Yasui Yagami, a highly skilled explorer who had been tackling dungeons from the very beginning and was expected to have a bright future, was attacked by an irregular “Trial Monster.” In order to save his team members, he sacrificed his vision in one eye, leaving him one-eyed. As a result, Yai was branded a failure, but he had no intention of giving up on his life as an explorer! *“No matter what happens, I have no intention of quitting as an explorer. And I certainly have no intention of ending up a loser.”* The path Yai chose was a new fighting style that compensates for his lost combat power by utilizing various items found in dungeons!? Will Yai prove his true worth in a rematch against the Trial Monster— The man who was thought to be unable to fight after losing an eye—the power he attained through sheer determination is that of an Alchemy Swordsman! A dungeon-dominating fantasy where a one-of-a-kind power mounts a counterattack from the very bottom! (Source: Hobby Japan, translated)
