Meh, That's the
moon haxx. The actuall
eye on the jubi had 4 lines. In this
picture of the sage he has 2 lines in one eye and 3 in the other. It might be that the ultimate sharingan is when you have 9 tomos. Since you can awaken MS alone, that's 3 tomos. Then you take another MS to get EMS which makes it look like Madara has 6 tomos in the lower left corner of this
page. You might not be able to do that again but have to mix it with another EMS and that's what he's wating for with Sasuke so he can steal his eyes and get 9 tomos. Sent him into battle with the kages to show him how weak he is so he'd finally accept that he needs EMS.
