Few things linking this series to Barakamon are 3 Characters and Calligraphy(not even overly implied).
That aside, the anime itself is not bad even though there's not much of a story(there is, just a different one). I still enjoyed it due to its comedy.
If this was a standalone series. I would have rated this differently since its fun to watch and "kinda" resembles a certain show aired during Spring 2016.
Overall 6/10
