"Kamiya Tsurugi, 26 years old! 13 years of wage slavery!"

Tsurugi Kamiya (狼谷 吊戯) is an extremely powerful member of C3. He is said to be the “Ace of C3” and is Touma’s human experiment in an attempt to create a ninth servamp.


Tsurugi Kamiya is a 26 year old male with gold eyes and black hair. He has pale skin and is smaller than his teammates at C3. He is often seen wearing his C3 uniform, which resembles a straitjacket. He wears bands around his wrists that hang down and sway when he walks. Tsurugi also wears a single black stud in each ear.


Tsurugi states that he has lived at C3 ever since he was born. Yet he remembers when Touma picked him up - he wasn't able to eat, because he had no teeth, and he didn't even know how to drink from a baby's bottle. He was abused by his father and there is no mention of his mother. Touma brought him to the Tsuyuki family where he occasionally raised (most likely by Shuhei's father in C3's HQ) and even celebrated his birthday. When Touma asked about his wish for his birthday, he said all he wanted was a real family - not sweets, toys, money or power - but he also knew this family wasn't his own real family.

When he was around 19, he became partners with Mikuni and Jeje, and shared a room with them. During this time, he received money from Mikuni for doing whatever he was told. Mikuni recalls that when the three of them were together, Tsurugi and Jeje spoke every night.

Tsurugi seems to have been involved with Touma in the past, but more about their relationship has yet to be revealed. It is known that Tsurugi will do anything that Touma orders him to, as a way to pay him back for saving him from his abusive father. When Mahiru sees scars on Tsurugi's upper body, he tells Mahiru he got them from making stupid mistakes while fighting.


Tsubaki and Tsurugi ch 39

Tsurugi attacks Tsubaki.

He appears first in chapter 39 when Mahiru Shirota and co. are fighting against Tsubaki. Tsurugi fights alongside Junichirou Kurumamori and Yumikage Tsukimitsu. Tsurugi corners Tsubaki and is close on subduing him with Yumikage's help, but Kuro stops Yumikage from shooting, allowing Tsubaki to injure Tsurugi's head and then escaped with Higan's help. Afterwards, he introduced himself to Misono whom he recognised as Mikuni's younger brother and notes their resemblance. However, Tsurugi's explanation regarding him and Mikuni makes Misono afraid of him, prompting Jun to tell Tsurugi to stop.

Lawless, Licht, Tsurugi ch 40

Tsurugi convinces Licht to go to C3 HQ by promising to give him lots of melons to eat.

A few weeks afterwards, Tsurugi visits Mahiru's apartment, entering through the window, much to the shock of Mahiru, while Jun and Yumikage enters through the door. They informs the eves and servamps that the three of them have been appointed to become their bodyguards and escort them to C3 HQ. When Licht and Lawless refused, Tsurugi baits Licht into going to their HQ by telling him there are lots of melons that he can eat. After Licht and Lawless gone, Tsurugi and his partners brings Mahiru and Kuro with them for a lunch before going to HQ. After lunch, while on their way to HQ, they received order from Touma to capture nearby subclasses. However, Tsurugi let his bloodlust get the better of him, leading him to kill all the subclasses.

Tsurugi and Jeje ch 44-1

Tsurugi momentarily subdues Jeje.

Back at C3 HQ, Tsurugi meets Mikuni and the waste no time to exchange insults to one another. Situation gets out of control when Mikuni suggests to Mahiru to kill Tsurugi, and Tsurugi takes this as a challenge that he wholeheartedly accepts. He attacks Jeje, throwing him easily to the floor and then easily trips Mikuni. After defeating the two, he turns towards Kuro and inflicts a spell on him that binds the two together, so that the vampire can't seperate from him too much or else he will choke him, much to Kuro's dismay. Mikuni then uses his Lead to strangle Tsurugi, which could have killed him if Kuro didn't cut the rope. Once freed, under Shuhei's order, Tsurugi restraints Kuro when he uses his power to save him. Once Mikuni left, Tsurugi leaves to get something for a moment. After he is back, he frees Kuro from his restraint, apologising for restraining and thanking the vampire for saving him. When Mahiru asks Tsurugi and his teammates to take him to their missions, Tsurugi gives Mahiru Mikuni's old C3 uniform.

Mahiru and Tsurugi ch 46

Tsurugi apologizes to his colleagues.

Second day since Mahiru and the others arrives at C3, Tsurugi becomes Mahiru and Kuro's guardian, almost following them all the time during their stay, sharing one room with them. Tsurugi demonstrates how he always apologies to anyone who is getting mad at him even before they are saying anything and shows no shame in begging to them. He also shows how he has no interest in paper work and instead likes to make the papers into origami instead, which destroys Mahiru's image of how an adult supposed to be. He then tells Mahiru, that he can achieve everything if he apologize properly, a philosophy that Kuro quickly adopts but annoys Mahiru. Being called to the training room, Tsurugi tests new weapon that shot an artificial sunlight on Kuro, changing him into cat. Suddenly the alarm starts - and although C3 calls out it was a mistake, Tsurugi doesn't realize his surroundings anymore and attacks Kuro, pulling Mahiru and Tinker behind him "to protect them from vampire". Jun and Yumikage tries to calm him down, but Tsurugi is still unstable until Tinker stops the alarm. Tsurugi suddenly feels pain on his legs and is taken to medical room where he is approached by Touma. After a short conversation with the vice-manager, Tsurugi states that he will always follow his order.

Mahiru and Tsurugi ch 51-1

Tsurugi restrains Mahiru.

A few days later, several subclasses manages to escape their confinements, leading Tsurugi to go to apprehend them under Touma's order. Mahiru tries to stop Tsurugi from going alone, but Touma orders Tsurugi to restraint the Sloth Pair, which Tsurugi easily does. He is then approached by Jun who also tries to convince him, but Touma orders Tsurugi again, this time to eliminate Jun. With his mind still unstable, Tsurugi tells Jun that he must kill him to protect him, leading the two to fight. Despite Jun's attempt, Tsurugi heavily injures Jun and then goes to chase after the escaped subclasses. He finds Ray and Gil, the subclasses of the Servamp of Wrath and attacks them. A heated battle quickly ensues between Tsurugi and the two subclasses. The subclasses are nearly overwhelmed by Tsurugi, when suddenly the power in the facility cuts out and the communication systems shut down. Unable to receive further orders from Touma, a confused Tsurugi is pushed into the depths of a dysfunctional elevator filled with water by the subclasses. Since Tsurugi cannot swim, he begins to drown the moment he falls into the water.

The Mother and Tsurugi ch 57-3

Tsurugi cries out in The Mother's arms.

The Servamp of Wrath, The Mother, jumps in to save Tsurugi after hearing that the magician is the human whom Lawless and Licht are trying to save. When The Mother saves Tsurugi, the magician has a mental breakdown, crying out that he doesn't want to live anymore and just want to go back to the time before he was born. To calm him down, The Mother hugs him, allowing Tsurugi to let out all of his sadness. When he is considerably calmed down, the ceilings begins to fall down. The Mother protects Tsurugi, trying to escape from the place while carrying Tsurugi, who protests that he doesn't want to live anymore so she should just run and save herself. One of the ceiling hits The Mother, rendering her unable to run because her leg is stuck, but she is able to protect Tsurugi. She tells Tsurugi to escape alone, but Tsurugi refuses, stating that he can't walk alone so he will stay with her. The Mother then suggests that Tsurugi give her a name, but Tsurugi feels inferior about himself as he remembers his past with Touma which further agonised and convinced himself he can't do it.

The Mother shields Tsurugi from the falling debris, saving him though they got trapped inside a rubble as the result. Tsurugi begs The Mother to stop protecting him because no one will come to get him and he feels his life was already happy enough for him, a statement that The Mother rebuffs as a lie. They are freed from the rubble when Touma came to help Tsurugi. He at first thinks that this Touma was another one of his illusion until Touma offers his hand towards him, convincing Tsurugi that Touma is real and thinks that he came to help him because they are like a family. Tsurugi introduces Touma to The Mother and offers her to form a contract with Touma instead because he couldn't think of any name for her, but Touma then shoots The Mother through the chest, shocking Tsurugi.


Tsurugi seems to be very confident and self reliant. He is pretty extroverted calls most of his collegues nicknames with the honorific "-chan". Althogh he states that he only does the work he is paid for, he seems having fun in fighting against Tsubaki.

He also states that he has no pride at all and will do everything for money - he calles him self a shoe licking piece of shit. As long as the price is acceptable, he would work for anyone and do any work. Even if there is no mission, the offers his collegues to do something for money (e.g. perform something) - but they usually turn down his request.

Also - he has a very childish behaviour, and has no interest in paper work (on contrary - he uses to make paper planes out of documents - his explanation is: the more important the document, the better the plane will fly. All of his reports are written in hiragana; he doesn't use kanji (usually only little children use only hiragana because they haven't learned kanji in school yet). When he isn't motivated to do something, he usually won't do it and apologize havily afterwards. The others say, Tsurugi abuses his cuteness to make the others forgive him.

He makes fun of most of his collegues, but he shows deep respect towards Touma and would do everything Touma says - even if it's killing his friends. According to Mikuni, Touma was the one who broke Tsurugi and made his mentality unstable at certain times, which further proven when Yumikage and Kurumamori becomes hostile towards Touma when he approaches Tsurugi.
