New Breathing Style (Ice Breathing)

Sun Breathing

Sun Breathing - is a style of swordsmanship utilized by the first Demon Slayer to use "breaths", Yoriichi Tsugikuni, and serves as the basis for other Breathing Styles derived from it as a result of Yoriichi changing the breathing techniques to suit the individuals he taught. The derived styles eventually branched out into the main breaths: Water Breathing, Flame Breathing, Wind Breathing, Thunder Breathing, Stone Breathing, and Moon Breathing. Before Kokushibo died, he mentions that all swordsman who knew of the Sun Breathing were killed by him and Muzan Kibutsuji, before proceeding to question why the Sun Breathing still persists due to the existence of the Hinokami Kagura.

Kokushibo and Shinjuro Rengoku independently identified the Hinokami Kagura as the Sun Breathing, the latter through the memoirs of his Demon-slaying ancestor. The two styles were later confirmed to be the same. There is a (previously unknown) thirteenth form, which can be learned from the Sun Breathing as a Hinokami Kagura User, that is achieved by completing the twelve movements in succession.

However, Tanjiro remained uncertain of the breathing style's true nature until he gained access to the memories of his ancestor, Sumiyoshi. His ancestor's wife, Suyako, requested to see the Sun Breathing performed during Yoriichi's last visit to the family. Sumiyoshi memorized the movements and was gifted the hanafuda earrings by Yoriichi before parting. The breathing style and earrings were then secretly passed on from father to son in the Kamado family every generation as a rite of passage. Henceforth, the Sun Breathing became known as the Hinokami Kagura.

Attacks:

Dance - A single high-powered vertical slash.

Flash Dance - First used by Tanjiro Kamado. The user utilizes a similar method like the Thunderclap and Flash technique of the Thunder Breathing, allowing them to use an advanced version of Dance by inhaling huge amounts of oxygen, increasing the pumping of blood through the entire body, focusing it on the legs, and releasing it all to assault the target with a slash. This technique was capable of outspeeding Genya Shinazugawa and Nezuko Kamado, as well as the fleeing Hantengu, although it is still said to be slower than Zenitsu Agatsuma's Thunderclap and Flash.
Clear Blue Sky - The user spins their body vertically to create a 360-degree slash. It is likely the model to the Water Breathing: Second Form - "Water Wheel."

Raging Sun - The user unleashes two horizontal slashes to hit or intercept an enemy from the front or side.

Fake Rainbow - The user utilizes this technique to evade incoming attacks with high-speed twists and rotations, thus creating afterimages. The afterimages work most effectively on enemies with good vision as they will probably fail attack the afterimage instead of the actual body of the user.

Fire Wheel - The user leaps behind the opponent and spins in the air while releasing a flaming attack in a circular motion.

Burning Bones, Summer Sun - A circular slash that defends from imminent frontal attacks.

Sunflower Thrust - A single thrust attack with the point of the blade.

Solar Heat Haze - The user charges towards the target, attacking it with a haze covered slash that seemingly fails to land, but actually does hit the target.

Setting Sun Transformation - The user flips into the air to deliver an upended flaming sword slash.

Beneficent Radiance - The user spirals into the air to deliver a powerful slash to those caught in it.

Dragon Sun Halo Head Dance - Resembling a dragon, the user moves in circles to avoid enemy attacks and slashes then multiple times at the target. This technique was first utilized by Tanjiro in conjunction with Nezuko's Blood Demon Art Blood Burst to enhance the effectiveness. Info icon.png

Flame Dance - A two-combo strike which starts with a vertical slash and then a horizontal one right after. Info icon.png

Thirteenth Form - The user continuously performs all twelve forms of the breathing style in repetitive succession to increase the accuracy and agility of his movements. This form was created solely for the purpose of killing Muzan, since the repetition of all twelve forms aims to destroy Muzan's twelve vital organs (seven hearts and five brains) that move freely inside his body thanks to his shape-shifting ability.
