Blaze Release

is a technique used by Sasuke Uchiha, that allows him to manipulate the unquenchable black flames of Amaterasu, fashioning them into various weapons and defences. He can also extinguish these flames at will. After entering its final form, Susanoo gained an orb of black flames, which serves as an alternate source of flames to manipulate with this nature.

C stated that Sasuke manipulates the flames with his right Mangekyō Sharingan whereas he casts Amaterasu with his left. While this technique's name ends with the characteristic, it is unknown if Blaze Release is an advanced nature and if it is, what elements it's made up of.

Tobirama Senju recognised the technique when Sasuke used it during the Fourth Shinobi World War, implying there have been other users in the past.
