Flame Breathing

Flame Breathing (の) is one of the five main Breathing Styles directly derived from Sun Breathing.

Description
Flame Breathing is a Breathing Style that mimics flames and replicates it with the user's movements, techniques and abilities. Most, if not all, known techniques and forms involve extremely powerful singular strikes and movements that are so intense, it 'burns' the opponents. Users that have mastered Flame Breathing visualize themselves seemingly creating and manipulating fire when unleashing its techniques.

The Flame Breathing was 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.

Known Techniques
Flame Breathing has 9 known techniques, with the esoteric art, Ninth Form: Rengoku being exclusive to the Rengoku family.
