Hida Kizuna possesses the HHG (Heart Hybrid Gear) ability, but it is not strong enough to make him particularly important. His older sister calls him to transfer to a strategic defense school, where many of the students (many of which are large-breasted girls) use their HHG abilities to fight invaders from another world while wearing extremely skimpy pilot outfits. Kizuna's fighting ability doesn't measure up, but his sister has another plan—apparently having erotic experiences with Kizuna will allow the girls to replenish their energy or power-up. It looks like his new school life is going to be full of embarrassment (Source: MangaHelpers)

Arata chooses the third option: enrolling in the top-secret magic school Royal Biblia Academy. Waiting for him at the academy are seven beautiful magic users, the Trinity Seven, each with her own power and skill. With so many women surrounding him, there are plenty of opportunities to have some silly perverted fun. But it’s not all fun and games for Arata. Spurred on by the memory of his cousin and childhood friend Hijiri Kasuga, Arata will stop at nothing to stop the destruction of the world and bring his best friend back.
