No parents. That is your power. In a magical land, an orphan rises to power using his magic as a weapon!

Ornia, a boy living in an orphanage, spends his days in depression as he is repeatedly sent back to the orphanage after being adopted. When a strange fairy suggests that he has magical powers, Ornia meets Sversen, a heretical sorcerer who is the master of the fairies. Sversen, who deeply laments the weakening of the royal family and the rise of court magicians, plans to overthrow the current royal family and the court magicians by focusing on Ornia's bloodline.
