Air Void Technique

 is one of the most dangerous techniques ever used by Shin Hyō. The technique allows him to erase the oxygen from surrounding environment causing respiring organism to choke and even go into cardiac arrest. He can absorb air from a given area to cause a massive implosion, or to cause others to suffocate. Shin can also release the air in order to create an explosion that can even break through rock. Since, he absorbs the very air itself all of fire-based techniques or sound-based- techniques become useless against him.
