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, Eins party members Zoid and Jolene betray him and leave him behind as bait, dooming him to a certain and painful death!

With the artificial spirit eye that Yuri bestowed upon him, and with Ursulas 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. Thats when Yuri asks Ein a certain question...

Ein gains entry to the Forbidden Library of the kingdom. There he meets a girl with a surprising background.

Eins will to protect the village is put to the test with monsters approaching and the true evil revealed.
