Not sure if a real fansubbing group has picked this up, but the version I watched was machine translation and it was rough, though I think I was able to follow it mostly. There were also many times I felt like I was supposed to be already familiar with the premise, the characters, and sometimes even sword history. I'm sure this is all very interesting for fans of the series, but I don't know that this is a good entry point for newcomers like myself, despite what I've heard from some fans. It also has the same problem that every touken ranbu anime has had (in my experience), which is that there are WAY too many characters. On top of all that, the cgi monsters in the opening don't bode well for future action scenes.
As a starting point in the series, I give it a 2/5
