That’s not entirely unreasonable…”“No, a personal paradise.”“A private—wait!

After 2000 years has passed, the ruthless demon lord has just been reincarnated! But his aptitude at an academy for nurturing candidates for demon lords is, “Inept”!?

Having the capability to destroy humans, elementals, and gods, after a long period of countless wars and strife, Arnos the demon lord became sick and tired of all that and longed for a peaceful world, so he decided to reincarnate to the future.

However, what awaited him after his reincarnation is a world too used to peace that his descendants became too weak due to a huge weakening in magical powers.

Arnos enrolled in the Maou Academy established to find any students that might be the demon lord’s reincarnation, but his powers are too extraordinary that those in the academy couldn’t properly judge his powers, so he’s regarded as an “Inept student”. Being underestimated and avoided by most people there, he recruited a girl friendly to him, Misha, as his subordinate and comrade, and strives to climb to the top of the demon race hierarchy to one day reclaim his former title and status.

Being dragged forcefully, the young man found himself in a world where cultivation and magic exists. In this vast multi-worlds, the blood of the innocent and the blood of the guilt are spilled like it's nothing.

“I finally found you,” The words sent a jolt to his soul as an unknown yet familiar blurred memory played in his mind. Embraced by the unknown woman, they shared a kiss to his surprise.

Wearing a ring that held half of the power of his past life, the young man ventured to find his women and retrieve his lost memories.

Oh yeah, he was transferred naked.
