Maou Gakuin no Futekigousha

After two millennia of slumber, the merciless Demon King awakens once more, reborn into a new era. However, his evaluation at an elite academy designed to train future demon lords labels him as “Incompetent.” Arnos, a being of unimaginable power capable of annihilating mortals, spirits, and even deities, had grown weary of endless conflict. Having endured countless battles across the ages, he sought respite from the ceaseless bloodshed. Desiring tranquility, the mighty Demon King chose reincarnation, hoping to find peace in a distant future. Yet destiny has other plans, thrusting him back into a world that still trembles before his might. Now, despite his supposed shortcomings, Arnos must navigate this unfamiliar time while concealing his true nature. The academy, unaware of his identity, becomes the stage for his new journey—one where the past and future collide in unexpected ways.
