Unexpected blond Kasumi, flashback maybe? but nice to see the kouhai couple. For as much of a glutton as Kasumi is, I'm surprised we haven't seen the hamster cheeks gag before now, but I'm happy for it. As disappointing as it is that Shouko picked up smoking, at least she's considerate (seriously, going far enough that even her girlfriend can't pick up the noxious smog that permeates everything? that takes effort!). Not sure how to feel about Seri liking it just because it's Shouko's brand, though at least she doesn't seem like the kind of idiot to copycat.
