Summary:
Kokuryuu Kaguya was only a little boy when he witnessed his father murdered by demons. He spent years trying to convince people about what he witnessed, but was dismissed as a traumatized child with an over-active imagination. Now a teenager, Kaguya still remembers what happened. One day, Kaguya is struck by a mysterious light and meets a young girl named Mao—a skillful warrior wearing bunny ears—who rescues him from a demons' attack, then demands to know what planet he's from! Kaguya finds himself inducted into a secret organization of other-worldly individuals whose goal is to defend Earth from monstrous invaders. Reborn as a Battle Rabbit, strange powers awaken within Kaguya which allow him to fight these creatures and seek vengeance for his father's death.
