"Sa*ra-so" is an old apartment in Kita-Shinjuku that does not have a bath these days. A very naughty daily life of a naughty beautiful girl "Eri-chan" who lives in room 110 there. A virgin, a salaryman who doesn't care, an old man who lives in the same apartment... Eri-chan, who gets lustful in the bath, picks up a man on her way home from the public bath and brings her into her room, day or night.
