Hostor, is the newspaper only about murders?

Well, for now, yes. Maybe something else will be added later...

Hostor, by the way, if the killer kills again, will there be a 50% chance of revealing the role of his victim?

Yes.

Why was Imaris's role revealed?
It's clear about the Mafia and the Commissioner – based on their abilities, but why Imaris?

Since the Mafia and the Commissioner have snails left, and Imaris was killed by someone obvious, I'll answer.
Question: Roles are not revealed when there are 10 or fewer participants left. But if there are 12 participants left, and three people have died, whose role will be revealed?
Answer: The priority for revealing roles is as follows:
1. victim of the Mafia
2. victim of the Serial Killer
3. victim of the Commissioner
