Moon Breathing

Breath of the Moon (の) is a Breath Style of unknown origins outside the fact that its only known user is Upper Moon One demon, Kokushibo, who was also one of the first Demon Slayers. The breath allows the user to create many "chaotic blades" when slashing that vary in length and size. It is not known at one point the Breath Style was developed. This particular Breath Style has no known human user,as its possible creator or last living inheritor to this breath style is the immortal Demon Kokushibo,who due to his status as a demon instead opted to continue to develop and add techniques to the breath styles over the centuries of his immortal life instead of entrusting the Breath Style to a heir. At this point in the story it is the only Breath Style to possess at least 16 different techniques, easily surpassing the other Breath Styles who at best have up to 11 techniques. This however does include the Dance of the Fire God, which at the moment has 12 techniques and theoretically could have has many as Tanjiro can learn given it is the origin of all the Breath Styles.
