A 34-year-old shut-in (NEET) dies after saving a group of teens from a speeding truck. But death isn’t the end—he awakens as a baby in a fantasy world filled with magic, monsters, and medieval kingdoms. Retaining all his memories, he vows to live this new life to the fullest, free of the regrets that haunted his previous existence.
Reborn as Rudeus Greyrat, he quickly shows an extraordinary aptitude for magic. His parents, Paul and Zenith, hire the mage Roxy Migurdia to train him, and from there, Rudeus begins a journey of self-discovery. He meets friends, mentors, and rivals, each shaping his path—from the shy Sylphiette to the fiery Eris Boreas Greyrat, with whom he shares a turbulent but transformative relationship.
But the world isn’t safe. A mysterious teleportation disaster scatters people across the globe, forcing Rudeus into survival mode. As he matures, he confronts trauma, love, loss, and the consequences of his choices. The story spans years, evolving from childhood innocence to adult complexity, with Rudeus striving to become someone worthy of the second chance he’s been given.
