I have recently seen a lot of people complaining about the Itachi SA being difficult, but if you have these ninja's with 60k+ bp you can auto it easily. Ninja's you need Roshi, Sailor Sakura, and Gakido (preferably 4 star). The max score it gave me was 3182. It will vary depending on power and how quickly the AI kills Danzo. Post below if you have any questions or issues with the team.
