Moon Breathing

Moon Breathing (の) is a Breathing Style derived from the Sun Breathing used by Upper Rank 1, Kokushibo, who was one of the first Demon Slayers who utilized breathing techniques. This combat style is one of the most powerful and deadly ones showcased thus far.

The Moon Breathing combat style allows him to create many chaotic crescent moon blades when slashing that vary in length and size in crescent shaped sword attacks using his demonic abilities. It is known that Kokushibo continued to develop and add techniques to the Breathing Style over the centuries as an immortal Demon. At this point in the story, it is the only known Breathing Style to possess at least 16 different techniques, easily surpassing the other Breathing Styles.

It has been revealed that, like all of the other original Breathing Styles, the Moon Breathing also branched out of the Sun Breathing. When its creator, Michikatsu Tsugikuni, attempted to learn the Sun Breathing from his twin brother, Yoriichi Tsugikuni, he discovered he was unable to master it and so was instead trained in an alternate Breathing Style. Yoriichi created it fit and cover his individual strengths and weaknesses, and Michikatsu then continued to train and develop this breathing until it eventually evolved into its own unique Breathing Style, which he named Moon Breathing.

Techniques

 * 1) First Form: Dark Moon - Evening Palace (ノ ・の) - Kokushibo draws his sword and slashes swiftly in a single motion; like with all Moon Breathing techniques, numerous chaotic crescent blades originate from the slash. This technique is reminiscent of Iaijutsu.
 * 2) Second Form: Pearl Flowers Moongazing (の ノ) - Kokushibo performs several slashes that defend him from incoming attacks while also creating a barrage of crescent blades.
 * 3) Third Form: Loathsome Moon - Chains (ノ ・り) - Kokushibo swings his sword rapidly in two gigantic crescent slashes, from which a storm of smaller crescents spread. This technique causes huge destruction in a small area.


 * Fifth Form: Moon Spirit Calamitous Eddy (ノ) - Kokushibo makes multiple curved slashes layered over one another, resembling a rising vortex. Sanemi noted that Kokushibo performed this attack without swinging his blade.


 * Sixth Form: Perpetual Night, Lonely Moon - Incessant (ノ ・) - Kokushibo releases a wild barrage of crescent-shaped slashes in front of him. This technique was powerful enough to not only slice up multiple Hashira around him but also overwhelm the Wind Hashira Sanemi Shinazugawa.


 * Seventh Form: Mirror of Misfortune - Moonlit (ノ ・え) - Kokushibo swings his sword in a powerful frontal slash that then creates a multi directional frontal assault, powerful enough to create several deep gouges in the ground and push back two Hashira.


 * Eighth Form: Moon-Dragon Ringtail (ノ) - Kokushibo triples the range of his normal attack radius and creates a singular gigantic slash that slowly decreases in size.


 * Ninth Form: Waning Moonswaths (ノ り・) - Kokushibo creates a seemingly endless stream of claw-like vertical and horizontal slashes, capable of cutting down his intended target from a long range.


 * Tenth Form: Drilling Slashes - Moon Through Bamboo Leaves (ノ ・) - Kokushibo creates a triple-layered slash twister, capable of mowing down his targets into three clean pieces.


 * Fourteenth Form: Catastrophe - Tenman Crescent Moon (ノ ・) - One of Moon Breathing's most powerful techniques. An advanced and more powerful version of Kokushibo's Fifth Form. He swings his sword and creates a chaotic vortex of powerful omni-directional slashes that destroys whatever is caught up within its attack radius.


 * Sixteenth Form: Moonbow - Half Moon (ノ ・れ) - Possibly Moon Breathing's most powerful technique. Kokushibo creates a barrage of downward crescent slashes, resulting in a powerful sixfold slash crashing down on his opponents; the attack itself is powerful enough to create several miniature craters where the slashes have landed. As this technique is so wide-ranged, it is able to easily surround and overwhelm multiple enemies at once.
