Doll Magic is a caster type magic that allows the user to manipulate objects around them.
This Magic allows the user to take control of any object, including Celestial Spirits, except for humans. The user can even cancel out the Celestial Spirit Mage's recall of the spirit since both the spirit and the user need to be in agreement for it to happen. However, a spirit's gate can still be force closed. When the user takes control of Celestial Spirits, it seems that the user can only take control of their bodies, not their minds.
