I don't know. I said in my last post I haven't seen it, I just said what I was told...besides I didn't know the guys surname cos I've only seen the first film once or twice...and the first 2 or 3 eps of the series bored me when I watched them...though I guess I might try the series again some time...

I've just searched the animenewsnetwork and found this quote which says that it is considered by some to be a sort of sequel, but that it isn't actually related to the film.

"Hailed as a pseudo-sequel to Ninja Scroll of sort"

another quote

"This OAV has nothing to do with Ninja Scroll at all. It's not by the same director, it's not by the same production house, the characters look different, the time period is different... in fact, the only connection between the two is that there's a character named Jubei. Jubei isn't even a main character! He's just one guy fighting. I couldn't even tell what side he was on! While I can understand ADV Films wanting to milk the market that got into Ninja Scroll, it's not the only marketing inaccuracy: It's less than 40 minutes long, while the box says it's 50."
