Celestial Breathing (天體の呼吸,Tentai no kokyū?) is a Breathing Style personally developed by Shizuka Rengoku that is derived from the Starry Night Breathing that was passed on from her family from generation to generation. Celestial Breathing allows Shizuka to take advantage of her own speed, strength, and reflexes.
First Form: Star Fall (壹ノ型流れ星,Ichi no kata: Nagareboshi?) - Similar to the Water Breathing, Fifth Form: Blessed Rain After the Drought, this form allows the swordsman to kill their opponent with little to no pain, causing them to die peacefully.
Second Form: Night of Haven (貳ノ型夜の避難,Ni no kata: Yoru no Hinan?) - Increases the power and agility in their attacks, though it is rarely used by Shizuka herself.
Third Form: Before the Lights Fade (參ノ型前の燈褪,San no kata: Mae no Akariaseru?) - The swordsman uses their strength while using this form - she is able to manipulate her own strength and the pain that will be inflicted on the target.
Fourth Form: Zero Eclipse (肆ノ型零蝕,Shi no kata: Zero Nisshoku?) - By using this form, the wielder is able to enhance their own stamina by a little amount and the agility of their attacks, similar to the Second Form, though the difference is that this form grants the user more stamina and balance their breathing evenly.
Fifth Form: Dark Matter (伍ノ型暗黑物質,Go no kata: Ankoku Busshitsu?) - The swordsman kicks onto a surface, leaping themselves into the air. While airborne, they spin along with their sword, aiming for the eyes of their opponent, blinding them temporarily before mercilessly beheading their enemy.
Sixth Form: Nebula (陸ノ型星雲,Roku no kata: Seiun?) - The swordsman swings their sword, creating a chaotic vortex of slashes into the direction they desire, their blade inflicted with poison that will cause their target's mind to be clouded with illusions that they would unintentionally create in their heads.
Seventh Form: Star Cluster (漆ノ型星團,Shichi no kata: Seidan?) - The swordsman takes advantage of gravity and swings their sword forward, creating groups of powerful slashes.
Eighth Form: Heavenly Blessing (捌ノ型天の祝福,Hachi no kata: Ten no Shukufuku?) - The swordsman gets blessed by the gods above, getting a hardened body which increases speed, agility and the techniques are more destructive, powerful and when moving, leaves a trail of star dust behind. Can be used for retreating defensive and offensive capabilities. Last for 20 seconds.
Ninth Form: Galactic Celestial Dragon (玖ノ型銀河天竜人,Ku no Kata: Ginga Tenryū Hito?) - This form is similar to Water Breathing:Tenth Form: Constant Flux, but the difference is that this form is deadlier and when it reaches contact with an enemy, hundreds of star-shaped slashes fly everywhere killing enemies nearby. This form is good when you are surrounded by enemies or for destroying the enemy.
Tenth Form: Cosmic Radiation (拾ノ型宇宙放射線,Jū no Kata: Uchū Hōshasen?) - The gravity around the swordsman is greatly increased making the enemy paralized from where it stands. Then when it slashes an enemy, hundreds of wisteria-like radiation (or poison) gets into the enemy instantly incinerating them. When the enemy somehow dodges this slash, the radiation around the swordsman will still kill them but slower. This form is useful when the enemy keeps dodging your attacks or you just want to end the battle quicker.
