One Pound Gospel (1995)

Hatanaka Kosaku is a young boxer who has a major flaw he cant stop eating That weakness puts him into into heavier weight classes that put him against stronger boxers and even worse hes prone to throw up when he gets a body blow which drives potential opponents away His coach is at his wits end as he struggles to get this idiot to show some discipline in his training The matter is complicated when a young nun feeds the starving boy after she finds him fainted on the streets during his enforced fast She learns of her mistake and she tries to help him get ready for a fight but his weakness for food and the odd relationship they share dont makes things easy
