The Rhea dynasty, which ruled for many centuries, fell overnight. Only Prince Kirin, the youngest son, who was not taught to fight or rule, remained free. He, a living decoration of the palace, now holds the fate of the entire country in his hands - alone against an army of dark magicians and monsters. Good will not win this time. To save the empire, Kirin needs to find an even greater evil, the best of monsters... He could not even imagine that darkness has the form of a woman.
