Beast Breathing

Beast Breathing is a Breathing Style derived from Wind Breathing.

The Beast Breathing combat mimics beasts and wild animals, specifically their unpredictable and wild nature, including movements, attacks and senses, and replicates it with the user's movements, techniques and abilities. Most, if not all, known techniques and forms are simple, straightforward yet wild, unpredictable and animalistic movements and attacks. Although, one of them utilizes the powerful sense of touch to replicate an animal's primal senses. Users that have mastered Beast Breathing visualize themselves seemingly creating the claw slashes of a beast when unleashing its techniques.

Since this Breathing Style is personally created and self-taught by Inosuke Hashibira after living in the mountains and fighting for survival. It's assumed that it can only be utilized by someone with dual Nichirin Katanas and an incredible sense of touch.
