The aftertaste of that episode is especially bitter once you remember that the cat and dog MCs you've had fun watching for nearly a year are no magical beings. Nico makes it clear that the end will come for them, no exceptions.
For Iroha, for Mayu and for Satoru, they will all get to experience what Otsuru went through.

It was really well done, and not just as a standalone episode.
