Board Thread:Theories and Speculation/@comment-43776375-20190929185011

I made a previous post on the intagibility of kamui, the reasponse was actually in the wiki, just divided:

"Obito can also use the right Mangekyō to temporarily transfer all or parts of his body to Kamui's dimension. His body (and anything he's holding) will remain visible to others, but they won't be able to interact with him. Obito often uses this ability defensively, transferring his body to Kamui's dimension so that attacks will harmlessly pass through him" ... "Alternatively, Obito can make his entire body intangible"

Is was the alternatively that confused me, like it was already said before he could tranfer all his body to kamui dimension but remain visible

So given that, my idea is that while kamui is active genjutsu can't work on obito, the thing is kotoamatsukami manipulates the chakra of the mind of the target, but to do so you need to use your own chakra, but if obito is intangible then your chakra can't reach him, now we could also speculate on a teory on why is obito visible, we could say that only things that travels at the speed of ligth can cross kamui

The key point here is, to use genjutsu you need to reach the enemy with the chakra of your eye? Another fair point would be that creating a ganjutsu with the sharingan just uses the chakra to create an ipnotic pattern on the user eye and this ipnotic pattern unconsciusly manipulates the chakra flow on the enemy, but there is a problem with this, while it can be said for all tipe of genjutsu the sharingan has, kotoamatsukami is special beacause it doesn't require eye contact, but the enemy must be in the field of wiew so seems like shisui sends chakra from his eyes to cast it

Special addition: if all genjutsu works like sending chakra then they shouldn't work on the junjurichi of the juubi and all otostuki, and if one posses the rinnegan he could absorb it, if he knew a genjutsu is being casted
