Mushoku Tensei: Jobless Reincarnation

After 34 years of being bullied, unemployed, and shut away from the world, a nameless man finally tries to do something heroic — and it costs him his life. He wakes up as a newborn baby in a world of swords and sorcery, given a rare second chance he never thought he'd get. Keeping every memory and regret from his old life, he's reborn as Rudeus Greyrat, determined this time to live without holding back.

With the mind of a grown adult and none of his old hang-ups, Rudeus throws himself into learning magic under the tutelage of Roxy Migurdia, a gifted young mage, while training in swordsmanship under his father, Paul. Along the way he befriends Sylphiette, a girl his own age who becomes his closest companion, and slowly starts building the kind of life, family, and confidence he never had before.

Part 1 covers Rudeus's early childhood and adolescence in the Fedoa Region, following his growth as a prodigy in magic, his first real friendships and rivalries, and the events that set him on the path toward a much larger, more dangerous world.
