Eye Patch is a highly energetic old man who is homeless and obsessed with boxing. He references and makes puns to it in almost every single one of his statements. He has a high sense of belief in the youth that they can "become pros". He thinks he can find that potential on the streets, but never does. Additionally, he is good friends with Masurao. Together, they work at restoring Canti and occasionally check in on Tonkichi's work via video call.

Eye Patch has the tone of a wise old man with a deep, gruff voice.
