Hinokami Kagura

For generations the Kamado family handed down Hinokami Kagura alongside their Hanafuda earrings, treating it as a ritual dance performed each new year. From dusk until dawn the dancer offers twelve repeating segments to the Fire God to keep sickness and misfortune away (Chapter 151). Tanjuro Kamado observed that the breathing behind the dance lets a performer move all night without tiring (Chapter 40). Tanjiro Kamado, who learned it from his father, became the last to wield it in battle.

Shinjuro Rengoku later identified the dance as Sun Breathing, the original style thought lost to history (Chapter 178). Its creator, Yoriichi Tsugikuni, reshaped it into lesser versions for students who could not match his talent, which is how all other styles came to exist. Sun Breathing copies the sun, has no fixed pattern, and proves the most versatile and effective art against demons. After studying his ancestor Sumiyoshi's memory of Yoriichi's perfect movements, Tanjiro stripped wasted motion from his own forms and wielded the style in its purest shape, to the point that Muzan Kibutsuji saw Yoriichi's face overlap his (Chapter 192).

Yoriichi originally built twelve interconnected forms. These include Dance, a single arcing downward cut; Clear Blue Sky, a full circular slash; Raging Sun, two sweeping horizontal arcs; Burning Bones, Summer Sun, a spiraling defensive strike; Setting Sun Transformation, a backflipping beheading cut; Sun Halo Dragon Head Dance, a chain of slashes shaped like a solar dragon; Fire Wheel, a circular vertical cut from behind; and Flame Dance, a two-strike combination.

Upon facing Muzan, Yoriichi devised an unnamed Thirteenth Form (Chapter 193), which cycles through all twelve in endless succession to sharpen their speed and accuracy. It was built for one purpose, destroying the twelve vital organs Muzan keeps moving inside his body. Tanjiro also created a personal variant called Dancing Flash, blending Thunder Breathing's leg-focused burst with the heavy cut of Dance.

Yoriichi Tsugikuni created the style, and the Kamado line carried it forward through Sumiyoshi, Tanjuro, and Tanjiro Kamado. After Muzan's fall the art endured as a ceremony rather than a weapon, performed once a year. Tanjiro's distant descendants Kanata and Sumihiko Kamado both practice it in the present day, unaware of its combative past.
