1-Pound no Fukuin

Hatanaka Kosaku is a boxer with a powerful knockout punch but struggles with self-control, especially regarding food. He frequently eats hamburgers before fights, which forces him into heavier weight classes and causes him to vomit when hit in the stomach, leading to losses. His battle with willpower becomes more complicated when he meets Sister Angela, a novice nun who attempts to support him. Her efforts to assist him, however, appear to complicate her own religious training.
