Ittō-ryū member of great height (over 1.90 meters/6&#039;2&quot; tall). Unlike most members of the Ittō-ryū, Isaku has no weapons to speak of, instead he wears various piece of armor and tends to act defensively. He is also Doa&#039;s best friend and the two always travel together. Isaku often finds himself rescuing Doa, apologizing for her and keeping her from killing others (usually by picking her up and running away). He and Doa have also developed complementary fighting styles, with Isaku acting as the defense and Doa as the offense. He ends up befriending Asano Rin. Is also Christian and was the son of a Christian priest. He is not incredibly intelligent, but is kindhearted. He has been cutted in two as a result of the experiments in Habaki&#039;s compound, only to be reassembled by Doa - he has had similar regenerative abilities to Manji, but lost them after some time has passed.

New adaptation of Mugen no Juunin. 

Damned to wander the Earth in an endless cycle of carnage and murder, the fallen samurai known as Manji seeks the chance to win back his mortality. To do so, he must first balance the deaths weighing against him by slaying 1000 evil souls, a task that would take even the greatest warriors a lifetime. Manji, however, has all the time in the world to kill, and his lonely quest leaves a trail of bloody bodies in his wake… until his path crosses with that of Rin, who has sworn vengeance against the murderers of her family and school, even though the cost will almost certainly be her own life.
