Alright it's often contested on the base whether or not Shisui had KA in both eyes or if he had a different genjustu in the eye that he gave to Danzo. I want to establish that Shisui did in fact have KA in both of his eyes and that Danzo did in fact use KA on Mifune
First, I want to note that Danzo did have MS. It's shown here that Shisui had MS in both eyes before he died:
Second, both Itachi and Ao referred to the genjustu Danzo used the and the genjutsu the crow used as "one of the most powerful eye techniques" and "the ultimate genjustu":
Ao-
Itachi-
Also note that they're both referring to a singular technique of Shisui's. So they were referring to KA
Third, both of these techniques basically control their opponents at the users whim. In Danzo's case Ao noted that Mifune couldn't even notice it. In Itachi's case, it was noted that KA overrode the ultimate control of Edo Tensei (I'm pretty sure that this one is common knowledge)
Fourth, both techniques required Hashirama's DNA to avoid the 10 year time limit on using these tech. So Danzo had Hashirama's DNA in his arm to counter the time limit:
And Itachi directly stated that KA could be used repeatedly if the user had Hashirama's DNA:
So with all that being said, I think it's pretty obvious that Shisui had KA in both of his eyes, and that Danzo had KA. But of course people have very common counter arguments that I want to address:
-Ao would have said that Danzo had KA. My problem with this is that Ao would not have known what genjustu Shisui was using on him when they first fought. He would have just seen the effects and learned about how powerful it was from seeing it with his byakugan
-Danzo kept sending multiple commands to Mifune while Itachi only received the one command "protect Konoha". My problem with this argument is that Danzo was trying to be discreet about controlling Mifune because of the delicate situation he was in; all the crow had to do was order "protect Konoha" and Itachi/Sasuke would have joined Naruto's side immediately. If Danzo had simply ordered Mifune to "choose Danzo as the leader of the alliance," Mifune then would have stopped being controlled and may have not been able to justify his previous action. Danzo didn't know that Mifune was going to select him, so to be sure he chose himself and gave a good excuse as why the other Kage's shouldn't be the leaders of the alliance. That's why he had to send multiple commands instead of just saying "choose Danzo"
-MS users need to have a unique technique in each eye so that they can unlock Susanno. This is pure speculation, we don't know if you're supposed to have two different MS tech's in each eye. I know that Sasuke and Itachi do, but we hardly know anything else about the four other Mangekyo Sharingan users and what techs they have, had, or might have had if they were alive
So Shisui had KA in both of his eyes, and Danzo had KA. I honestly think that Kishi messed up and realized that he wanted Danzo and Itachi to have KA after Shisui's death so he gave Shisui the same tech in both eyes. But the point is that Danzo did have KA, it wasn't just unique to Shisui's left eye
Do you guys agree?
