Maou Gakuen no Hangyakusha

Humans are nothing more than slaves for the devil race──.
A normal high school student, Morioka Yuuto was chosen to be a candidate to become the next devil king. He transferred to the academy for devils, GinseiSilver Star Academy where he was held in disdain by other students. 「──I swear I’ll make you the devil king. that’s why……make me your retainer!」 Yuuto’s encounter with a beautiful devil, Himekami Lizel, changed his life and his world. He could learn any kind of magic instantly and absorb magic power infinitely through skin contact with his female retainers. That was a special power that the devil race didn’t have and was only possible for the human Yuuto. The human who became a devil king candidate challenged the strongest devils in order to become the devil king of justice!
Exhilarating and fascinating. This is the beginning of the story about climbing up the ranks in the magic academy!
