@Squinty
 * Well i counted the individual bits of amaterasu flying off the Uchiha Hideout, 4 of those plus the one against the katon (5) then the seal (6)..
 * It's not really headcanon as it is shown. 2 tsukuyomi + 1 amaterasu = deactivated sharingan. Here 1 tsukuyomi + 5 Amaterasu = still active sharingan. So it's pretty clear
 * Not sure techniques work like that, you weave the sign and after hours of using a bunch of other seals and jutsu you can still activate it? dunno about that.
 * Arguing why the character did this but not that is kind of meaningless as it's already done lol and the purpose was clear given the contents of tsukuyomi he showed Izumi, and also considering he kept on going with the slaughter means it wasn't as taxing as your making it.
 * Meeting Madara? that's the same "Madara" he gave a death threat to, so clearly he didn't give a shit about Madara.
