Overview:The whole Deimon team goes to a sports meeting where the team is divided into two teams, Mamori san, Hiruma, and Yukimitsu (the smart team) vs everyone else on the football team (the brawn team). They play tug-o-war and other sports. The "brawn team" finally finds out that Hiruma has plotted all the sports games to teach the team how to do the "bump" in his evil plotting ways by handcuffing everyone's hands (a trick first used by the Taiyo Sphinxes team).
