Hmmm... that's actually not a bad theory! Wow!

When I think about it, Shisui's eye didn't go blind, it was rendered unusable for a decade, right? And it says on the wiki that Shisui could cast other powerful genjutsu with his Mangekyo, with Kotoamatsukami being the most powerful. So, he had more than one.

Maybe Kamui and Kotoamatsukami don't take vision away.

Of course, this trashes the theory that Obito was talking about the Mangekyo going blind instead of the eyes not being a lasting gift. Which would suck. So idk. Cool theory though.
