Re: the artists post script, there may be quite a few non-H Touhou stories, but not all of them focus on the story as much as this. Not all of them even have a story as well-written as this, so it didn't even matter to me. Ships are cool, a well written story is more important. The whole thing centering around doppelgangers was cool too. I've always been really interested in the whole lore, modern interpretations, etc. of doppelgangers.
