Okay, so it's not Castlevania. That explains a lot.

Thanks guys. It's a really beautiful scroll. We thought it a shame that it was the only scroll we didn't have a story about. Maybe some digging will reveal more about its purpose (if any).
Yeah, Ayami Kojima has drawn plenty of stuff in this style. May I ask where you work? I've seen this drawing many times but I've never seen it as a scroll like that. Cool!
I work in a little nerd shop near Austin, TX in Lakeline Mall called Gamerz. If you're ever in town you could totally stop by! We have tooooons of scrolls. This one we actually get regularly.
