Cute High Earth Defense Club LOVE!

The Earth Defense Club at Binan High School is a group of boys who do nothing but be lazy. One day, two of the club members, Atsushi and En, are taking a bath at a bathhouse when a talking pink Wombat appears out of nowhere and asks the two boys to help save the Earth with the power of love. Unfortunately, the bathhouse owner's son, Yumoto, sees the wombat and chases after it, saying "Let me fluff you up!". The next day, the two boys and the other two club members, Io and Ryu, are met by the pink wombat, and suddenly bracelets appear and clasp onto the wrists of all four members, as well as Yumoto (who just happened to be nearby),and they are transformed into the Battle Lovers.
