After dying in the modern world, Ren awakens as a child in the Naruto universe-alone, powerless, and confused-until a mysterious System activates within him, granting quests, skill upgrades, and access to legendary abilities long thought lost. Armed with future knowledge and a power that grows stronger with every challenge, Ren sets out to rewrite the fate of the shinobi world, carving a path that could lead to salvation-or domination.
