Urusei Yatsura: Inaba the Dreammaker

Original title: 夢の仕掛人・因幡くん登場！ ラムの未来はどうなるっちゃ？

Directed by Satoshi Dezaki

It is summertime, and Shinobu laments not having a boyfriend. She then happens upon a young man weak from hunger, and wearing a rabbit costume. She gives him a carrot, he expresses his gratitude by hitting on her... and she hits back. The young man leaves behind a key to another dimension where everybody's possible futures exist. Lum and Ataru join Shinobu to find the bunny boy, and happy futures for themselves.
