Season: 6

Sasuke fights Killer Bee and is injured by his swords. Karin heals him, and Sasuke, Suigetsu, and Jugo then begin a combined assault on Bee until he decides to use the Eight-Tails' power. Sasuke is injured and revived again by Jugo, who regresses in age as a result. All healed, Sasuke unleashes Amaterasu on Bee, finally able to subdue him. Meanwhile, two Cloud ninja watch the fight from a cliff, and they notice the Uchiha crest on Sasuke. They rush the news to Bee's big brother, the Raikage.

The Konoha teams decide to head back home as Sasuke remembers that he saw Itachi crying after the massacre. He then states that he cannot rebuild the Uchiha clan in the same way that Itachi had envisioned. Madara, happy that he can use Sasuke for himself, assigns Taka the task of capturing the Eight-Tails while Akatsuki hunts the last two. Taka tracks down the host, Killer Bee, to the Land of Lightning and engages him in battle. Bee manages to overpower Jugo and Suigetsu before Sasuke steps up to fight him one-on-one.

After Madara finishes telling Sasuke about his past, he reveals the unfathomable truth about Itachi's massacre of the Uchiha Clan. What really happened on that night? Why did Itachi join Akatsuki? And for what reason did he really spare Sasuke's life?

Seeking to gain Sasuke's trust, Madara reveals to him the origins of Konoha. Madara and the future First Hokage founded the village long ago, but a rivalry between them would one day stem a chain of events leading to THAT night, the night that Itachi Uchiha annihilated the Uchiha Clan.
