Breath of Flames ( (ほのお) () (きゅう) Honō no kokyū?) is one of the five main Breath Styles directly derived from the Breath of the Sun.The breath style of the Breath of Flames seemed to have been developed by the distant ancestor of the Rengoku Family, who was originally a student to Yoriichi Tsugikuni, who had attempted to teach him the Breath of the Sun, but instead alternated his teaching methods to better suit his student,thus creating the Breath of Flames, since then this particular Breath Style has been passed down and taught through generations of his descendants.
