Uh oh. Renko spotting ahoy. What's she doing there without Maribel?

Who might the other girl behind Rinnosuke be?
My guess is Isami Asama (http://images1.wikia.nocookie.net/touhou/images/e/e8/Isami_Asama.PNG) because of the beer, skirt and hairstyle, but the shirt has no buttons.

It certainly isn't Yuuka, because she's participating in the tournament.

What's she doing there anyway?

that strawhat in first panel reminds me of someone... but i cant grasp who it is....

Considering the look on her face, I'd say Renko doesn't know what she is doing there herself.

Yukari must be messing around again and pulling renko there out of nowhere

Well kill me if you must,Arnie...
Although considering her ability as a living GPS, it'd be pretty funny if she really lost her bearing...But then again,it is Gensokyo..

I thought of the Watatsuki sisters, Yorihime on the left with her ribbon and Toyohime on the left with the ribboned hat.

And with Renko already there, along with whomever else rather out of place like Isami Asama, why not?

So...is it just me, or does that one audience member in the first panel on the left look like he has an arm growing out of his forehead?
