Apparently, Disillusioned Adventurers Will Save the World: Season 1

Misfortune hits Nick when he’s fired from his adventurer party and dumped on the same day. Needing new partners, he drowns his sorrows at the local tavern, but sees betrayal everywhere.

He catches a break when he chances upon other jaded souls sharing their tales of treachery. Wait! They can form a new party, united by their hatred of humanity.

All they’ll need is to trust each other—good luck!
