Urusei Yatsura

Ataru Moroboshi's legendary bad luck reaches a planetary scale when alien invaders choose him to represent Earth in a contest against Lum, their beautiful horned princess. He wins the game of tag, but a badly timed remark convinces Lum that Ataru intends to marry her. She accepts enthusiastically and installs herself in his home before he can explain otherwise.

That single misunderstanding destroys any hope of an ordinary adolescence. Lum can fly, fire electricity, and attract relatives and aliens whose problems routinely land in Tomobiki. Ataru remains hopelessly interested in every attractive woman he sees, while childhood friend Shinobu is caught between anger and disbelief. Love triangles quickly become polygons, science and folklore collide, and the town learns that when Ataru and Lum are involved, even a minor argument can escalate into a public catastrophe.
