Over on the Japanese website for this series, a series of chibi clips called Mijikamon are posted. However, they do not seem to work in certain territories.
Is there any chance of them being added to the set of Barakamon clips here?
It really depends on rights issues.
If anything, I could see them being added to the eventual home video release (provided FUNi doesn't make another screw-up like they did with Senran Kagura -_-).
Oh man, I really hope these make it to the Home Video release when it comes, it'd be a shame to not have them with the main episodes for posterity (also so that we can actually watch the shorts).
