GP Reference: Detective Hiyori's Case File

Note: These are his IC notes based on his own experiences and observations, plus information he's gotten from other characters and NPCs. Most of the information is factual, but there are some erroneous assumptions here and there (like his assumption that everyone got the same "You will play a game, you will benefit" message during the Springtime event; he never spoke to any rabbits, so he never learned otherwise). Then there are some baldfaced lies, but those all concern himself and the Enstars cast rather than the game setting. (He repeatedly insists that none of them have voluntarily played Game 52, for example, but he's just saying that to protect their reputations.)
THE ALTERNATE ROOST?
"It's unlikely he ended up stuck in the Alternate Roost, then."
And then, when I asked what on earth that was:
"Oh, you didn't visit it? Probably for the best. It was full of unpleasant ghosts and life-draining energy. I wouldn't recommend it."
So now there's something else to investigate! Not that I want to meet any ghosts, or that I want my energy drained. But just what on earth does all that mean? How do ghosts factor into everything else going on around here?
At the very least, I feel like I should ask around about it. Which is troublesome, since I already have so much else to do. I simply can't wait until the day I get to hang up my detective cap and leave this place behind. I thought being a detective might be fun, but nope! It's mostly just frustrating!"
