I demand Ao Usagi makes more Patchouli and Koakuma pics like this (with a bit more of Koakuma), and he should also make some Byakuren pictures. That aside, I don't think there's air conditioning in there.
Ao Usagi said: The Great Library is in the basement, so the ventilation isn't very good and it gets stuffy. On top of that, there's nothing but women in the Scarlet Devil Mansion, so they don't have to worry about getting seen by a man. As a result, I think this sort of scene must definitely unfold in the summertime. Eh? There must be some kind of magic that does something to counteract the heat...? T-that's... nuh-uh!
