From Sneaker Bunko, Volume 1 is now on sale. Volume 2 will be released on August 1st. Currently serialized as a comic in Monthly Shonen Ace. (The comic is based on the book version, not the web version.) About 20 years have passed since dungeons suddenly appeared all over the world. Humanity has gained supernatural powers: levels, stats, and skills. Amane Rin, one of the adventurers who challenges dungeon conquest dreaming of a fortune, has a unique skill, "Dungeon Transfer," which is especially rare even among adventurers, but he has been scorned as incompetent because of its poor usability. However, a turning point comes to him. Exactly one year after starting dungeon conquest—with a level up, his "Dungeon Transfer" evolves. As a result, Rin becomes an existence unbound by the dungeon's rules. Rin, who has become the only special existence in the world, continues to level up at an overwhelming speed, instantly climbing to the top of the world's strongest. This is the story of a boy who was once scorned as incompetent, becoming the world's strongest.
