Interesting crossover and on the end card.

Actually, you can see that coming as early as episode 1 end-of-episode illustration.

The collaboration with Kantai Collection has been in the ending credits since episode 1, too, so yes, it's been going since the start.

Though to be precise, the kancolle-esque illustration in the end-of-episode illustration of episode 1 depicts a more historically-accurate version of I-400 class subs.
