Breath of the Beast ( (ケダモノ) () (きゅう) Kedamono no kokyū?) is a Breath Style personally created and self-taught by Inosuke Hashibira after living in the mountains and fighting for survival. It is said to be distantly derived from the Breath of Wind. The style enhances a user's sense of touch, while being able to utilize several different techniques.
