Sasuke's Susanoo…!! (サスケの"須佐能乎"…!!, Sasuke no "Susanoo"…!!) is chapter 478 of the Naruto manga.
Danzō recognises Itachi as a product of Sasuke's Tsukuyomi, though Sasuke's is vastly inferior to Itachi's. He restrains Sasuke and tells him as much, which makes Sasuke angry enough to finally complete his Susanoo. Susanoo fires an arrow at Danzō, who is forced to use the Wood Release abilities that he gained from the implanted DNA of Hashirama to avoid the attack. Since this means he would have died, Sasuke assumes Danzō is now vulnerable and attacks again, only for him to once again survive the attack after seeming to die. Tobi conduces that Danzō is using Izanagi.
In the original Shōnen Jump release this chapter was called The Complete Form of Susanoo…!! ("須佐能乎"完全体…!!, "Susanoo" Kanzentai…!!).
