From Wikipedia: Enno Ozuno, Master of the Enno temple used the demon guardian spirit Zenki to defeat the demon goddess Karuma. After defeating Karuma, he later sealed Zenki away in a pillar until needed again. Centuries later, his descendant, a school girl named Chiaki Enno (役 小明, Enno Chiaki, or Cherry Night in some dubs) is able to free Zenki, although the demon currently has the form of a brattish demon child. To transform this extremely defiant demon into the form that made him useful by her ancestor, she uses a bracelet that appeared on her wrist when servants of Karuma broke the seal that imprisoned a seed of Karuma. Zenki appears because the seeds of Karuma (which look like eyeballs) start appearing and turning people into monsters and Zenki needed again to eradicate this menace.
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.
