Sekigan Renkin Kenshi no Yarinaoshi Kitan

Five years after dungeons appeared on Earth, the prodigious explorer Yoichi Yashiro was at the top. But a battle with a powerful, irregular monster cost him an eye and his ability to see magic. Cast out and branded a failure, Yoichi fell to the lowest rank. Yet, he never gave up. In place of his lost sight, he awakened the “Abyssal Eye,” a unique power that lets him sense the true structure of the dungeons and the weaknesses of his enemies. This is the story of his counterattack from rock bottom, using a one-of-a-kind power to fight his way back to the top and uncover the world’s secrets.
