"Sasuke's Victory" (サスケの勝利, Sasuke no shōri) is chapter 394 of the original Naruto manga.
Summary
Itachi's Amaterasu continues to burn the area. After a few speechless moments of watching, Zetsu realizes Itachi has died despite almost succeeding in taking Sasuke's eyes. He notes that the fight was unusual, as Itachi's movements were sluggish and he otherwise seemed weak. Sasuke is unconcerned, smiling for finally killing his brother before he collapses from exhaustion. Elsewhere, the Konoha ninja pursuing Sasuke rule out all possible explanations for why Tobi is not being damaged by their attacks. Opting to capture instead of damage him, Shino prepares his kikaichū for battle.
