Even Given the Worthless "Appraiser" Class, I'm Actually the Strongest 9

In a fantasy world where "jobs" are god-given from birth, heroes are born, not made...and Ein's job of "Appraiser" has put him about as far from the "hero" pedestal as possible. Used, abused, and eventually abandoned by his fellow adventurers, Ein decides it just isn't worth going on... Lucky for Ein, though, the end may just be the beginning...and a new lease on life. Turns out, his "worthless" job may just be the key to becoming a hero after all... Ein and the gang have come to Kai Pagoss, the kingdom of ice and snow, in search for another one of the spirit sisters. But when they arrive, they encounter a man calling himself "Ein Rayshik"...and who's enslaving the dwarf population?! To make matters worse, the dwarves and their spirit protector have been forced to endure harsh conditions under the demons who have come to exploit the power of Demon God Torr, who's sealed away in the nearby World Tree Hall. Can Ein free the dwarves and stop the resurrection of Demon God Torr??
