Even Given the Worthless "Appraiser" Class, I'm Actually the Strongest

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!

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. To that end, Ursula further enhances both his eyes, and they are ready to leave. That's when Yuri asks Ein a certain question..

In search of Yuri's sisters, Ein enters a dungeon that Jasper told him about. This hidden dungeon is just full of traps. But what is Zoid doing here?!

Pina and Kurohime join Ein. Soon after, guild master Meegan gives Ein an SS-rank quest to defeat the Behemoth.

Ein doubts that any of his feats were due to his development. Meanwhile, a monster attacks Yuri and Pina.
