(Hinokami Kagura is a special dance taught by members of the Kamado family in Demon Slayer. Tanjuro Kamado, Tanjiro's father, used to perform the Hinokami Kagura at the start of each year to ensure good fortune. Tanjiro starts using Hinokami Kagura instead of Water Breathing because his body is not well-suited to it, which was causing his blade to take more damage than it should've, because Tanjiro's Nichirin sword wasn't meant to be used for Water Breathing. It is later revealed that Hinokami Kagura is actually Sun Breathing, and the movements of the dance are actually the different techniques. Over time, as the Kamado family stopped being Demon Slayers, Hinokami Kagura became a dance to the Shinto kami of fire, and was used by the Kamado family as a good luck charm to bring good fortune and ward off evil. Clear Blue Sky is the name of one of the techniques)
