After 10 Years, I Returned to Find Myself the World's Strongest Unknown

by Kanzaki Subaru

At fifteen, Kurose Ren lost his parents in an accident. Wandering into a cave he'd stumbled upon by chance, he found himself sealed inside the world's first dungeon. What he gained there were 《Infinite Growth》, a skill with no limit to how far he can develop, and 《Survival Adaptation》, which reshapes his body to keep him alive. Carrying nothing and knowing nothing, a fifteen-year-old boy battles monsters and endures a brutal environment, growing little by little as he survives. And then, ten years. At the end of that long dungeon life, Ren reached the very strongest. With the dungeon fully conquered, he finally returned to the outside world at twenty-five. What waited for him there was a world greatly changed in ten years, and Mizuki — the childhood friend he was seeing again for the first time in a decade. Together with Mizuki, Ren sets about reclaiming the ordinary days he lost. This is the story of a man who never wanted to be the strongest, enjoying his ordinary days in a world ten years unfamiliar, while slowly coming to face his own power and the secrets of the world. ※ Part 1 follows fifteen-year-old Ren, who starts with nothing, as he survives the dungeon over ten long years on his way to becoming the strongest.
