The manipulated flames of Amaterasu are used to cover the ribs of Susanoo with the flames, surrounding the user with a shield of black fire. In addition to the damage it can inflict, this technique has the psychological effect of causing melee enemies to hesitate in attacking the user of this technique.
- While in the manga, this technique is only described as "Shield of Black Flames" (黒炎の盾,Kokuen no Tate). It is explicitly named in Naruto Shippūden: Ultimate Ninja Storm 3.
- Written as "炎天下", entenka means "under the blazing sun".
