Haise is the mentor of the Quinx Squad which was created to create Ghoul Investigators that could surpass the strongest CCG Special Ghoul Investigator, Kishou Arima.

He has no sense of cooperation, but rather prefers to act alone while looking down on his fellow squad members. He rarely expresses emotions but he does get more jealous than anyone. Kuki’s father is the Special Class Investigator who was killed in duty fighting against the One-Eyed Owl. In order to carry out his plans for revenge, he is fixated on being promoted to the unit his father used to belong to: the S3 Squad.

He has a simple, honest personality and when he is entrusted with things, he is the unexpectedly hard-working type. Beyond his delinquent-looking exterior and his rude speech and actions, is a Ginshi who is thoughtful of his other members. Kuki is his complete opposite and the two are not able to cooperate together, quarreling often.

Tooru Mutsuki

Voice Actor: Natsumi Fujiwara

Birthday: December 14th
Astrological Sign: Sagittarius
Blood Type: AB
Height: 165cm
Weight: 48kg
CCG Rank: Third Class Ghoul Investigator
Tooru is a Ghoul Investigator who adoringly calls Haise “sensei.” In the past, both of his parents were killed by Ghouls and he was subsequently raised by the academy. Tooru is serious, a bit introverted, and hates the sight of blood. Even though he undertakes each investigation seriously, he frequently cannot manage to make them succeed. After undergoing the Quinx medical procedures, his muscles and agility did not appear to increase at all compared to the other members of the squad. This then leads others to view him as being in an immature state. Due to the influence of the procedures though, he now habitually has his right eye covered with an eyepatch. Of all of the members in the Quinx Squad, he has the lowest count of Rc cells, cells found in large numbers within the bodies of ghouls, and he cannot even release his Kagune.

Height: 143cm
Weight: 〇〇kg
CCG Rank: Third Class Ghoul Investigator
Saiko is a NEET Ghoul Investigator who lives her life free of worldly cares by being a hikikomori (shut-in) in the room that she was given. She boasts that she is the creme de la creme in aptitude among her group thanks to the Quinx medical treatments, but because she originally had no plans to become a Ghoul Investigator, she lacks motivation. She is terrible at time management, and even the group leader Kuki has given up on trying to force her to participate in investigative work. Her hobbies include anime, games, manga, and collecting figures among others. She is concerned about her pudgy disposition.
