Tatsumi Leonard Aragaki trained under Nanbu back in the day. He's a Megaloboxing coach now, running things at a gym that caters to retired veterans—a role that suits him, given his own history.
He wears prosthetic legs following a war injury that left deep scars, both physical and psychological. A brutal fight against Joe became a turning point for him, forcing him to finally confront the trauma he'd been carrying. That match seemed to crack something open in him, and he's channeled that reckoning into his work training the next generation.
