there's only a small part of the OP that foreshadows it, but then the ED summarizes the entire series up to that point which of course they only do when a timeskip is about to happen. Mainly there was a concern that FT might take a break before the timeskip because of how close they are to the manga, but it looks like they're going to go ahead with it
