Flame Breathing

Flame Breathing (の) is one of the five main Breathing Styles directly derived from Sun Breathing. The Flame Breathing combat style mimics the burning effect of fire and replicates it with the users swordsmanship.

The Flame Breathing style seemed to have been developed by a distant ancestor of the Rengoku Family, who was originally a student of Yoriichi Tsugikuni. It can be assumed that this student attempted to master the Sun Breathing but, due to him not being as innately powerful as Yoriichi, his teacher altered his Breathing Style training in order to better focus on his students individual strengths and weaknesses. Eventually, his student continued to develop and train this style until it became its own unique breathing and was subsequently named the Flame Breathing. Since then, this particular Breathing Style has been passed down and taught through generations of his descendants and the future members of the Demon Slayer Corps.

Techniques

 * 1) First Form: Unknowing Fire (ノ) - Kyojuro charges towards his opponent at high speed and decapitates them in one or multiple slashes. This technique had enough force to launch train carriages off the tracks a short distance.
 * 2) Second Form: Rising Scorching Sun (ノ り) - Kyojuro releases an upward slash attack.
 * 3) Third Form: Fiery Spirits (ノ)(Movie Exclusive and Temporary Translation) - Kyojuro swings his blade downwards in an arc.
 * 4) Fourth Form: Blooming Flame Undulation (ノ のうねり) - Kyojuro spins his sword in a circular motion, defending him from all incoming attacks.
 * 5) Fifth Form: Flame Tiger (ノ) - Kyojuro unleashes a powerful sword slash that takes the form of a flaming tiger.
 * Ninth Form: Rengoku (ノ) - A devastating dashing slash that Kyojuro initiates from a high stance, the technique had enough power to carve a deep impression in the ground where he used it. Before using this technique he remarked to himself about "slashing up a broad area." In the movie, this attack takes the form of a flaming dragon with blue eyes.
