Binan Koukou Chikyuu Bouei-bu Love! Love!

With their last cosmic battle behind them, the Earth Defense Club happily returns to doing what it does best: relaxing at the Kurotama Bath and avoiding anything that resembles responsibility. Their peace ends when the Love Bracelets call them back into action and a new wave of monsters begins targeting Binan High.

Behind the attacks are the Beppu twins, Akihiko and Haruhiko, performers whose obsession with attention and affection makes the Battle Lovers their perfect rivals. As graduation approaches for some members of the club, the boys must face a conflict that tests not only their transformations but what their strange friendship will look like after school life changes.
