Honestly, this isn't worth watching unless you've seen the full series and even then, don't watch it. It doesn't add anything new to the characters and is just fanservice (which can be fun, but in this case, it did not leave a satisfying feeling. Also, unnecessary beach trip episode featuring sexual harassment & groping of characters + predatory lesbian trope! Awesome!).
Bad bad bad bad bad & the original ending of the anime is so much better (even though that still wasn't great), so please, don't even watch this. It will not make you feel anything but mildly confused and upset.
