I wonder if transforming into the Demon-form like Jackal did and removing the limiters like Sayla did, could be two different things.

It would be interesting if the other Demons also had this limiter-removal, but couldn't use it on their own.

Maybe that's why Kyouka is going to wake E.N.D. because he could force all the other 9DGs into this unlimited state.
