Synopsis
With the invasion's start, Orochimaru takes the Third Hokage hostage as the Sound Four creates a barrier to allow them to fight without interruption. One of the ANBU chasing after them touches the barrier and dies. Meanwhile, invading Sound and Sand ninja infiltrate Konoha, and battles begin breaking out across the village. Kankurō and Temari carry Gaara from the village so that he can recover. Sasuke pursues them, eager to finish their battle. Preoccupied with fending off the invading forces, Kakashi instructs Sakura, who had managed to repel the sleeping-inducing genjutsu, to wake Naruto and Shikamaru. He tells her that they are getting a mission after a long time. Meanwhile Might Guy, Aoba and another Jonin battle the Sound ninjas. Sakura ducks and proceeds to release the Genjutsu on Naruto and Shikamaru.
