A single-family home left behind by deceased parents. Hikari decided to renovate it slightly and start managing an apartment building. There's a drunkard tenant who doesn't pay rent, a 10-year repeat college entrance exam failure virgin, a tenant confined to home rest due to an accident, and someone peeking at masturbation in room 102... 'Maison Ikkoku' is a story where various problems with tenants are solved using a K-cup voluptuous body.
