Reese, Eve

She is a little shy, not being as outspoken as the other characters. Due to being hunted, she is very distrustful of everyone she meets. While not being as vengeful as Setsuna or Keyaru, she nonetheless takes pleasure in killing the demons that killed her own tribe, showing a sadistic smile on her face.

When battling the heroes of Jioral Kingdom, she manages to incapacitate three of them by siphoning their magic and firing a powerful blast of energy at them. However, Keyaru is able to make quick work of her familiars before she herself is defeated. Eve laments her demise as her heart (the Philosopher's Stone) is taken, but Keyaru promises her a new beginning
