In Monea, a young wizard named Zeo discovers himself amidst a group of misfit adventurers led by the beautiful priestess Tia. Although Zeo initially has no desire to join forces with other travelers, circumstances force him into doing so. As he becomes more involved in their quest, Tia expresses interest in making him an ally. However, she soon learns that her intentions are not what they seem.
Tia is determined to hunt down the wizard and summoned demon responsible for destroying her town and family. To achieve this goal, she plans on first calling forth the demon. The problem is that demon summoning magic is strictly prohibited and punishable by death. Tia recognizes that she needs a skilled wizard to assist with the ritual, and Zeo's presence in their group makes him an ideal candidate.
However, little does Tia know that Zeo already possesses his own illegal demon companion, which is why he was so adamant about adventuring alone initially. As Tia becomes more aware of this secret, she must decide whether to trust Zeo or turn against him. Will Zeo be willing to help her with her quest despite the potential consequences, or will his guarded nature lead to his execution?
