Onihei Gaiden: The Night Rabbit.

Bandit leader "Night Rabbit" Kakuemon has always kept the rule to "never kill, never rape, never steal from the poor", passed down to him by the gang's previous leader. He has never been arrested, and for that, he always thought he would have a peaceful death. But one day, after talking to a young one-armed homeless girl, he decides to break up his gang and turn himself in.
