Urusei Yatsura

Ataru Moroboshi is a mischievous, girl-crazy high school sophomore living in the quiet town of Tomobiki. His life takes a wild turn when an alien race called the Oni invades Earth. By accident, he ends up proposing to Lum Invader, the Oni princess, instead of his crush Shinobu. Now stuck with Lum as his unwanted fiancée, Ataru becomes a magnet for all kinds of alien visitors, turning his life-and the lives of his friends-into constant chaos. His already shaky reputation takes even more hits as bizarre encounters pile up.
