Urusei Yatsura: Deadly! Standup Eating Wars!!

Overview

Megane deals with a tough, fast-eating "fast-food costumer dragon" named Ryuu at the noodle shop he works at, who criticizes others' inferior foods and eats for free if not satisfied. 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 fast-food fighters to determine if Tomobiki gets the supermarket.
