Gantetsu

Gantetsu is a former Shinobazu, or criminal ninja. While he was a member of the group, he began to feel guilty for what he was doing and saved the children from the houses they razed, hiding them in the Forest of Bewilderment with some of the money that he stole. Despite this, he knows that he can never completely atone for his crimes.

Gantetsu is captured and to be taken to a local capital city. On the trip down a river, his comrades attack a prison ship; while it is initially thought they are planning to rescue him, they are looking for him in order to find the money that he hid away. Although Todoroki does not trust him, and tries to kill him on more than one occasion, Gantetsu repeatedly helps the group navigate the forest and defeat the Shinobazu members, even saving Todoroki's life. Todoroki agrees to falsely report that he had died in order to allow him to remain with his orphans.
