Genjutsu is one of the 3 main categories of jutsu in the shinobi world and yet it seems to be exclusive to Uchiha or those with sharingan for the most part. Only other example I can think of is Tayuya and some of Jiraiya's tricks.
IDK why genjutsu is even a thing the illusions they make are so unrealistic even for their world
Cause it doesn't work like an illusion does irl(case in point, kakashi and tsukiyomi, knowing your In "the illusion" doesn't really
Help unless it's a basic b tch genjutsu)
Well I disagree it does work like an illusion thats what they describe it as and if you realize you're in it you can break free apparently only ocular genjutsu can't be broken (kishi **** riding sharingan)
That's what I mean though. Most of the genjutsu we see is ocular based. Regardless of whether the illusion looks realistic or not whoevers caught is screwed without someone else around, that's why it's a thing
