Machiko Washio

A curse placed on Lum as an infant manifests itself in the present day, causing her to be taken to another dimension. Lum's husband, Ataru Moroboshi is turned into a hippo, and attempts to find Lum with the help of her friends.

Lum doesn't need much assistance going ballistic when everyone in Tomobiki gets an invitation to Ataru's wedding -- and she's not listed as the bride! It seems that some 11 years ago, Ataru played Shadow Tag with a young girl named Elle and won. Unfortunately, Elle was yet another Alien Princess; and on her planet, if a boy steps on a girl's shadow, they have to marry.

Lupa, yet another one of Lum's fiancés, arrives on the scene, and Lum and Ataru have to repeat their game of tag in order to prevent the Earth from being destroyed.
