Holding strictly to his family's creed, Kou Ichinomiya has never once, in his life of privilege, owed anything to anyone – that is, until a self-proclaimed Venusian named Nino saves him from drowning in the wake of a dire accident involving Kou's pants. Eternally indebted to the supposed extraterrestrial, Kou moves into her little community under the bridge along the Arakawa river. Ripped from his life of luxury and success, the young Tokyo U graduate now must adjust to his well-appointed hovel, strange new neighbors, and peculiar lover, Nino.
If you liked Arakawa's weird yet enjoyable characters then you would like to watch Welcome to the NHK! (or vice versa) because both series have some cracked and unique characters who are living isolated from the society. Everything they do is extreme yet you get used to it while wathing these series.
