I don’t believe the first 2 OVAs are licensed in the US. I watched them on Youtube, but the picture was only about a third of the screen and terrible quality. I was hoping they would be extras on season 2 or 3 disc release, but nope. A shame because I enjoyed them both.
I haven’t seen the 3rd OVA. I suppose the movie really wasn’t that bad, it just didn’t feel all that special because the awesomeness of the tv series spoiled me. I was also feeling over hyped because it was the first time I’d seen a non-Ghibli anime in a theater.
Edit: seems I was wrong. Don’t see the third OVA listed as an extra either.
