Breath of the Moon ( (つき) () (きゅう) Tsuki no kokyū?) 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. However, it is known that Kokushibo continued to develop and add techniques to the breath styles over the centuries as an immortal demon. 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.
