Jinbee Tsukishima

The son of a samurai whose father was forced to cut off his own leg in repentance for an incident involving Jinbei and the son of his master, despite not being his fault. When his father is summoned to join Mushibugyou, Jinbei departs to Edo to join the magistrate in his place to make up for his sacrifice and restore the honor of his family. Despite being far stronger than a normal human, Jinbei is the weakest member of the team, making up for his inexperience with determination and an unyielding spirit that ends up earning him the respect and admiration of his peers.
