In the magical world of Zyword, the kingdom of Araimel has been attacked by the Holy Valstoke Church, which has left the area defenseless and under a deep sleep spell. The only survivors of the tragedy are 14-year-old Princess Lunatia Araimel and her longtime companion, Roddy, both of whom have magical abilities as a Decipherer and a Spell Breaker, respectively. Capable of collecting Spell Balls that make up the magic that exists in the world, Lunatia plans to acquire the Dawn Shield spell that may be able to save everyone.

While up against an enemy goddess, the pair unexpectedly finds an ally among one of the monster soldiers—a boy shrouded with mysterious power and seventy thousand spell markings all over his body. Giving him the name Ride, Lunatia and Roddy bring the amnesiac boy along in their fight against the Goddesses of Chaos all over the land of Zyword.
