Fun theory about the title of the series
I imagine the creators meeting in a bar.
A couple of drinks in, one of them says:
"Hey, let's make a show!
It’s about a
FOREST,
ORIGIN,
REINCARNATION and
MONSTERS."
"Cool! What do we call it?"
"Yeah, let's just call it
F
R
O
M
for now and find a cool title later."
"Sounds good."
