Sekigan Renkin Kenshi no Yarinaoshi Kitan

Five years have passed since dungeons suddenly appeared on Earth. Yashiro Yoiichi—a highly skilled explorer who challenged dungeon raids from the very beginning—was once seen as a rising star. But during one expedition, he was attacked by an irregular monster known as a “Trial Beast,” losing the sight in one eye. Branded a failure and cast aside as a washed-up explorer, Yoiichi refuses to give up. Armed with a unique power unlike anything else, he rises from the very bottom to strike back. A dungeon-dominating fantasy about a one-eyed alchemist swordsman’s comeback!
