Danpei Tange
Danpei is Joe’s serious, cautious and responsible mentor who gets him started in his boxing career. He is fond of sake, being overly cheerful when drunk which contrasts with his strict everyday self. He is also very polite when talking to people that hold higher ranks than himself, something that annoys Joe, who doesn’t care for such things.
After meeting Joe and claiming that he has massive potential for the sport, he gives up on drinking due to the former’s aversion to alcoholism (only drinking on special occasions) and vows to train him to be Japan’s or even the world’s best boxer, with the hope of a better tomorrow for the both of them.
