One of our protagonists. When he was younger, his father, Ikuse, was killed for what Ichise believes was betraying his friends. A short time after, his mother also died. All he was left with was a vial that contained some of his mother's cells. Soon after, he began his life as a fighter in an underground arena, and proved to be quite formidable. Ichise is very quiet and rarely speaks. He has an odd tendency to go berserk at very inopportune times. Whenever something has angered him, he channels nearly all his energy in an effort to destroy whatever it is that has crossed him. Throughout the course the series, he becomes a little more open, but still remains fairly reserved unless someone directly asks him a question. After one of his fights, he gets into some trouble with Aida, the man who runs the arena. He was rewarded with some cheap sex, but becomes slightly hostile during the love-making. Aida calls up Isshii, a member of Organ, to come and punish Ichise. He does so by lopping off Ichise's right arm. Afterwards, Ichise goes berserk and ends up getting his left leg cut off in similar fashion by Isshii. He manages to get around with a crude crutch, but ends up giving up in despair after he continually has trouble with stairs. Oonishi, the leader of Organ, calls up Doc and tells her that Ichise might be a decent guinea pig for her research. With Doc's 'help', he gets a new Texhnolyzed arm and leg. At first, he abhors his new limbs, but manages. He sees Isshii again and attempts to attack him, but is put down by Isshii's men. He is thrown into the sewers, but manages to escape with the help of Ran. He then spends some time practicing with his Texhnolyze to get the hang of it. He locates Isshii later and manages to beat the shit out of him. He then walks around with Ran for awhile. He runs into Shinji, leader of Lakan, who invites him to Lakan's headquarters. There, he practices the sensitivity of his Texhnolyze. He then leaves and shows up again in the middle of a large confrontation between Organ, the Alliance, and Lakan, where he inadvertantly sets off the spark that starts the war. At the end of the battle, Oonishi brings him along where he eventually stops Yoshii from destroying Lux. Oonishi then includes him as a temporary member of Organ and assigns him to work under Kohagura.
