I wonder why Kishi hasn't bothered to tell us even once that he has Tsukiyomi. Whenever he uses Amaterasu, Susano'o or even Enton, it's always noted somewhere. But when he uses his MS Genjutsu it's just said that ''That genjutsu'' or ''It's a weak illusion'' etc.There are arguments for both tbh and we still havent seen madara's other ms abilities.
The way susano has been described in the db its in relation to itachi and the same can be said about the description of tsukuyomi.
Tbh kishi is playing around, im now confused about tsukuyomi what exactly is it. Is tsukuyomi the genjutsu that madara used when he activated the ems on A, the same genjutsu that sasuke used when he activated the ms on danzo and bee. But in itachi's case he has gone a step further with the technique and has shown great mastery with it and can manipulate everything in that world. This could also back the fact that whilst sasuke is better with amaterasu and can use blaze release, itachi is better with tsukuyomi and can mainuplate everything in that world.
Or whether tsukuyomi is the ability to control everything in that world therefore anything else which doesnt do this isnt tsukuyomi, but rather sharingan genjutsu
