If you mind spoilers, pls scroll away.

I have a LOT of theories coming up and I cannot post them all at once (not even in parts!) so I will just put points about my theories and you guys just comment on what I can say about it.
Consider these questions:
Who's Elyssa?
What's with Natsuki's father?
Who's the girl with whited out eyes in Natsuki's chr file?
What could be Sayori's role in the new game?

Okay first this:
1. Who is Elyssa?
Elyssa could be the girl found in Natsuki's chr file.
Now Elyssa can be one of two:
A. Yuri/Libitina's mother.
Because it can be seen in the Project Libitina website the quote "Libitina won't be recovering anytime soon with the termination of XXXXXX." And I guess XXXXXX stands for Elyssa? Also we don't really know much about Yuri's family/relatives so that would be the closest reason why.
B. Natsuki's mother?
Natsuki is malnourished because her father doesn't give her lunch money and cook food, or atleast not that much. Wait, where on earth is her mother? That question BOTHERED me a LOT. Remember I said that Elyssa could be the girl found in Natsuki's chr file? Yeah that's why the picture is found there!

What about both? Because Natsuki and Yuri (although I won't support this theory) could be sisters. I mean, they fight like one! XD

2. What's with Natsuki's father?
Now because Natsuki is malnourished we can say that somehow her mother is gone or also is working. What if her family also was in the religious-camp-turned-human-experiment-lab? Could Natsuki's father play an important role in Project Libitina?

3. Who's the girl with whited out eyes in Natsuki's chr file?
Easy, Either Elyssa, Natsuki's mother, Yuri's mother, or even 2 or 3 of the 3! (3 of the 3? What?)

4. What could be Sayori's role?
I've been scraping my scalp just to answer this really hard question...
So here's mah take on dis:
Natsuki and Yuri can be related or have met somehow in the portrait of Markov and... Sayori... eh... she doesn't really or atleast for now clearly fits in... but still Sayori's role could be very special.

So yeah just ask me more of my opinions on these questions I put out. Of not satisfied with these add more! Lemme know what you can say about this... and yeah my mind is messy so just go ahead ask for a little clarification. And as always chillax boys! It's just a theory!
