Ice Breathing

**Ice Breathing** (氷の呼吸, *Kōri no Kokyū*?) is a Breathing Style derived from Water Breathing.

## Overview

Ice Breathing is a Breathing Style that mimics ice and snow, specifically their smooth yet sharp structure and replicates it with the user's movements, techniques and abilities. Most, if not all, known techniques involve the user bending their body, limbs and weapon in graceful yet soft and sharp turns and attacks that put their focus on rapid movements also making them hard to attack by opponents. The users also focuses on lowering their body temperature and releasing cold air from their body, putting them in state of intense focus. When utilized properly, users of Ice Breathing visualize themselves seemingly creating and manipulating shards of ice, snow or both simultaneously when unleashing its techniques, causing the snow and ice to seemingly emanate from their weapon, surroundings or themselves when unleashing their techniques.

Although its records were rarely saved, it is revealed by Dumisani Mavundla to the Heisei Generation Hashira that the Breathing Style was created in the Sengoku Era during the Golden Age of the Demon Slayer Corps by a woman named Yuna Hasukori who attempted to also learn Sun Breathing from Yoriichi Tsugikuni but couldn't. Yoriichi at first taught her and fellow Demon Slayers Yusuke Mizuhara and Yuri Hanae a modified style that focused on bending their body, arm, and weapon in a fluid motion to match the movements of rushing or flowing water (it became Water Breathing later). While Minami modified it further into a graceful combat style she used in conjunction with her vision (which became Flower Breathing later on), Yuna modified Water Breathing further to enable her bend her body, limbs and weapon in graceful yet soft and sharp turns and attacks that put her focus on rapid movements also making her hard to attack by opponents, like the smooth yet sharp structure of ice and snow. She further developed it in the high altitiudes of a frozen mountain. After creating the Breathing Style, she named the style after this feature and herself (the 'Kori' in her surname means 'Ice). Thus, Ice Breathing was born.

After the death of Muzan Kibutsuji, Ice Breathing, like Sun Breathing and the other Breathing Styles, became a ritual dance known as the **Korinokami Kagura** (氷の神 神楽, *Kōrinokami Kagura*?, lit. "Dance of the Ice God") offered to the Shinto deity of rain and snow, Kuraokami.

## Weaponry used with this Breathing Style

Most known users of the Ice Breathing have wielded Nichirin swords whose blade is sky blue in color.

## Techniques

Ice Breathing also has the peculiarity of being enormously versatile, so a lot of Demon Slayers using this breathing involuntarily create or in general modify the forms adapting them to their body and their abilities. The techniques are ten in total.

1. **First Form: Cold Wave (壱ノ型: 寒波, *Ichi no kata: Kanpa*) -** The user performs multiple and rapid cuts that are deep and angled perfectly for slashing the target's arms and legs in two or more cuts when uninterrupted.
2. **Second Form: Ice Break (弐ノ型: 氷壊す, *Ni no kata: Kōri Kowasu*) -** A simple yet explosive form. The user twists their body and swings their sword diagonally, with built up momentum and force.
3. **Third Form: Frost Hail (參ノ型: 霜雹, *San no kata: Shimo Hyō*) -** The user twists their wrists and slashes repeatedly in a vertical motion, like hard hail striking skin. The slashes don't have to cut super deep, they just have to cut to wear the target down.
4. **Fourth Form: Glacier Burst (肆ノ型: 氷河劈く, *Shi no kata: Hyōga Tsunzaku*) -** The user builds up a inner strength, taking a deeper breath, and once enough air is built up, the user releases it in a powerful and quick slash attack.
5. **Fifth Form: Snow Sword Dance (伍ノ型: 雪剣舞義, *Go no kata: Yuki Kenbuyoshi*) -** The user rushes forward whilst delivering several rotating sword slashes that defend themself from incoming attacks or to cut up as many targets whilst running forward.
6. **Sixth Form: Avalanche (陸ノ型: 雪崩, *Roku no kata: Nadare*) -** The user lunges into the air and releases hard hitting, yet quick slashes near the head, neck, and shoulders.
7. **Seventh Form: Ice Shard (漆ノ型: 氷の破片, *Shichi no kata: Kōri no Hahen*) -** The user unleashes an attack using the point of the blade to make a precision pierce. It can be used on demons or inanimate objects.
8. **Eighth Form: Bottom Freeze (捌ノ型: 底の氷結, *Hachi no kata: Soko no Hyōketsu*) -** The user slashes the target from the feet, up. It requires great speed and strength to cripple or harshly injure the target.
9. **Ninth Form: Absolute Blizzard (玖ノ型: 絶対吹雪, *Ku no kata: Zettai Fubuki*) -** The user releases an almost unlimited barrage of slashes and cuts, with any cut being a good cut, since the goal is to expend the targets regeneration abilities.
10. **Tenth Form: Ice Spirit (拾ノ型: 氷精神, *Jū no kata: Kōri Seishin*) -** The Final Form of the Ice Breathing, which is also the strongest & yet the hardest form of Ice Breathing & takes a lot of effort to cast; a lot of rotations to gain momentum & strong grip to the sword, with seemingly takes the form of a Japanese dragon made of ice and hail & user's attack power will significantly increase.
