Why are Flan and Kokoro shocked by this? They're youkai. This is pretty tame by their standards.
Flandre is a pre-adolescent vampire who gets all her blood in the form of drinks and pastries. Kokoro is a menreiki, literally just a bunch of animate masks not known to do anything worse than float around and be spooky. And I really, really don't know what kind of comparison would make this "tame", even next to eating people like some youkai do.
