1-Pound no Fukuin

Hatanaka Kosaku is a boxer with a powerful knockout punch, but he has trouble controlling himself, especially when it comes to food. He often eats hamburgers before fights, which pushes him into heavier weight classes and causes him to vomit when struck in the stomach, leading to his defeat. His struggle with self-discipline becomes even more complicated when he meets Sister Angela, a novice nun who tries to help him. However, her attempts to support him seem to interfere with her own religious training.
