Plot
The protagonist of the series is Kōsaku Hatanaka, the pride of Mukōda Gym for the most part. He went pro in only two bouts after leaving high school, and his strong punches are universally recognized by his opponents. While he is a natural at boxing, he can't control his voracious appetite. Not surprisingly, Kōsaku eats anything and everything. As a result, he has been forced to change his weight class since high school. Going from flyweight, all the way up to feather weight, something his trainer tells him he doesn't have the frame for. On top of this he accepts challenges from higher weight classes, giving his coach (and himself) constant trouble.

Into this picture steps Sister Angela, a novice nun who takes Kōsaku on as a personal project, determined to set him on the right path and break his habit of gluttony. She constantly encourages him, making sure that he stays in shape while staying away from food. Unfortunately, closeness can sometimes breed feelings of affection, which Kōsaku begins to develop. Even worse, Sister Angela realizes she is beginning to have the same problems as well.
