Gensokyo's Humanity has declined

Artbook picture I did for the 2013 edition of the Touhou.ne www.facebook.com/TouhouNet artbook!
The theme was to do a cross-over, and mine is a Touhou X Jinrui Wa Suitai Shimashita one.

I wanted link the fact that Reimu is always bugged by Youkai to the way the Protagonist has to deal with the fairies. (Except Reimu usually resolves troubles with laser beams, but.... yeah)

All the main characters from TH06 to TH013 are in the background as fairies... Or that's what I thought until today, because a major one is lacking! That's even a fairly popular character...

So, let's do a little game, if you find who's missing, I'll give you SOMETHING GREAT. *Tadeshi won, it was Alice.

(Humans character does not count there, as you can imagine them as the human cast in Jinrui. (Marisa being the old man and Sakuya the fujoshi, or whoever you like.) So Marisa, Sakuya and Sanae are not the answer!)
