There's a Tewi in there for extra mischief it seems.
Also, Sunny Milk, Star Sapphire, and... I can't remember the other one's name atm... also spotted in the Fairy Wave.
Who's that in the top left, (3 in from the side, 1 down from the top row) with the bandages over her eyes? I recognize her, but can't pin down from where.

I don't think that's Rider. Hair is the wrong shade, too short (you can see it end mid-shoulder, while Rider's reaches mid calf), clothes are different, she doesn't have her weapons and blindfold is completely different.
Tsukasa Hiiragi (Lucky Star), Hanyuu Furude, Rena Ryugu (Higurashi), A couple of Tarakos, Lily White, Lily Black, The Prismriver Sisters and Wriggle Nightbug are also there...
"So...are they all pissed off at Reimu and Marisa or something?"
Everyone in Gensokyo wants to sex Marisa. And kill Reimu.
Of course, since Reimu can't die, she just wants to hitch a ride and not waste the one spell card that it would take to kill 98% of that crowd in one go.
