Ep3: entertaining and effective (effective as fanservice, I mean.) And as
Midonin says, they are doing it without nudity. And with lots of enjoyable silliness.
All the seiyuus are doing nice work. Chihara Minori delivered Anasatasia's lines with very nice driness and timing. Ousaka Ryouta is a solid harem lead, sensible and straight. And Kito Ibuki keeps unpacking a storehouse of talent. Even that long flat screaming worked. And I especially like her sudden drops from cutesy to seriously commanding.
As for the three-second rule -- which I have heard of as a
five-second rule -- it has been proved untrue
experimentally. But maybe it depends on the floor: a few extra bacteria may be good for stimulating one's immune system, lol.
