In the third Urusei Yatsura movie Remember My Love, a boy possessed by an evil curse travels back in time to protect Lum's innocence by separating her from Ataru. Now imagine that boy actually moving back in time into the universe of The End of the Circus, where the history of Moroboshi Ataru/Tariko Katabarbe is much different than he was taught...!

Urusei Yatsura & Sister Princess crossover, based on a slight variation on The Senior Year storyline. First of an unknown number of stories. Six weeks after Tag Race Two, Ataru returns to Tomobiki ready to divorce Lum! And she agrees!
