Maison Ikkoku - Season 0 Episode 2

Released in 1990 this 30 minute special is the only 'true' OAV in the series. This is a completely original piece of animation. The story is based on the extra chapter of Maison Ikkoku where the tenants and Mitaka are all shipwrecked on a deserted island due to the usual insane partying by Ichinose, Akemi and Yotsuya. Once they are on the island Kyoko begins sweeping the sand to keep herself busy while Godai and Mitaka compete with one another to catch fish for Kyoko and make sure she doesn't starve. All the while Yotsuya wanders off by himself and finds a nearby resort, where he makes himself right at home, never telling his other castaways of course.
