Warrior and Fighter came from the same village. They had quarreled on the journey an uncountable number of times. Fighter was horrified when she witnessed his brutal death.
Although their time together was limited, they presumed to be on good terms, as they're are in the same party without any problems. In their first and final mission, Warrior was shown to care for Wizard's well-being, as he immediately comes to her rescue and kills off some of the goblins when hearing her scream in agony from being wounded.
Like Fighter, Warrior was very welcoming towards her (believing that they needed a priestess in their party). When she expressed doubts about their chances without any preparations, he proudly assures her that the mission would be a cakewalk.
