Ningen Fushin: Adventurers Who Don't Believe in Humanity Will Save the World (2023)

One day, Nick, an adventurer with a wealth of experience, was framed for embezzlement and expelled from his party by its leader. Thoroughly depressed, Nick went to a bar to drink away his sorrows when he found companions in a former noblewoman, an excommunicated priest, and a female dragon warrior: all adventurers who had been betrayed and could no longer trust others. Precisely because they all knew the pain of being betrayed, they decided to team up as a party to earn a living.
