A batch of matsutake mushrooms from Cherry turn the Tomobiki High student body and staff alike (except Lum and Cherry himself) into a bunch of high weirdos desperate for entertainment.

After Ten burns Lum's scarf she made especially for Ataru, he's forced to do something he's never really done before - apologize. And Ataru is making sure to drag this out as much as possible, even convincing Lum to get angry at him.

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 Mendo and Lum's Stormtroopers storm the Moroboshi home to protect Lum from Ataru.

But soon other fast-food fighters start hitting the scene in Tomobiki, and Megane only worries even more. Turns out that Mendou, who's thinking of opening a supermarket in town in an attempt to bankrupt the small-time family restaurants, is the cause of this, starting a contest between Ataru and co. and the
