That's Dirty---!

Overview

Kenji wakes up after being hit by the zipper from Takao's old uniform to discover that he's locked in a thumb war with Shio as a semifinal match. Meanwhile, Takao and Roka are locked in a game of musical chairs, but seem to have forgotten the chair entirely and are instead tackling each other. The Grand Final round turns out to be a "King's Game," but with only two people the winner is whoever picks the "King" stick.
