Sound Breathing

Sound Breathing (の) is a Breathing Style unique only to the Sound Hashira Tengen Uzui. The Sound Breathing is branched out from the Thunder Breathing.

This combat style involves using a battle strategy called a "Score", which involves Tengen reading his opponents movements and deconstructing them into sound by analyzing the rhythm of their movements. Through this, he is able to take advantage of their openings to much greater effect by striking in a way similar to making the beat to a song. In conjunction with this, he uses small but powerful anti-demon bombs made with a special gunpowder that are capable of overpowering an Upper Rank Demon briefly, and uses his sound abilities to make sure there is no collateral damage on humans when throwing them out of his line of sight.

Since this combat style can only be used by Tengen, it can only be used with a specific set of weaponry, which is two larger-than-normal Nichirin Blades, which each have a notch in the sharp ends of their blades and are held together at the hilt by a metal chain. His swords are said to have large amounts of explosive power, and it is stated that, until Tengen's fight with Upper Rank 6, no one had ever survived a blow from them.

Attacks

 * First Form: Roar (ノ) - Uzui lifts his twin swords above his head and slams them down with great force whilst simultaneously creating an explosion with his bombs, causing a loud sound resembling thunder.
 * Fourth Form: Constant Resounding Slashes (ノ) - Uzui holds his swords apart and spins them rapidly in conjunction with releasing his bombs, making this technique a combination of offense and defense.
 * Fifth Form: String Performance (ノ) - Uzui holds one of his swords with a reverse grip and spins the other using the chain that connects them. He couples this by also releasing numerous bombs to detonate. This technique was able to overpower an Upper Rank Demon.
