Hayuru is the ace of Japan and an esteemed member of the Amaterasu. She is a member of Ataraxia's Morals Committee and an extremely strict woman.

Hayuru is a beautiful young woman with long eyelashes and blue eyes. She has long black hair with hime-style which is decorated with red ribbons, that keep her hairstyle into twin-tails. She has a slender figure yet Hayuru does have well-developed bust and voluptuous buttocks. Furthermore, she wears the usual academic uniform. In privacy, she sometimes wears a headdress with cat ears.

Her Neros looks like a device that gives the image of a sharp bladed tool. An armament that looks similar to a Japanese katana is fixed at the waist, while eight long and slender mechanical parts float on her back. In other words, she looks somewhat like a samurai from the Edo period, which is reflected by her personality.

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>
