Apparently, Disillusioned Adventurers Will Save the World, Vol. 4 (manga)

Nick and his party have conquered the labyrinth and claimed the holy Sword of Bonds—just about the last thing you would expect of a group brought together by their pasts full of traumatic betrayals! But maybe, just maybe, the party can come to trust each other at least a little bit and to heal the scars of their histories together…That is, if a chance encounter with Claudine, the wicked woman who duped Nick, doesn’t reopen old wounds first!
