Yaichi "Ichi"
About
It is revealed through flashbacks that Yaichi was actually born as "Seinoshin," a young child who was adopted into a prominent Japanese family, but rejected by his adoptive parents. As a result, he became quiet and withdrawn, with a family servant named Yaichi and Yagi, another heir from another family, as his only friends. He was kidnapped by a bandit named Jin. He believed that Yaichi will protect him but was told that Yaichi was the one who arranged his kidnapping, which traumatizes Seinoshin. When he grew older, Seinoshin worked under the moniker of "Sei" as a bandit and merciless killer of the Bakuro gang. But then for reasons unknown Sei betrayed his old gang, and fled to Edo where he became "Yaichi," forming the Five Leaves gang with a woman named Otake, a woman he paid out of bondage from a brothel. It is later revealed that the original Yaichi did not betray him, forcing Ichi to come to terms with his past.
