[Mahou 999] no Yuusha Kouhosei, Maou Keiyaku de [Miryoku 999] wo Te ni Ireru

Yuuto, a trainee hero, once devoted his youth to battle with the 【Magic999】 status. After the Demon Lord was defeated and peace restored, his status changed to 【Charm1】, leaving him unimpressed and bored during his academy days. One day, Lilicia, a former Demon Lord with the 【Charm999】 status, appears and offers to swap statuses. Yuuto accepts, gaining 【Magic999】 again and approaching Mekuri, the academy's idol. As he begins to enjoy the academy life he desired, he and Lilicia encounter remnants of the demon race who urge them to return to their original world. Yuuto and Lilicia set out with two goals in mind.
