Amaterasu: Flame Wrapping Fire

Sasuke manipulates nearby flames of Amaterasu to cover the ribs of Susanoo with the flames, surrounding himself with a cloak, or "shield", of black fire. This causes enemies to hestitate to attack him, as they would be ignited by contact with the shield. Although theoretically, this technique is psychologically effective, reckless, straight-forward enemies such as A will not be affected. Also, it has no effect on the user's physical defense besides the already-exisistng bones of Susanoo.
