A girl shows up at your door offering sex to a stranger, and the show treats this premise as pure setup for absurdist chaos, not a moral question. The humor lives entirely in escalation and character stupidity, no punchlines that need explaining, no heart buried under the fanservice. It's shock comedy that knows exactly what it is: 80s anime unfiltered, before the medium learned to be careful.

Rokurou is a broke student living in a shabby apartment when a beautiful, mysterious girl named Mamiya Yu turns up at his door. For reasons he cannot explain, she has fallen head over heels for him, perverted habits and all. He soon learns she is the daughter of an extremely rich family and can hardly believe his good fortune, but things are not what they seem: her wealthy relatives prove far more perverted than he ever pictured. Adapted from Yuzuki Hikaru's seinen manga, this single 1987 OVA mixes comedy, romance and ecchi humor.
