With the word "Presence" typed in italics, and the general nature of what this series seems to be about, I couldn't help but be reminded of the Robot Carnival short of the same name =03(CC for subs)
Yeah, I remember watching this way back in the mid 90s on the Sci-Fi channel. Unforgettable because it was the first anime I had seen up to that point that made me tear up and cry, even though I was only like 12.
I'm hoping this series can decently evoke a similar feeling that the RC short did.
