The official site for light novel Masou Gakuen HxH (Hybrid x Heart Magias Academy Ataraxia) announced that the series will receive an anime adaptation. The format of the anime has yet to be announced.

The series is written by Masamune Kuji and illustrated by Kurogin and Hisasi. The light novel has been publishing since February 2014 and is currently ongoing with five compiled volumes. In June 2015, it received a manga adaptation that is being serialized in Comp Ace magazine.

A drama CD went on sale in March, and it features the voices of Ayaka Kimura, Hikaru Isshiki, Ichigo Momoi, and Rino Kawashima. It is unknown whether they will reprise their roles.

Synopsis
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! (Source: MangaHelpers)
