A pair of siblings live in the Ornstein family, a lower noble family in a remote rural territory of the Kingdom of Lystia. The elder sister Mary is a lively girl who likes to practice swordsmanship with her father. The younger brother Theon is a shy boy who likes to stay in his room and read books. Although the two have completely opposite personalities, they live in harmony under the protection of their gentle parents. One day, Theon asked his father if "magic" exists in this world. However, even his father, who is a noble and well-educated, does not know the word "magic" itself. What's more, the phenomenon that Theon said "various things from elements such as fire, water, wind, and light" cannot exist in this world... From that day on, Theon seemed very lost. However, one day, in the lake where he went with his sister Mary, he witnessed an incredible phenomenon that was "like magic" - "It's too early to give up now. If there is no magic, just do it yourself!" Theon began to study magic, and steadily moved forward while involving the people around him. Flying flames, running lightning - everything is to use the "magic" that he longed for in his previous life!
