Ataru's parents head away for an overnight trip to Atami, leaving Lum and Ataru in the house together. Ataru dreads the prospect of a Lum-cooked dinner, while a horrified Mendou and Lum's Stormtroopers storm the Moroboshi home to protect Lum from Ataru. Ataru tries to kiss her at the last moment, but as a precaution, puts an armor that prevents electricity, in the last frames ... he begins to cry.
