Tatsumi Leonard Aragaki

Nanbu's former student. He was called up for military service a few years before the start of the story, during his time as a soldier he was directly hit by an explosion which cost him his legs and burned half his face off. When he returned home he started to suffer from PTSD which led him to attempt suicide and he also felt abandoned by Nanbu after finding that he had closed down his gym when he thought Aragaki had died. He makes his return to Megalo Boxing 3 years before the start of the story and fights his way up to rank 17, when he hears that Nanbu has a new popular Megalo Boxer named Joe he vows to destroy him so that Nanbu can feel his pain, but he also wants to earn money from sponsors so that he can repay everyone from the veteran's association for giving him his life back.
