Guardian Hearts

Sequel to the madcap Guardian Hearts OVA series, continuing with Kazuya's misadventures.

The story centers on the Platonic Heart, a jewel that — according to an old urban legend — can grant any wish when collected. Only a chosen few are allowed to compete in the Platonic Heart hunt, and high school junior Aya Iseshima is one of 11 girls and women who are taking part.

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!

Originally an April's Fool in 2007, this one episode OVA is a spin-off of the School Days game by 0verflow, and shows Kokoro Katsura, the little sister of one of the main characters, from her other side. A mahou shoujo out to save the world, or something like that.
