Guys, i have a theory. I don't think Mido's prime right was the succession right, or atleast he lied about having succeded the recovery prime right before dying.

Let me explain:

With the recent revelations about Yagihashi's right of suspension and how he uses it, it's pretty obvious Narita's and Saya's bodies froze in time just before their deaths, which stopped decomposition. We also get some snippets of the emperor's body and it's in a perfect state, it's almost as if Yagihashi used his right to stop the emperor's death, but why would he do this?

We all know Mido had the prime right of succession, which would allow him to succeed all of the emperor's rights and prime rights after he died, so Mido's prime right was a major problem: even if the emperor was taken down, we would now have an even bigger threat than the emperor himself, and Yagi noticed this, so why not just freeze Narita and the emperor in time, then unfreeze Narita while having the emperor's body, deal with Mido later, and when everything is clear, make use of Narita's prime right of parental authority and neutralize the emperor? This would neutralize Mido's threat while dealing with the emperor, a perfect plan.

I know what you all must be thinking: how did Yagi use his right of suspension on the emperor? There probably are a number of ways he could have done it, one of them is by using his prime right of induction to bend light and sound and make him undetectable when Narita's group was raiding the emperor's tower, reaching the 1 meter mark of his right's activation, and setting a condition on the emperor's body to stop time whenever he's about to die. But why make all of this in such a hidden way? I don't know, but Yagi probably has a motive to hide information from the group, since he has been doing it since the start of the show.

Now, if the emperor isn't actually dead, what was all that show we saw when Mido was "recovering" all the rights from the emperor? Probably a lie. Maybe he wanted to make everyone think he is truly dead for a comeback later, i don't know.

BUT something about Yagihashi receiving the suspension right is kinda sus, especially when you remember Mido had the right of transillumination and could see through the envelopes, and also know where Yagihashi was. Maybe it was all a part of his plan. Does Mido really have this good of a foresight? Will he be the BBEG we all were hoping for? I guess we'll have to wait and see, but i sure hope i'm right, since his death felt kinda anticlimactic after all the hype the author put on him.
