Well, if there's one idea I'm sure about, it's that bracelet of Sakaki's.

On the bulletin board, it tells us how many VIPs and roles and regulars are alive, right? And they had--Kuzuryuu, they had his name there. That was when we could all learn at the same time he was dead and a... an innocent guest without a role or anything.

But for Sakaki, there was no loudspeaker or anything. We just heard the noise and followed that. So that's why the bracelet was programmed to tell us what his deal was.
