Mushoku Tensei

An exceptionally long-lived man who survived until the reign era changed five times. The place he reached after living out his natural lifespan was a new life. Given a second chance, can the old man's life be different this time? Old Man Reincarnation. Beginning now.

Rudeus Greyrat had a twin brother. Eugene Greyrat. He possessed the power to obtain absolutely anything he wanted. Yet, he loved neither his family, the world, nor his very own life. One is a boy trying to live a failed life all over again. One is a boy reborn as a person who is already completely finished. "I will try my best if I go to another world." Those words meant absolutely nothing to Eugene.
