(Possibility) Game Theory?

[AceSpaceErase]

Is anyone remember the girls sorority club's name? With Pi something something that I can't remembered well

I just realized when I enter Sheriff's living room, and there's Pi symbol (π) in the middle of the room.
Back to the inn, that P letter is something called Rho symbol.
These are Greek letter and for some of you must be familiar with this.

Somehow, looks like Davis (Sherrif guy) has important role in this case since he feels unsafe and run away prior main characters arrival.

And for the British Detective and Sam, those two are uncercover agents or something like ghostbusters (I don't know, is this game supposed to be horror genre?)

Any ideas, enlighment, clues, or something to add up here? Comment here, guys.
I know it's too early too digging up some clues bcos it's still EP1, I just want to know how far the dev leave clues to us to find

Hi! Wow! I also noticed them, but thought Greek P is TT maybe.
I suspect some people. For example, tyhe first thing that comes to my mind is any vampire or werewolf. Maybe someone whom we don't know. In other hand maybe someone whom we know. For example, Davis, Philip, the girl Philip met at the hotel in the end, Hill and the concierge.
I don't think this game has too deep story as anime/manga stories. I don't mean this game is bad. This game has great and interesting story in Chapter 1. I didn't play others yet.
But I think if murderer is out of whom I listed above, then he/she is Davis, the girl's Philip met, Hill and the concierge. Especially, the concierge is suspicious.

Also, don't forget to watch my video about this game.
