Are you even reading what you’re writing? Did someone hack your account? It would be a shame to even call it far-fetched, it is something only a fanatic would say. Itachi somehow possesses both weapons, at the same time, hiding it somewhere it can’t be seen-even though you can see everything and there’s not single mention in the description of the technique itself- thus he is merely choosing to use his spirit weapons at all times, right?Your theory is nice and all, but not when its been stated that the weapons didnt come with susano, but its the same weapons that oro was looking for. Also i wouldnt call what i stated a coup out. Itachi is op enough having legendary weapons and then susano's other weapons makes him even more op.
In the manga it doesnt state that you need amaterasu and tsukuyomi.
Secondly as i told you if you look at the databook entry for tsukuyomi it talks about time and space which again is only confined to itachi.
Also, where can I read the weapens didn't come from a previous susano'o?
You're off your game lately.
