Akagawa Chiyomi, his family was brutally massacred (Lame idea, I know..) by the opposing clan when he was 10 years old. He escaped with his little brother and live in a temple with an old monk after the sacred man found them unconscious near the stairs to the temple.
Chiyomi and Chisaku trained to be perfect fighter since the old monk used to be a well-known assassin.
Day by day, Chiyomi's heart darkens by vengeance and he failed to think logically like Chisaku.
Even after they killed the head of the opposing clan, Chiyomi never satisfied. He was filled with the desire to kill and he cross the limit when he killed his own brother and the old monk.
Up until today, he was still hunting for innocent souls, intended to feed his bloodlust desire....
