I legit don't know why I didn't reply to this a year ago but for some reason I found myself watching this video again (it was instantly added to my favorites) and watching it again and watching it again and --

I may have a problem.

Battle Tapes released one other video I've been able to find using those characters. I've managed to track down a short video discussing their creation, by either the artist or the video editor (it's unclear to me).

I need more. I don't know their canonical names, but ye gods do I want to see a show about these ladies.
