Shijou Saikyou no Daimaou, Murabito A ni Tensei suru

Having reached the pinnacle of human potential, Varvatos was so powerful that the rest of humankind began calling him the Demon Lord, both fearing and respecting his overwhelming influence. As a result, he felt alienated from his fellow humans, leading him to desire true companionship—an equal he could call a friend. Hoping his fate will change in his next life, Varvatos decides to start anew and reincarnates three thousand years later as Ard Meteor, the son of a seemingly ordinary couple in a rural town. Unfortunately, he realizes that even after weakening himself, his strength still overshadows everyone in this era. Moreover, his lack of social skills bars him from achieving his goal of making friends. But worst of all, the repercussions of suddenly abandoning his former position have begun to bite him back in some of the most unimaginable ways possible.

But Ard has a one-track mind, and he wont stop at anything to achieve his ultimate goal
