Tia (ティア) is an adamantite ranked adventurer and a member of Blue Roses. She is also the triplet sister of Tina and Tira.


Tia has a slender figure with fair skin, coral eyes and blond hair that is tied to a ponytail with a blue string.

Her kunoichi outfit consist on black half-breastplate over a sleeveless mesh bodysuit, a black and blue striped headband, light orange scarf with blue flower pattern, black arm gloves with metal bracers, a light orange hakama pants and black boots with metal plate around the shin and instep.

When not on duty, she wears a simple dark-colored yukata tied with a blue obi and a long yellow scarf which falls to her sheen.


Raised as an assassin, she is cold, professional and the loss of human life almost never affected her emotionally. However, after joining Lakyus, she gradually developed feelings for her fellow members of Blue Roses.


Both she and her sister were raised in the arts of an assassin and never trusted anyone, but themselves only. They were once tasked to assassinate Lakyus. However, they failed as she had proved herself more than an easy target. After tailing Lakyus in an attempt to discover and exploit any weakness of hers they could utilize to execute their assassination, they eventually decided during this time that the life of an adventurer suits them better.


The Men in the Kingdom Arc[]

Together with her sister Tina, the stealthy pair raided a drug production village belonging to Eight Fingers. After a thorough cleanup of the facility, the two set fire to the fields ones that were being used to grow the drug beforehand, razing the facility to the ground and removing any trace of the Blue Roses involvements with its destruction. During their infiltration, the pair retrieved several documents which they had deemed to be the only items of import for their Mission. After this, they return to the other members of Blue Rose. Leaving the vicinity soon afterward.[1]

Later on, she partnered up with both Gagaran and Evileye in order to defeat Entoma. As a result of their strong team cooperation, they nearly succeeded in killing her. This was stopped by the arrival of Jaldabaoth, who managed to save Entoma before the three of them could deal the finishing blow. Shortly afterward, she was killed along with Gagaran by Jaldabaoth's Hellfire Wall.[2]

Along the way, Tia and Gagaran were soon revived by Lakyus. Despite the drain in their strength, they still resolve to join the fight against the demon army that was attacking the Re-Estize Kingdom.[3] After the attack was over, Tia was present along with the other Blue Rose Members to bid farewell to Momon after the whole crisis had passed.[4]

In a conversation between Renner and Blue Roses, it is known that Lakyus is helping Gagaran and Tia to recover the experience they lost when they got killed by Jaldabaoth, by constantly placing themselves in danger.[5]

The Paladin of the Holy Kingdom Arc[]

Main article: The Paladin of the Holy Kingdom Arc

The twins are present in the meeting with the delegates from the Roble Holy Kingdom along with the other members of Blue Roses where they asked for Neia's name noticing she doesn't have the body of a warrior. Because of their mischievous nature, both she and her twin sister then resorted to making jokes regarding Gagaran's unique huge physique by comparing it to Neia Baraja. It's unclear who did it, but Evileye signaled to one of the twins including Tia to examine the small pouch of money handed over to them by the envoy Gustav. It is their job to check and see if the small pouch actually contained the expected amount by throwing it up and catching it to feel the weight sensationally.

When Evileye drew the identity of Jaldabaoth on paper to Remedios, it was either one of the twins like Tia who snatched back the former's drawing and tore it in half. While Evileye was furious and distracted about what one of them did, the other twin took the chance to snatch away the pen in the meantime and drew swiftly on the new piece of paper. One of the twins then showed Evileye their finished drawing of Jaldabaoth which was of far greater quality than the picture drawn by their companion. The twins and Evileye ceased their feuding concerning the drawing of Jaldabaoth and turned back towards Remedios after the paladin confirms that was the demon they fought against at the Holy Kingdom.[6]

The Witch of the Falling Kingdom Arc[]

Main article: The Witch of the Falling Kingdom Arc

Before opening the doors to the inn where the secret meeting arranged between Blue Roses, Red Drop, and their unknown client was held at, Tia and her sister tapped their leader twice on her waist to signal for her to be on alert as they have noticed something. After entering the secret meeting room and seeing that Evileye had done the job of taking out the two women that were with Azuth Aindra, she decided to give the vampire a rough explanation of the methods for how women weaponize their femininity to which her colleague instead ignored and spoke to Lakyus instead. Upon noticing the presence of their clients, she called out to her boss to indicate that their clients have finally arrive to their meeting.

When the 10th Seat of the Black Scripture revealed his hidden presence to them, Tia and her twin sister were the first to be left utterly shocked by how that assassin appears out of nowhere unnoticed by them. As a result, she and her twin immediately drew their weapon out of caution due to the fact that a new guest having suddenly appear before them, acknowledging the latter to be an assassin who is far stronger than the two.[7]

Although the capital Re-Estize is already surrounded by the Sorcerer Kingdom's forces, Tia and the rest of the members from Blue Roses met up with Renner, Climb, and Brain in the palace. Once Evileye suggests Lakyus that they have enough time to drink some cup of tea together, Tia follows along with her ploy. Tia decides to steep and pour a drink of tea for Lakyus why the latter talks with Renner. Tia guaranteed to Lakyus that the tea will be richer than she could dream of, causing the latter to believe that they are really looking to drink Renner's tea out of kindness for the princess who offered it to them.

After pouring five servings of tea, Tia swung the Warm Bottle around as if to emphasize the fact that it was empty. Tia then signals to her sister Tina to drag Brain Unglaus out of the room for the time being as Evileye, and Gagaran will take care of the rest until she makes a return. Leaving Brain to Tina to take care of, Tia heads back to the room alone with the Warm Bottle. She reasons with Lakyus that the other two who are not here with her are looking for desserts to pair with the tea.

Upon seeing her leader drink the tea and the drug effect finally kicking in, she with Gagaran immediately spring into action and start repeatedly throwing heavy jabs at the defenseless Lakyus without any equipment to protect herself. While Lakyus is weakened by whatever effect the drug has on her and before getting the chance to use magic, Tia and Gagaran continues hitting their leader simultaneously until the latter became weak and injured enough to be affected by Evileye's spell, [Charm Person]. To make this happen, Tia impaled Lakyus with a few spiky needles as the air was knocked out of the latter, rendering her leader unable to breathe.

Tia admits that she had been making careful observations for quite a while now, looking for ways to neutralize Lakyus. She mutters to Lakyus that normal methods would be resisted by the latter, so a combination of magic and poison would have to be used altogether against her to ensure she is in a weaken state. Tia doubts that someone like Lakyus would even be capable of resisting the effect of multiple poisons simultaneously. When she finally did her job, Tia leave it to Evileye to finish her off with the [Charm Person] spell so that they could carry out their escape plan without being opposed by their leader.

After Lakyus was under Evileye's mind-control and starts healing herself, Tia was instructed by Evileye to not do anything rash that may ruin their plan. Hence, Tia decided not to pull out the needles she had impale inside her leader's body due to the likelihood that the pain of taking it out would result in dispelling the mind-control spell and causing Lakyus to turn hostile. Once Lakyus is fully healed and remove the needles herself, Tia and the other members awaited her sister's return to the room. After Tina came back, Tia and the rest of Blue Roses depart with their leader to go and retrieve her equipment in the inn before teleporting away from the Royal Capital.[8]

Main article: Mass for the Dead Arc

Tia was seen with Gagaran at a dining together at a local pub in the Royal Capital. When Gagaran spots Zero and Peshurian pass and inquires who the are to the assassin, Tia explains that they were former members of Eight Fingers. Tough their past was shady, Tia noted the good that the former criminals have done since the Catastrophe, commenting they may have reformed like herself.[9]

When there was a string of thefts among the refugees coming into the capital, Lakyus had Tia and her sister Tina investigate the issue from behind the scenes.[10] Tia was absent with her sister when Princess Renner had a meeting with Lakyus and Gagaran. Lakyus when asked on their whereabouts replied that they were doing research.[11] They later joined the meeting at the palace just when Gagaran left to get a drink from the city. Once the meeting was over, all of Blue Roses regrouped together so that Lakyus could inform the women of their new task from the Kingdom, which was to reclaim a mine infested with monsters.[12]

At the mine Tia's team were supported by other adventurers to do the monster extermination. Among them was the protagonist and Surako. Most of the adventurers they brought were killed by the monsters and also demons that were introduced into the mine, by a cult. Rather than retreat, Tia and her friends pressed forward and finally got to the deepest part of the mine and faced the Abyss Demon. After Lakyus dealt a grievous wound on the demon, the mine began filling with poisonous gas forcing the adventurers to retreat. In the end the recovery of the mine failed, but Blue Roses took comfort in having destroyed a demon nest.[13]

At E-Rantel, Tia's team assisted in an investigation of the missing refugees in E-Rantel. The assassin worked with her sister to collect information on those that vanished. Their investigation was joined by the protagonist and Surako, and a new adventurer named Soi who surprised Tia and her sister when the other woman was able to detect them. Tia particularly takes a liking to Soi and is paired up with her for the mission. The adventurers catch their first suspect, thanks to supposedly Soi who launched a needle projectile at him preventing the suspect from taking his life. The skill impresses Tia and she tries to flirt with her junior, only to be taken away by Lakyus so that they can interrogate the prisoner. The information leads the investigation to the E-Rantel's Cemetery, where they discover Six Arms to be working with Zurrernorn to complete their Death Spiral. Tia and her twin fought against Succulent and Peshurian. Once all the members of Six Arms were defeated, only Khajiit Dale Badantel was left and was about to initiate the ritual, until he is struck with a needle projectile and is killed. Tia buys Soi's claim that she threw the weapon at the cultist.[14]

Later when the summit of the Tripartite Alliance took place in E-Rantel, Tia worked with her team to locate Zero who had escaped arrest. The adventurers also witness a growing mob demanding entry into the inner city, which was closed for the Alliance's venue, and help to act as crowd until the people calmed down. However the crowd was broken up when news of a horde of Chaos Beasts approaching the city disseminated. Tia joined in the defense of the city to protect the residents whilst the protagonist and his team engaged the leader of the horde.[15]

On another mission for the royal family to pick up armors from a dwarf blacksmith at a seaside village, Tia and her team reunited with the protagonist's team and his companion Narberal Gamma. They were unable to locate the dwarf, Tsuibayaya, at the village, but followed his whereabouts to the cove, saving him from being eaten by some Giant Crustaceans. As he was on a mission of his own and thus unable to give the armors just yet, he allowed the adventurers to locate the Legendary Mermaid for him and retrieve its scales. To equip the members of Blue Roses, the dwarf loaned them several swimsuits to wear in their water environment. Blue Roses separated up from the protagonist to locate the Promise Stone required to meeting the mermaid, while the former searched for the entrance to the mermaid's lair. When the two group found both they used them to summon the Legendary Mermaid and after defeating the famed entity in a duel they were rewarded the scales. The scales were then given to Tsuibayaya who used them to create his masterpiece, which was given and wore by Gagaran much to Tia's disgust.[16]

Tia reappeared again with Blue Roses when they located a cave north of the city and where Gazef Stronoff vanished. She worked with her team and the protagonist to eliminate two Spear Chaos Beasts that were guarding the entrance.[17] After the Chaos Beasts were killed, Tia and the other remained at the entrance to guard it while the protagonist and his team searched and recovered the Warrior Captain.[18]

At the time of the attack on E-Rantel by Jaldabaoth's horde of demons, Tia joined Blue Roses in defending the city. She and Blue Roses also witnessed the protagonist save the Bloody Emperor from being executed by the demons, commenting on how strong their was.[19]

A few weeks after the attack, the city of E-Rantel was beginning to heal. To raise the spirits and also amount of defenders for the Kingdom. the protagonist organized an adventurer tournament. Tia came to participate at the invitation of the protagonist. A day before the start of the tournament she and her team met with the organizer and his assistant to touch base on the event.[20] Tia and Tina fought in the first exhibition match against her teammate Gagaran, which led to her defeat. Though she was defeated by the muscle warrior, she and her sister claimed that they were going easy on her out of respect to Lakyus. In the tournament Tia grew interested in the two newcomers Shall and Ku. She would later join her team in fighting the pair in the seventh match and later fought the "Dark Warrior" as part of the finale of the event.[21]

Tia would join her team and the protagonist in investigating Re-Blumrushur to see if Marquis Blumrush was responsible for a string of disappearances of brides seeking to answer his solicitation to be his wife. Tia and the others busied themselves in collecting testimonies from the victim's families. Tia and the others would be approached by a desperate soldier seeking aid to eliminate undead that infested the mine near the city. Though the adventurers had priorities, the protagonist convinced them to help since could. Tia and her sister Tina remained behind in the city to continue collecting information.

The undead appearing in the mine turned out to be related to their investigation as they found that the undead were amassing due to the remnants of Zurrernorn conducting their rituals using the captured brides as sacrifices The adventurers killed the cultists and later found Evil Lord Greed at the scene. Since he was present it led the members of Blue Roses to believe that Blumrush was associating himself with the Demon Emperor. The twins eventually caught up their their fellow comrades, after informing the local Adventurer's Guild of the noble's crimes allowing the local adventurers to arrest those involved at the estate. After the mine collapsed, Tia and her friends enjoyed their victory and also found began teasing Evileye on how cute she looked in her bridal gown.[22]

When the E-Rantel Magic Research Institute was formed by the protagonist, Tia and her team journeyed with several researchers to cordon the Northern Cave to prevent more Chaos Beasts from escaping to the surface. While working to establish a defensive perimeter the assassin hoped that the researchers could solve the mystery of the Crack so that her team could resume working as adventurers.[23]

While away from E-Rantel, Tia and her team were in a job to infiltrate an illegal gambling hall to retrieve a wayward son of a noble. Using Hide Shadow technique Tia and her sister infiltrated the area along with Lakyus and Evileye in disguise. After the women finished the job and were heading back, they received word from Renner that a group of strangers were impersonating them. Evileye was extremely flustered by this violation of her identity being used especially when her imposter took the form of her in a bunny girl costume. The assassin tried to convince Evileye that the outfit was not that bad to no avail.[24]

Tia's twin sister, a fellow "ninja" and adamantite adventurer of Blue Rose.

Lakyus Alvein Dale Aindra[]

Tia and her sister were originally supposed to assassinate Lakyus. However, they ended up failing. They decided to follow her in order to learn her weaknesses. After some time, they decided to quit being assassins and become adventurers instead, joining Lakyus' team. Tia now considers her a good friend and trusted teammate. She and her sister often refers to Lakyus as "boss."

However despite their friendship and her now working together as Adamantite Adventurers and going on numerous quests and journeys together, Tia was shown to still analyze and study Lakyus for weaknesses to successfully kill her out of habit as an assassin. This was the case where they silently scheme to force Lakyus to escape with them during the final stages of the Sorcerer Kingdom's invasion against the Re-Estize Kingdom without her noticing bore falling into their trap. Tia was shown to have successfully come up with the accurate deduction that in order to weaken Lakyus enough and remove and thin out her natural resistances, they would need to first have her be unequipped without her high level items and equipment, have her guard completely lowered, poison her with at least five-widely different poisons and then physically weaken her enough with physical attacks to render her weak enough to be affected by mind control magic.


Tia risked her life to fight alongside Gagaran against Jaldabaoth. After being resurrected, the two of them have been training to regain their strength.

  • (About Gagaran): "Surprisingly, it seems that the blood flowing through Gagaran really is red."
  • (To Evileye): "We were trained to do those things back then as well. Women who were not gifted in raw power or arcane talents could only resort to weaponizing their femininity. Though Gagaran cannot relate at all, I’ll still explain their methods. First—"
  • (To both Renner and Climb about Lakyus): "Defending the capital was evil boss' decision anyways. We were against it deep down from the start."
