see the value in capturing her for information. Once the demon was properly contained in the confines of Soi's body, the protagonist provided a false story that the demon escape to the city officials. And he was pleased to witness Momonga officially bringing the matter of Sebas Tian's loyalty to Nazarick to a close.

He would encounter some new visitors from another world, who came from a Crack outside of Nazarick, at E-Rantel where he team greeted and befriended them. Though it of course was to gauge the visitors on their threat level and to inquire about some information on another group of visitors that found snactuary in Nazarick. It was the protagonist who arranged the two groups to meet and incite a conflict at Momonga's orders in order to determine who were the aggressors and the injured party in the conflict. Once it was determined to the Overlord that the one she sheltered were being harassed by the other faction, the protagonist and his allies were permitted to defend the former and allow them to escape back to their world via a Crack.

During a meeting with Demiurge who asked the protagonist and Slimeko 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, the protagonist and his 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 from that moment forward. 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 found 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 as well.

After the opponents are taken care of, the protagonist volunteers 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 along while following the trail of blood and bodies they encounter. 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 was found that Gazef Stronoff is the only survivor there 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. The protagonist and his 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 that stood in their way. They succeed in slaying the monster, which is then turned over to Nazarick for study while they transport Gazef back to E-Rantel.

Once they return Gazef back to the Kingdom, the protagonist and Slimeko attended 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 together 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.

After Emperor Jircniv Rune Farlord El Nix accepted a deal with the Demon Emperor Jaldabaoth to defeat an army of Chaos Beasts to save E-Rantel, the demon and his band began to collect their payment which was all the wealth of the city and the emperor's life. At the eve of the emperor's execution in the city square, the protagonist seemingly appeared to save the emperor from danger. He rallied the defeated citizens of E-Rantel to take arms to drive out the demons from E-Rantel. The protagonist proceeded to display his strength by defeating the Evil Lords and Abyss Demon. Next, his battle with Jaldabaoth ended with the demon making a full retreat after having lost to him in combat. The act of valor and his courage inspired the citizens of the Alliance to hail the protagonist as a hero to the people. Unknown to the populace, it was all staged by Nazarick and the one who assumed the protagonist identity was none other than Pandora's Actor.

Back in Nazarick, the hot spring facilities of the dungeon were reported to be back to working order. Taking an interest in hot springs in culture, the protagonist collected material from the library on the matter. The renewed interest on the baths also opened another matter such as Solution's desire to be Momonga's bathing attendant, followed by several of the other female NPCs. To resolve the matter the Miyoshi Cup was created to decide who among the participants would be selected to challenge Momonga's current bathing attendant. For the event the protagonist and Demiurge acted as commentators.

While out on a mission to E-Rantel to gather food supplies for Nazarick's second Christmas party, the protagonist missed an emergency meeting called into session by Momonga and the Floor Guardians to address a mysterious cold front that was affecting the lizardmen tribes in the Great Lake. Since the adventurers were on another assignment, three members of the Pleiades were sent to investigate. When several previous visitors from another world had returned to Nazraick, and being targeted by an evil clone, he would play another role in setting up a date between Leinas Rockbruise and one of the visitors from the other world. This was a trap to attract the clone's attention whilst the forces of Nazraick laid in wait around E-Rantel to ambush it.

The protagonist would launch several projects in Nazarick such as using leftover Valentine Chocolate from YGGDRASIL's Valentine's Day event to be used for diplomatic purposes for the Sorcerer Kingdom. To create a confection that was acceptable to the taste of the inhabitants of the New World, he oversaw Project Valentine and hosted a cook-off among the female Floor Guardians. Another plan proposed by him was to improve the mental health of the inhabitants of E-Rantel after their harrowing experience by the Demon Emperor. It led to the creation of testing an idol plan and LittleMass which was composed of Shalltear and Aura as the singing idols. The protagonist acted as the idols' manager during their act in Nazarick.

The idol plan was deemed a success based on the positive feedback from the general maids and so a similar event was hosted outside Nazarick in E-Rantel in the form of an adventurer exhibition. The protagonist worked with Pluton Ainzach to coordinate the event using his popularity and backing back the Sorcerer Kingdom and also the Tripartite Alliance. Since the event would require him to fight, he had Pandora's Actor disguise himself as the "Dark Warrior" to fight in his stead while he coordinated from his inn room during the matches.

In regards to the protagonist's part in the attack on E-Rantel by the Demon Emperor, in reality the former had allowed Pandora's Actor to assume his identity during the demonic raid. To make the Area Guardian's cover more believable for others to accept without suspicion, the protagonist willingly allowed a Lip Bug to extract his vocal chords so that his voice could be used by the former. Though the procedure was painful, the protagonist had no regrets considering it a small sacrifice to further Momonga's interests. The homunculus recovered thanks to healing magic and once the operation was done, he attended a meeting with all the participants before Momonga. Momonga pleased with their work, permitted each of the participants to be granted a request. When it came to the protagonist, the homunculus requested to separate from Nazarick. His wished initially caused cold tension in the meeting, as it was almost treasonous, but the protagonist explained that now that his so-called heroics have made him the spotlight in the eyes of the Tripartite Alliance, in order to safeguard his association with Nazarick he would need to stay away from them to avoid a possible future scandal to ensue. Plus now that the nations in the Alliance were turning to him to manage E-Rantel, permanently staying there was more practical to make the city more effective. His reasons for the extended leave from Nazraick was approved by Momonga though he was reminded to keep daily reports of the situation in E-Rantel nonetheless.

The protagonist would then soon attend a summit of the leaders of the Tripartite Alliance, where King Ramposa III would officially transfer the city's administration rights to the protagonist's nation. This was in part due to the many successful initiatives of the protagonist. This includes how it led to the completion of the Fourth Wall in E-Rantel, expansion of farming lands, residences, peaceful integration of demi-humans and the expansion of the labor and defense force. Since the signing of the rights required a person of high station from their side to attend, Albedo invited herself to the meeting, acting as the Prime Minister of their home nation.

At the venue of the Alliance, the signing was about to be formalized, though there were voices of objection from Enhela and Cardinal Rayond. The members of the delegation of the Slane Theocracy seeing that the protagonist represented a non-human nation were wary that giving the rights of the city would lead to an abuse of power under one individual. To allay their fears, both Albedo and the protagonist assured them that they had no interest in mongering power, and their first concern was to resolve the incidents with the Cracks. However, the Theocracy was permitted to act as a deterrent, in that if there were any breaches in trust, the Alliance would have every right to retract the administration rights from the protagonist's nation. The Theocracy content with that offer retracted its objection and from there, the newly revealed Sorcerer Kingdom signed a treaty with the Tripartite Alliance.

Once the signing was completed by Albedo, the protagonist set off to complete his duties as the new Territory Guardian of E-Rantel. His first action was to do an inspection of the new E-Rantel Magic Research Institute where he installed Nfirea Bareare as director, after he previously solicited his help by bribing him with a Minor Healing Potion. After arriving at the institute, the protagonist and his friends were given a tour of the facilities that were geared towards investigating all topics related to the Cracks. Once there, they found Fluder Paradyne upon arrival as he had previously been recruited by the protagonist by sharing his knowledge of Ashurbanipal and promise to meet the Supreme Being. The protagonist found Gazef Stronoff in the institute as the staff were still trying to develop a cure for the warrior's contamination. After the protagonist participated in fighting against Gazef's strength to allow Fluder to gain some data, he and his friends left the area. Returning back to the Alliance's venue, he was contacted by Blue Roses who reported that they had finished constructing a cordon around the Northern Cave.

When Shalltear failed to return back to Nazarick from her mission at the Northern Cave, and came under the influence of a World Item, the protagonist was present at the emergency meeting where Momonga announced that he would battle to kill Shalltear to release the vampire from the mental control. Like many of those that attended the meeting he rejected the idea as it put too much risk on Momonga. The protagonist instead managed to convince Momonga on an alternative plan, by using an army of summons led by his adventurer team and support by Albedo and Mare to fight Shalltear. Before fighting Shalltear, the homunculus engaged with Shalltear in a conversation to learn more about the enemy who did this to her, but after interviewing her he found less than satisfactory answers. The moment he ordered Nazrick's forces to attack Shalltear became hostile and intent on targeting the protagonist. The vampire managed to defeat all the forces the homunculus put into play. Just before Shalltear was about to kill the protagonist, he is saved by Cocytus. Aura using Depiction of Nature and Society as planned by the protagonist is used to drag Shalltear into another dimension. There Momonga is waiting to slay a weakened Shalltear. After the vampire's revival in Nazarick and the ill news that an unknown enemy was out there in the New World, the protagonist became more aware that his position as Territory Guardian was now more important for Nazarick in order to uncover the perpetrators of the heinous attack on his comrade.

Abilities and Powers
The protagonist's abilities and class are generally at level one due to his race. But thanks to his magical equipment gifted by Momonga, he can overcome his weaknesses, rising to the rank of a platinum ranked adventurer.

Momonga
Before the transfer to the New World, Momonga never knew of the protagonist's existence or that there was a position of Deputy Assistant Diplomat in Nazarick. However after the protagonist was vouched for by one of his creator's other creations, Momonga began to trust him. As time went on, the Overlord came to rely on the homunculus to be his eyes and ears in the New World. Due to the success of the homunculus and his diplomatic skills, Momonga now has the utmost faith in the NPC's abilities. The Protagonist when it comes to Momonga follows a simple creed and that is to always to lighten the burden Momonga has as a leader.

Slimeko
The protagonist has a close relationship with the slime. He originally had treated her like a normal expendable summon. However, after realizing she had a personality of her own, he changed his attitude towards the slime and began treating her with more consideration. Ever since then, they have been paired up together for going on missions and are inseparable from each other. Even during their time off at Nazarick, the two would usually find themselves together again in the same library while re-organizing the books.

Neuronist Painkill
Neuronist Painkill was one of the NPCs that were killed during the transfer to the New World. Due to her death, her duties were temporarily given to Shalltear and Demiurge. After she was revived and tried to resume her duties, Neuronist found her information she gleamed from her torture victims to be outdated as the information was already acquired by the protagonist out in the field. She began to feel marginalized and became envious of the homunculus. However her envy was short-lived as after she met with the protagonist, she found the that they were alike as they gathered information for the benefit of Nazarick and Momonga. After his words of comfort that she possessed skills the protagonist lacked, it invigorated her to return to her duties with more passion.

Trivia
