A Rampage on a Cosmic Scale!

Synopsis

Yousuke's famously strict mother is a collector of perfect-score tests. Today, too, she's eagerly waiting for the test he'll bring home. Unfortunately, Yousuke drops the test on the way back. To prove to his mom he didn't lie about getting a perfect score, he goes searching for it. Just then, Kotaro reports that a demon beast is on the loose — making things around town grow huge. Yousuke's test is one of them: now the size of a building, on display for everyone to see. Embarrassed out of his mind, Yousuke takes Gekiryuger to try to ferry the giant test home.
