The Ansarivan Dragon Knight Academy is for boys and girls who have made a contract with dragons, teaching students how to raise them. Ash Blake has a particular Seikokuon on his hand, which serves as proof of being a contractor, but he did not have any dragon as his partner. After an incident, the boy's dragon finally hatches. However, the dragon that appeared was different from other dragons. It was not in the form of a dragon but had the form of a girl.
