Wizard Boy is introduced as a quick-tempered and irreverent adventurer, displayed when he shoved Priestess aside, yet blamed her for getting in his way. When Goblin Slayer refused to teach him about goblins, Wizard Boy was quick to anger. Wizard Boy is also quite arrogant, repeatedly antagonizing Priestess on more than one occasion; he ridiculed Priestess for failing her promotion exam and disregarded her commands during their following adventure. He does hold his deceased sister in high regard.
