I've been coveting the idea of a story in the Nasuverse that doesn't spin around Servants and Holy Grail Wars for quite a while.

However, it's hard to say that I'm interested in this for sure until I know what it's about. I'll be on standby, in case there's an explanation that I like, I'll join. But until I see anything more than "this isn't Fate", I can't say anything else.
