Negation Magic

Negation Magic (否定魔法 Hitei Mahō) is a type of Caster Magic utilized by Tzai.

Description
An extremely powerful Magic which allows its user to nullify or prevent different forms of Magic from being used. The effects vary with each spell.

Limitations
Despite being extremely effective at shutting down all forms of Magic, Negation Magic is not absolute.
 * Celestial Spirit Magic: Negation Magic cannot unsummon Celestial Spirits because it cannot be used to forcibly close Celestial Spirit gates, which are a different kind of supernatural phenomena. However, the magical abilities of the Celestial Spirits themselves are still affected.
 * Dragon Slayer Magic: Dragon Slayers cannot be robbed of their ability to eat their respective elements.
