All good things come to an end, and what an absolutely beautiful ending this was, this OVA concludes almost all the remaining adaptable material for Non Non Biyori and delivers an excellent stand alone episode for this series. While I do hope this series gets more content one day, I am pretty satisfied with everything we got.
The pristine and photorealistic art is in full display, possibly even better than the main series, really bringing to life the amazing Japanese country side in all its splendor. Animation quality was also quite solid, the badminton scene had surprisingly fluid animation, reminded me of the movie.
Sound design is still quite enjoyable with a very tranquil and immersive entrance and consistently effective background sound effects that bring the countryside to life. The splatter of rain and the light whistle of the wind, the sliding doors in the school, the footsteps in the class, all of it are just so wonderfully done and perfectly complement the scenes they accompany.
Getting to see our favorite cast one last time was excellent as well, quite happy Shiori was included and Renge is always a joy to watch. Every main girl got some screen time and at least a single highlight moment.
Overall this OVA concludes the series in a happy and mundane way, true to the rest of the series and fits perfectly with the general theme of a wistful country side life, solid 8 out of 10 and I would highly recommend it.
