Hida Reiri is the principal and commander of Ataraxia. She becomes the leader of Ataraxia after it became an independent country. She is the daughter of Hida Nayuta, as well as the older sister and semi-secret lover of Hida Kizuna and adopted older sister Hida Setsuna. Carrying the heavy responsibility of protecting her world from the threats brought by the AU Conflict , Reiri was the one who started the Heart Hybrid program.

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; getting the girls to have erotic experiences with Kizuna, so that it will allow them to replenish their energy or power-up. It looks like his new school life is going to be full of embarrassment!<br>
