Tsuihou Sareta Shounin wa Kin no Chikara de Sekai wo Sukuu

Torao works as a merchant, a role few respect, within an S-rank adventuring party. Unremarkable in a fight and eventually caught siphoning off the group's money, he is dismissed on the spot. With nowhere else to turn, he joins up with the girls he spent the stolen funds on and sets his sights on bringing down the Demon Lord. Their very first assignment, however, turns out to be stripping gear from the bodies of the former comrades who cast him out.
