An extraterrestrial visitor from the planet Yuri has taken up residence on Misuzu's rooftop with a singular mission: transforming Earth into a yuri paradise. Misuzu, a junior high girl, is constantly bothered by Naoko-san, the alien living on top of her house. When rumors spread that a molester is prowling the area, the two of them decide to look into it together. The OVA is a gag comedy adapted from Kashmir's surreal manga, and it plays its outlandish premise of an alien invader bent on yurifying the planet for laughs, drawing its humor from the pairing of the scheming Naoko-san and the long-suffering Misuzu.
