Minamikaze Karakara

A boy named Musashi Miyajima is known for loving the word "victory" but hating "effort." Despite being considered a boxing prodigy, he consistently loses matches. After one such loss, he angrily punches a tree, and a girl with feathers falls out. She is the "Goddess of Victory," who has never smiled. She explains she cannot return to heaven unless someone wins for her and makes her smile. Musashi promises to give her that victory. The manga includes seven previously published short stories.
