Blaze Release: Kagutsuchi

As a Blaze Release technique accessible by a select few with the Mangekyō Sharingan, one uses this technique to apply Shape Transformation to the inextinguishable black flames of Amaterasu, manipulating them at will. With it, they may even create a barrier that not only shields them, but also burns and pierces any opponent that touches the flames. As this technique stems from Amaterasu, the properties of the infamous black flames may be used to a strategic advantage over a foe.

Influence
Similar to other Mangekyō Sharingan abilities, Kagutsuchi's name is derived from Japanese myth and religion. Kagutsuchi is the God of Fire in Shinto and the one who brought death into the world by burning his mother Izanami to death as she gave birth to him. This made his father, Izanagi, kill him with the Totsuka sword.
