Even Given the Worthless "Appraiser" Class, I'm Actually the Strongest 8

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... With his new "Rex Aura" power, gained while rescuing Yuri, Ein sets his sights on the location of the next World Tree Spirit: Neroguma, kingdom of the anthropomorphs. The kingdom's dragon god is on a rampage and causing the rain to fall without cease...and it's also home to the "Dark Hero" Anfaire?! Can Ein stop the dragon god and find Yuri's sister?!
