Sound Breathing ( (おと) () (きゅう) Oto no kokyū?) is a Breathing Style derived from Thunder Breathing.

Description

Sound Breathing is a Breathing Style that mimics sound, specifically its disorientating loudness, and replicates it with the user's movements, techniques and abilities. Most, if not all, known techniques and forms utilize an object that creates huge amounts of sounds and uses that as a powerful attacks and effective confusion to close in, as well as extremely fast movements similar to how fast sound travels as well as make use of the user's sense of hearing. Users that have mastered Sound Breathing visualize themselves seemingly creating and manipulating sound when unleashing its techniques.

The only known user, Tengen Uzui uses a battle strategy called a "Score", which involves Tengen using his incredible hearing 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. His combat style focuses on generating huge amounts of sound to overwhelm his opponents. 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 Katanas, 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 Six, no one had ever survived a blow from them.
