A living mineral, a living stone... A living jewelry. Irisite is the rarest and most valuable jewelry in the world.

When Feilin lands his plane in some small town to fix the engine, he comes across Jura--a girl who is no mere human. Jura is one of the Iris, the living stone. Once the Iris grows up, their eyes will become a precious gem called Irisite, and merchants who sell jewelry for a living will take them out while the Iris is still alive. The blind Iris will later be sold as a slave.

Feilin feels sorry for Jura and wants to help the young girl escape from her owner, an evil merchant who is a powerful figure and wants to keep Jura for his own benefit.
