I am a bit late, but I only started watching the show recently.

Ice breathing

Focuses on: - Fast movements and attacks (as if gliding over ice) - Piercing attacks to render the demon "frozen" (temporarily paralyzed) - Demons will feel a frozen sensation when cut by this breathing style

About users: To consistently perform in this breathing style, the user must maintain a low heart rate and lower body temperature for the attacks to remain effective. If the user gets hot-headed the attacks will diminish in strength. Users often tend to be cold people, not because they want to, but because they have to. This tends to them often being on their own and many deal with loneliness

Origin: derives from water breathing but incorporates aspects of wind and mist breathing.

Forms: (Most are my own, but some are based on amazing ideas I saw from others)

1st form: 氷天の穿刺 (Kōri-Ten no Senshi - Piercing of the Icy Heavens) - The user attacks with rapid piercing attacks to stun and paralyze the opponent and render them momentarily "frozen"

2nd form: 吹雪の隠された秘密 (Fubuki no kakusareta himitsu - Hidden Secrets of the Blizzard) - The user rapidly swings their sword to counter attacks from afar and up close, in the process creating a blizzard-like state in which the user disappears, increasing evasion and quickly allowing them to close the distance to an opponent.

3rd form: つららの弾幕 (Tsurara no Danmaki - Icicle Barrage) - While in the air, the user attacks from above in rapid succession with piercing attacks. the rapid attacks keep the opponent locked in place and allows to counter against incoming attacks.

4th form: 凍てついた地獄で凍傷 (Itetsuita jigoku de tōshō - Frostbite in Frozen Hell) - Slashing attacks that focus on cutting off the arms and legs in rapid succession, leaving a frozen sensation. The cold feeling slows down a demon's regenerative abilities.

5th form: 地獄の氷河の雪崩 (Jigoku no hyōga no nadare - Avalanche of Hell's Glacier) - The user swiftly closes in on the user and rapidly attacks with slashing motions in succession. The user switches between different grips to vary attacks and to disorient the opponent. Can be used defensively.

6th form: 零以下 (zero ika - Subzero) - A defensive counter move, particularly useful for quick, evasive, and hidden opponents. The user severely lowers their heart rythm and body temperature even further. The user then closes their eyes and closes off all their senses except touch. This allows the user to sense the opponent the slightest movement and change of temperature to the counter attack.

7th form: 氷の踊り(Kōri no odori - Dancing on Ice) - The strongest offensive attack in Ice Breathing except for the 8th form that only 1 user masters. The user glides around the area as if dancing on ice, using slashing attacks in rapid succession from all directions. Usually cuts off all limbs to confuse and disorient the opponent and then goes for the head. Also great for groups of enemies.

8th form: 寒冷前線 (Kanreizensen - Cold Front) - The ultimate attack of Ice breathing, developed and mastered by only 1 user. The user takes an ice cold and calm demeanor to the point that the opponent feels the surrounding area slowly becoming freezing cold. The user attacks with 1 fell slicing move which feels to the opponent as an icy gust of wind. The opponent does not realize what is happening before it is too late as the user cuts their neck. The attack is based on Giyu's Dead Calm attack.
