Cosmic breathing

(Non-Canon) **Cosmic Breathing** ( 宇宙の呼吸)(Uchū no Kokyū) is a breathing style derived from Sun Breathing and Star Breathing.

Cosmic Breathing mimics the phenomenons that happen in space, such as a supernova and comets. This form also utilizes radiation and plasma energy like what stars emit. This form focuses on strength, swift and invisible movements to make reaction time less. As a result, the swordsman can fight opponents better.

## Breathing style forms

1. **1st Light Year: Big Bang** (一光年 ビッグバン Ichi no Kōnen: Bigguban) - The swordsman uses rotating sword motions to create a defensive powerful shock wave, executing a powerful attack from behind on the second part unnoticeable.
2. ***Second Light Year: Nebulae thrust*** (二光年 星雲 推力 Ni no Kōnen: Seiun Tsuki) - The swordsman blitzes their opponent diagonally with their sword laced with poison. The poison can cause their opponent to hallucinate and collapse.
3. ***Third Light Year: Comet*** (三光年 彗星 San no Kōnen: Suisei)- The swordsman multislashes and thrusts their opponent followed by a slash that can’t be seen. This movement executes itself very precisely to prevent missing their targets.
4. ***Fourth Light Year: Cosmic ray*** (四光年 六合光線 Shi no Kōnen: Rikugō Kōsen) - The swordsman slashes their sword vertically directly at their opponent’s head while light is being reflected off their sword, burning them, as the light blinds them temporarily.
5. ***Fifth Light Year: Spiral Sunstorm Chaos*** (五光年 渦状 太陽の嵐 混乱 Go no Kōnen: Taiyo Arashi Konran) - Solar Plasma surrounds the swordsman’s sword and they makes spiral movements with their sword, and spirally slashes their opponent through multiple times. They use this to burn their opponent and attack their weakness, making regeneration slower.
6. ***Sixth Light Year: Stellar Windstorm*** (六光年 星の暴風 Roku no Kōnen: Hoshi no Bōfū) - The swordsman can attack far-range using this style. They multi-blitzes their opponent with wind followed by a go through thrust, freezing their nerves so they can’t move and react.
7. ***Seventh Light Year: Constellation*** (漆光年 星座 Shichi no Kōnen: Seiza) - The swordsman does custom slashes and blitzes that create a burning light projectile towards their enemy from their sword. As it approaches them, a mirror of it appears behind its target, attacking their enemies behind if the first attack misses.
8. ***Eighth Light Year: Sunrise*** (八光年 日の出 Hachi no Kōnen: Hinode) - The swordsman laterally slashes their opponent 100 times at the speed of light. Sunset (八光年 夕焼け Hachi no Kōnen: Yūyake) - The swordsman vertically slashes the opponent 100 times at the speed of light. They also decreases their sword to absolute zero temperature to kill nerve cells, hindering regeneration.
9. ***Ninth Light Year: Supernova*** (九光年 超新星 Kyū no Kōnen: Chōshinsei) - The swordsman uses high energy by rotating their sword to create a fiery explosion when they slashes their opponent spirally precisely.
10. ***Tenth Light year: Gamma ray burst*** (十光年 ガンマ線 バースト Jū no Kōnen: Ganmasen Bāsuto) - The swordsman’s sword is surrounded with a toxic gamma radiation. They jump high and do a front flip, vertically blitzing their opponent, causing drowsiness and hemorrhage.
11. ***Eleventh Light Year: Black hole*** (十一光年 ブラックホール Jū ichi no Kōnen: Burakkuhōru) - The swordsman surrounds their sword with dark plasma energy. They come in low and multislashes their opponent rotationally, followed by a vertical and diagonal slash. The plasma helps the swordsman precisely attack their target, as their movement becomes faster, giving the opponent less time to react.
12. ***Final Light Year: Messier 31, Andromeda Galaxy*** (最後の光年 アンドロメダ銀河 Andoromeda Ginga) - Can only be used when The swordsman activates their demon slayer mark, and their blood flow to their arms and legs. The swordsman spirally rotates their sword at light speed, then fatally slashes their opponent invisibly 1 million times. They can only use it for 2 minutes as their blood pressure increases and the blood leaves their head, which causes dizziness.
