Arakawa under the Bridge

Kou Ichinomiya is a perfect man with a perfect life: he is handsome, smart, self-sufficient, and the young heir to a grand corporation. One day, he falls into the Arakawa River and nearly drowns, but is saved by a young girl named Nino, who lives in a community under a nearby bridge on the Arakawa. It's the Ichinomiya tradition to never be indebted to anyone and settle all accounts, and now Kou owes Nino a life debt. Her request is that he becomes her lover and lives with her. And so Kou begins a new life as a member of the village under the bridge - a village, he discovers, full of self-deluded and eccentric people. There's the musician who wears a star mask, a male war veteran dressed as a nun and his femme-fatale rival who runs a farm, a hairdresser samurai and many others, all led by a man in a green costume. Still, as time passes Kou begins to truly feel at home at the Arakawa under the bridge.
