Urusei Yatsura Movie 1: Only You

Ataru Moroboshi's talent for attracting trouble finally catches up with a promise he made as a child. Eleven years earlier, he played shadow tag with a girl named Elle and stepped on her shadow. On Elle's planet, that innocent victory counts as a marriage proposal, and the alien princess has now returned to collect her groom.

Wedding invitations spread through Tomobiki before Lum even knows she is not the bride. Furious, she refuses to surrender Ataru, while Elle's people shield him from Lum's electricity and prepare to take him away. With friends, rivals, and aliens piling into the dispute, one forgotten childhood game threatens to become the most chaotic wedding in the galaxy.
