Everyone Loves Someone!
To the rest of the Defense Club's disappointment, Io and Ryuu got themselves into a little fight. Yumoto, En, and Atsushi excuse themselves to Kurotama while Wombat is left to help Io and Ryuu reconcile, though with no results. The flashbacks show how Io and Ryuu met, showing us they couldn't stand each other at first, and how they decided to join the Defense Club. Kuroshiro Kumano approaches the Beppu twins on how to become an idol, as he would like to become like them.

Cute High Earth Defense Club LOVE! LOVE!
Teenage boys are notoriously lazy, and the members of Binan High School's Earth Defense Club are no exception. Their definition of “earth defense” is bumming around all day at the local bathhouse. But when a pink wombat appears out of thin air and begs the boys to help him save the planet, even the idlest high schoolers jump to action. Watch the magical boys transform and save the earth with the power of LOVE!
