Will this scene make it into the anime series?
We've already had 3dcg dragons and magical dolphins. Surely they can't keep skipping around all the sex that happens in FSN.
One interesting thing is that they kept the dickworms.
The thing is, the worms were specifically part of UBW, so the rape is at least still implied.
At the same time they've been using fish visuals when showing scenes with Rin's dreams or talking about magic.
I wouldn't be surprised if they do like, a fade to fish, if you know what I mean. They imply the sex, but use the fish as kind of a metaphor.
