The Misfit of Demon King Academy 1 (Gangan Comics UP!)

[Machine Translation] A reincarnated demon king rises up the hierarchy of the demon tribe! Tired of the endless struggle, destroying people, spirits, and even gods, the tyrannical demon king Anos was reincarnated, dreaming of a peaceful world. However, 2,000 years later, what awaits him are his descendants, who have grown too weak and accustomed to peace, and his magic, which has deteriorated to the extreme. Anos enrolls in the "Demon King Academy," a school for reincarnated Demon Kings, but the academy fails to recognize his power and brands him a nonconformist. While he is underestimated by everyone, he adds Misha, the only girl who is kind to him, to his crew, and the nonconformist (Demon King) rises up the hierarchy of the Demon Tribe!
