Quinx Squad

Known in Japanese as Kuinkusu-han and nicknamed the Qs Squad, this unit answers to the Mado Squad and is staffed only by Quinx. Its members are humans carrying an implanted quinque inside their bodies, a status that sets them apart from ordinary one-eyed ghouls. Each one is treated as a research subject who endured the operation devised by Dr. Kouitsu Chigyou. The group shares a residence called The Chateau in the 1st ward, and for a long stretch their assignments were watched over by Haise Sasaki until he stepped down as their mentor.

Talented as its investigators are, the squad long carried a stigma. Elite units such as the Hirako Squad dismissed them as clumsy and unfit, laying much of the blame on Sasaki. That perception shifted after the Auction Mopping-up Operation lifted their standing, and it climbed higher once the Tsukiyama Family Extermination Operation earned them enough respect to bring in fresh recruits. Their casework traces the wider story: they cut their teeth hunting the killer Torso, then moved through the Nutcracker case, the auction raid, the Rose investigation, the Tsukiyama campaign, the Rushima landing, and finally the siege on the Clowns.

Kuki Urie leads the current roster as mentor and squad leader, with Saiko Yonebayashi serving as his deputy and Touma Higemaru, Ching-Li Hsiao, Yusa Arima, Suzu Sanzu, and Ryuusen Tatsumichi rounding it out. Earlier lineups included Haise Sasaki as founding mentor, the late Ginshi Shirazu as a former leader, and Shinsanpei Aura alongside Tooru Mutsuki. Oversight passed through several hands at the top, among them Yoshitoki Washuu, Kishou Arima, Matsuri Washuu, and Akira Mado. A few details color the group: recruits were paid to accept the surgery, Shirazu cited that money as his motive, and as long as a member's Rc count stays under roughly a thousand they can still stomach human food. Urie, Shirazu, and Saiko all came out of the 7th Academy while Mutsuki trained at the 2nd Junior Academy, and every one of them belongs to the 77th Class.
