Groove Breathing

**Groove Breathing** (溝 (みぞ) の呼 (こ) 吸 (きゅう) , *Mizo no kokyū*?) is a Breathing Style derived from the Lava Breathing which itself is derived from the Flame Breathing. This breathing style is an exceptionally hard style to master due to it having the user learn how to visualize the battlefield in a rhythmic manner, similar to Tengen Uzui. It includes very rhythmic and unexpected movements that resemble that of one of Muzan Kibutsuji's lives, having the user feel the vibrations and make their forms contrast to it to lessen the chances of evasion or counterattacks.

## Attacks

1. **Total Concentration Breathing Form: Groove** (Zen shūchū no kokyū: Mizo) - The base form of Groove breathing. This form includes moving the body and breathing to the vibrations of the battlefield. It is said that if you cannot master this, you cannot learn groove breathing at all.
2. **First Form: Thriller** (Ichi no kata: Surirā) - The swordsman performs two hooking slashes on both sides as a defensively offensive technique.
3. **Second Form: Smooth Criminal** (Ni no kata: Heikatsu no hanzai) - The swordsman dashes towards the enemy and performs a slightly ranged vertical slash.
4. **Third Form: Dangerous** (San no kata: Kiken) - The swordsman performs a combination of slashes on the opponent while moving around the enemy to avoid counterattacks
5. **Fourth Form: Blood on the Dance Floor** (Shi no kata: Dansu furoa no chi) - The swordsman performs three circular slashes laterally towards the opponent, then backflips and blitzes the opponent.
6. **Fifth Form: Billie Jean** (Go no kata: Billie Jean) - The swordsman releases a barrage of slashes while moving around the enemy as a defensive technique, then does a reverse combination of slashes with the slashes being upwards while the swordsman is moving backwards.
7. **Sixth Form: Man in the Mirror, Ghosts** (Roku no kata: Otoko, yūrei) - The swordsman moves side to side in extreme speed to the point where it creates and illusion of one's self. The swordsman then performs a rotating slash which somehow does double the power. This form resembles that of Sun Breathing, Parhelion Rainbow. Contrast to the former, this illusion works best against enemies with bad eyesight.
8. **Seventh Form: Beat it** (Shichi no kata: Usero) - The swordsman shallow cuts and ruptures the skin and nerve points on the opponent. While this form will not cause much actual damage, it will make the opponent feel excruciating amounts of pain and numbness.
9. **Eighth Form: Speed Demon** (Hachi no kata: Supīdo kyō) - The swordsman blitzes the opponent with two back-to-back slashes in speed so much that it outspends that of Thunder Breathing: First Form - Thunderclap and Flash, though it causes much strain on the swordsman and does less damage per slash.
10. **Final Form: Slave to the Rhythm** (Saigo no kata: Rizumu no torikò) - The final form of Groove Breathing. The swordsman swings his sword around in such manner that it creates rhythmic vibrations that have the power to take control of one's opponents. The swordsman must maintain the rhythm through one's breathing, especially if enslaving more than one opponent. This form may cause breathing limitations which allows the limit for control to be 3-5 minutes. After this form, the swordsman may feel headaches, nausea, and loss of breath which may lead to a "coma" at worst.
