–Kinichi Tohyama (Kana)
Kinichi Tohyama (Kana) (遠山 金一 Tohyama Kin'ichi) is the older brother of Kinji Tohyama and genetic older brother of Kinzou Tohyama (GIII) and Kaname Tohyama and eldest sibling of the Tohyama family. He is also a former member of IU, which is later revealed to be a cover he took to destroy the organization. Kinji has always idolized Kinichi and has viewed him as his ideal throughout his life. As such, Kinichi's presumed "death" before the events of Volume 1 is one of Kinji's major motivations for attempting to transfer out of Butei High and quit being a Butei altogether. Often times Kinji has to correct himself when addressing Kana, as she does not respond to "Nii-san."
Kinichi when he cross-dresses as Kana has long braided brown hair, wears the female Butei uniform, and wears long black stockings.
Kana is the eldest son of the Tohyama Family and graduate of Tokyo Butei High. He oversaw the training and raised Kinji after their parents died. It was through overseeing Kinji training and distress he felt with Hysteria Savant Syndrome that Kinichi began to tinker with alternative ways to trigger or repress it. Thus, he developed the character of "Kana" and managed to trigger HSS through means of cross dressing.
At an unknown point in time, Kinichi joined IU as a double agent in order to bring the organization down. To make it seem like he was a genuine member, he participated in the organization's missions and shared the secrets of his HSS. In one more infamous case, he was a part of the special operations team that destroyed the Mamiya Family's household because they refused to cooperate with IU. Perhaps as a way to prevent Kinji from getting involved, Kinichi took a Butei assignment to save the passengers of the SS Annabelle. Following the evacuation of the passengers, Kinichi faked his own death by sinking along with the ship.
In the time he would spend dead to the world outside of IU, he would come to regret what he did as he did not count on the media backlash Kinji would suffer in the stead of his brother that was labeled a failure. He continued to operate with IU while monitoring Kinji from the shadows. Also at some point during his tenure, Patra fell in love with him and he also harbored feelings for her.
