You obviously have a clear direction you want this series to take by the writing style and video effects, but I gotta say for this "prologue" you didn't do a good job setting the stage for anything. I have absolutely no idea what this is supposed to be about.

Also there's some conflicting dialogue that makes it more confusing:
"A demon entered the village"
...later...
"Did you say it was machines in the village?"
"Yeas, why?"
That doesn't make sense.

And also:
"Take the pups to an orphanage"
...
"Just do as I said"
...
"Just take the pups to the school"
There wasn't really a visible shift where the (what I assume is a protagonist) changed it's mind between these lines so I assume it might be a discontinuity?

So yea, in summary, looks like a lot of care was put into making an upcoming series, but from this prologue/teaser alone I have no idea what it's about(after watching several times to be sure).
