The appraiser Ein is exploring a dungeon with his party, who keep mistreating him and call him "trash picker." As they venture further, they get swarmed by a pack of strong monsters called Hell Hounds. In order to survive, Ein's party members Zoid and Jolene betray him and leave him behind as bait, dooming him to a certain and painful death!
In a world where heroes are born, not made, Ein’s god-given gift is the weakest: the power to appraise things. Treated cruelly by his peers, Ein spends his days in self-abasement—until he meets Yuri, the spirit of the World Tree. Yuri and her protector, Ursula, bless Ein with the Spirit Eye, unlocking new strength. As his abilities grow, Ein embarks on a journey to uncover his true purpose.

Ein manages to survive his plunge thanks to the help of a mysterious power, but even greater dangers await him in the depths of the dungeon. Can he master his newfound abilities and attempt to make an escape?
With the artificial spirit eye that Yuri bestowed upon him, and with Ursula's training, Ein has gotten stronger. When he sets his sights on reaching the surface, Yuri asks him to take her with him.
