Rei is an S rank Hunter . She's the sister of Ashe ,an S rank Sorcerer woman , and of Lihan , a male B rank warrior. She's very close to her gentle sister Ashe and very protective of her little brother, Lihan. Ashe and Rei are two of the most powerful people in their guild and they both try to raise Lihan to that same status by going with him on lower ranked missions. The three of them always stick together. Ashe is sharp tongue and somewhat rude but she's caring and has a very hidden soft side.
