Binan Koukou Chikyuu Bouei-bu LOVE!

Synopsis

Binan High is preparing for their Culture Festival. Since the class or club that win the popularity vote receives a cash prize, the Defense Club will participate as well. They decided to serve Atsushi's curry and transform into their Battle Lover costumes to sell "Cosplay Hero Curry." On the day of the Culture Festival, when Kinshiro follows the smell of curry that's drifting into the student council room, he finds Atsushi transformed as Epinard in the Defense Club room, learning his secret identity. Being fueled by spiteful memories, Kinshiro transforms into Aurite, and the fated battle between the Battle Lovers and Caerula Adamas begins. (Source: Wikipedia)
