Explosion Release is an advanced chakra nature. This chakra nature seems to give the wielder the ability to utilize explosive chakra in combat, allowing them to cause explosions in objects they come into contact with. Gari of Iwagakure is the only explicit known user of this kekkei genkai. It is unknown what this nature entails.
