In An event of this series it has been revealed that the series ahs been greenlit for a Second season.
Crunchyroll, Viewster and Funimation streamed the first season. The last one of these describes the story as follows:
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!
I Didn´t watched the first season, but the story sounds hiraliously fun!
