In an ancient continent, a land of God known as “Alfheim” exists.

A long time has passed since the dragons who were once powerful in this world perished. Its souls were crystallized and scattered about the world.

However, a dragon survived. And its name is “Kouryuu Ilburn.” Seeking the power of the lost dragon, the Imperial Army and Church powers, and now a “Dragon Slayer” who intends to harm the dragon, have begun to stir.

The one who saved the dragon from their clutches was a single “young girl.” And before long, warriors known as “Dragon Instrumentalists” began to gather under the dragon. The dragon recalled a childhood memory of a “young girl” who saved him when he was injured. It was a reunion of fate.
