With Crunchyroll's diminished release slates I'm amazed at the Dragon Maid movie getting a release--even when Crunchyroll and previously Funimation had large slates, far too often movies connected to TV series never got home video releases, Date A Live Mayuri Judgment being one notable example of one forever skipped over, and as I understand it, it's an important part of the story between two seasons of the series; I can't verify since I've never seen it since it wasn't released.
I'll buy Dragon Maid, UK if it releases here; US otherwise. There's nothing else in that set of releases for me though.
