Shadar

Shadar, also known as the Dark Djinn as well as the Executor, is the secondary antagonist of Ni No Kuni Wrath of the White Witch. He is an evil wizard who has the power to interfere with a person's heart. This may leave them in a husk-like state or corrupt their hearts with negative emotions. This can have deadly consequences. His powers have made him feared throughout the world and it is Oliver's duty to repair the hearts that have been damaged by Shadar.
