Shijou Saikyou no Daimaou, Murabito A ni Tensei suru

A former Demon Lord, known as Varvatos, once lived a life of solitude where others avoided his presence. Seeking companionship, he deliberately reincarnates 3000 years later as Ard Meteor, an ordinary person born in a remote area. Upon returning, he discovers that magic has significantly declined. The average magical abilities he once possessed are now seen as extraordinary talents. As a newly recognized anomaly in this changed world, he embarks on a journey to find genuine friendship.
