J.J. George

J.J. is a national boxing champion with a very high opinion of himself.
He is evidently, a large African-American. J.J. George claims he is quite literally "a champion" and that he is "the strongest". He is supposedly married, and has several children.

J.J. George speaks very little Japanese.

He is racist towards the Japanese but comes to regret it when he is soundly defeated by Momotarou.
