Beast Breathing

**Beast Breathing** (獣 (ケダモノ) の呼 (こ) 吸 (きゅう) , *Kedamono no kokyū*?) is a Breathing Style that is distantly derived from Wind Breathing.

## Overview

Beast Breathing is a Breathing Style that mimics beasts/wild animals, specifically their unpredictable, ferocious 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, straight-forward 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 of Beast Breathing also visualize themselves seemingly manifesting the fangs and claw slashes of a wild animal 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 can be assumed that it can only be utilized by someone with dual Nichirin katanas and an extremely acute sense of touch.

## Known Techniques

Beast Breathing has ten known techniques with an improvisation technique created during Inosuke's fight with Doma. Unlike other Breathing techniques, only supplement moves are called "Forms", as assaulting Beast Breathing moves are called "Fangs" instead.

* **First Fang: Pierce** (壱 (いち) ノ牙 (きば) 　穿 (うが) ち抜 (ぬ) き, *Ichi no kiba: Ugachi Nuki*?) - The user stabs the target's neck with both blades.

* **Second Fang: Slice** (弐 (に) ノ牙 (きば) 　切 (き) り裂 (さ) き, *Ni no kiba: Kirisaki*?) - The user unleashes a double slash with two blades in an X-shaped cut.

* **Third Fang: Devour** (参 (さん) ノ牙 (きば) 　喰 (く) い裂 (ざ) き, *San no kiba: Kuizaki*?) - The user releases two simultaneous horizontal slashes towards the target's throat to decapitate them.

* **Fourth Fang: Slice 'n' Dice** (肆 (し) ノ牙 (きば) 　切 (きり) 細 (こま) 裂 (ざ) き, *Shi no kiba: Kiri Komazaki*?) - The user delivers multiple diagonal double slashes with both swords.

* **Fifth Fang: Crazy Cutting** (伍 (ご) ノ牙 (きば) 　狂 (くる) い裂 (ざ) き, *Go no kiba: Kuruizaki*?) - The user slices everything in all directions while in mid-air.

* **Seventh Form: Spatial Awareness** (漆 (しち) ノ型 (かた) 　空 (くう) 間 (かん) 識 (しき) 覚 (かく) , *Shichi no kata: Kūkan Shikikaku*?) - The user utilizes their sense of touch to identify the position of enemies and their weaknesses by feeling small disturbances in the air. This technique was so strong that Inosuke Hashibira could sense all the demons spread out through a whole mountain.

* **Eighth Form: Explosive Rush** (捌 (はち) ノ型 (かた) 　爆 (ばく) 裂 (れつ) 猛 (もう) 進 (しん) , *Hachi no kata: Bakuretsu Mōshin*?) - The user charges towards their opponent at blinding speeds, ignoring all incoming attacks.

* **Ninth Fang: Extending Bendy Slash** (玖 (く) ノ牙 (きば) 　伸 (しん) ・うねり裂 (ざ) き, *Ku no kiba: Shin - Unerizaki*?) - The user dislocates the joints of their arm to increase the range of their attack, and then unleashing a fast swinging forward strike.

* **Tenth Fang: Whirling Fangs** (拾 (じゅう) ノ牙 (きば) 　円 (えん) 転 (てん) 旋 (せん) 牙 (が) , *Jū no kiba: Enten Senga*?) - The user rapidly spins their swords in a circular motion, deflecting enemy attacks such as projectiles.

### Game Exclusive Techniques

* **Third Fang: Devour Rush** (参 (さん) ノ牙 (きば) 　猛 (もう) 進 (しん) ・喰 (く) い裂 (ざ) き, *San no kiba: Mōshin - Kuizaki*?) - The user rushes towards their opponent and stabs them with both blades, dragging them along the ground with their momentum. They then turn and throw them high up into the air, readying the **Third Fang: Devour** as they slice them in an X-like pattern above them at the falling opponent.
* **Sixth Fang: Palisade Bite, Feral Rush** (陸 (ろく) ノ牙 (きば) 　乱 (らん) 杭 (ぐい) 咬 (が) み・爆 (ばく) 進 (しん) , *Roku no kiba: Ranguigami - Bakushin*?) - The user performs a charging headbutt at the opponent to knock them away then uses **Eighth Form: Explosive Rush** to close the distance between them, followed up with **Sixth Fang: Palisade Bite** and a few more slashes to top it off.

## Demonstrations

* Anime
* Manga

## Trivia

* In the manga, whenever a Beast Breathing user performs their techniques, they visualize themselves creating slashes that are bright gray in color with a black outline. However in the anime, the slashes are bright white fading to light blue in color with the same black outlines instead.
* In the manga, **Second Fang: Slice** creates an actual X-shaped cut whereas in the video game and anime, they don't and instead creates two overhead slashes as Inosuke seems to perform the technique in a similar fashion as Sound Breathing's **First Form: Roar**.
