Blaze Release: Kagutsuchi

This technique shapes the inextinguishable black flames of Amaterasu into a spiked barrier that not only shields the user, but also burns and pierces the opponent if they touch them. This technique seems to be controlled by Sasuke's right eye, unlike his Amaterasu, as he was covering his left when using it.

Influence
Similar to other Mangekyō Sharingan abilities Kagutsuchi's name comes 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.
