魔装学園H×H

あらすじ

Hida Kizuna wields the HHG (Heart Hybrid Gear) ability, yet his power is too weak to make him stand out. His older sister urges him to transfer to a strategic defense school where students, many of whom are large-breasted girls, utilize their HHG abilities to battle invaders from another world while clad in extremely skimpy pilot outfits. Although Kizuna's combat skills fall short, his sister devises an alternative strategy: having the girls engage in erotic experiences with him to replenish their energy and boost their power. Consequently, his new school life promises to be filled with embarrassment!
