Apparently, Disillusioned Adventurers Will Save the World, Vol. 3 (manga)

Omtale

Nick and his ragtag band of jaded adventurers have managed to carefully establish a system of rules that can make them all comfortable despite?the scars of betrayal each of them carries. When a party relies on checks and balances rather than fellowship and love, dungeon delving for the legendary trust-powered Sword of Bonds is the last thing you would expect them to do—but that quest just pays too well for Nick and the crew to turn it down! And perhaps this odd group will find that there is more between them than they imagined...?
