To clarify, Yin Release's specialty refers to the "primary methods of release" in its specialty description. As per the Genjutsu rules and Method Training written by Reborn a couple of years back, this has always meant either a chakra surge, foreign injection of chakra, or pain. These are the three basic methods of release that are universal to everyone, which is what makes them primary. It would be strange if we included methods in this categorization that would otherwise not be universal, like Sharingan.
Even if this wasn't the case, and we treated Doujutsu as a primary method of release, Rinnegan still possesses an immunity to all visual illusions. That also means the visual component of an illusion, if there is one, would also be ignored. It wouldn't work in the first place.
I'll give the ruling quick. This illusion doesn't work regardless because of the Rinnegan's visual immunity; at least in the way of Madara and his Limbo clones. The illusion might have some "tai" aspects to it, insofar as body motions and taijutsu, but its still visual at its core. Seeing yourself shatter is visual, and the effects that would come with that are visual as well. And this idea of separating mind from body isn't even in the technique at all. Shattering mental realm isn't defined. It's really just taking creative liberty in defining what it is for convenience. Madara would, at best (if this worked), suffer 60 damage. But in your argument you describe it as essentially being a vegetative state (see below). That's a huge overreach on terminology. A sensory numbing effect isn't really defined. But from what I gather it would basically just disable your opponent and disconnect them from their senses. Ergo, a vegetative state.
"Madara has his mind shattered within the illusion, disconnecting it from his body, which is nothing more than a Paralyzing effect mixed with a A-sensory or Sensory Numbing effect, both recurring effects from Genjutsu."
And even if Madara did get trapped, the clones are just going to absolutely lambast Isabella. Since she has no way to perceive the Limbo clones, then there is no way to trap them as well. They're free to rampage. But other issues I'm confused on are how this technique is trapping multiple people in an illusion in the first place. Genjutsu are restricted to a single target unless it explicitly states that it can influence multiple people in its description. Even the description of Shattered suggests it is a single target illusion because it refers to "the target" and how you land up to 6 strikes on them. But this is secondary to the main problem here: the Limbo clones and immunity.
So yeah, there you have it.
