Non Non Biyori is always great at eliciting a range of bittersweet emotions along with an incredible sense of calm and serenity...plus just enough humor to keep things fresh and unsentimental. This OVA is no different, and my only disappointment is that we may never get any more stories from this incredible little country town. The first part of the OVA is devoted to homework, and the second to Nattsun's desire to start a badminton club. When you find out why she was inspired to do this, it's an especially sweet moment...but then again that entire half of the OVA is packed with great material.Not every character gets to shine in this single episode, but there are lots of cameos to at least ensure few characters are overlooked or forgotten.
Stay until the very end to get a small ray of hope.
It's always sad for anything in Non Non Biyori to end, but don't forget that you can watch everything again from the start. This OVA means that you have one more small gem to add to that rewatch list, and for that I'm thankful.
