Kartein is a prideful, talented healer, confident in his abilities. He often refers to himself in the third person to boast. He trusts Kayden and Jiwoo but refuses to heal without payment. Pluton prides himself on his strength, often comparing himself to Kayden. He claims credit for Kayden's reputation and gets frustrated when he can't master a skill quickly. Kayden is a passionate fighter, once a brash loner who refused disciples. Meeting Jiwoo softened him.
