Not super certain, but it seems that that...thing (what the hell is that?) she's holding should be white(?).She calls out for "Yukarin-rin☆" for some reason and tosses the thing in the gap ("Ei!") when she appears. Not sure what the fourth frame indicates, but the fifth is telling me something like "shocked to blueness by cuteness." The last, of course, is Yukarin having her way with the miko. Marisa (voyeur) is saying "This is kind of hot..."
If I were feeling ambitious instead of tired, I'd try looking up the stuff I don't know, decipher the scribble glyphs and, you know, actually think about it a little at all.
