An alien landlord moves onto your roof to turn the world gay, one junior high girl at a time. The premise is absurd enough that the comedy doesn't need to explain itself, it just commits. This OVA knows exactly what it is: a 20-minute joke that doesn't overstay its welcome.

Naoko-san is an alien from the planet Yuri, and she has come to Earth intending to conquer it by making it yuri. She dresses as a maid and has settled in on the roof of Misuzu's house, where the junior high girl living below is forever bothered by her strange new neighbor. Beneath the domestic arrangement, Naoko-san's true aim is still world domination. The single-episode comedy OVA builds its humor around this odd pairing of a scheming alien and the girl stuck putting up with her.
