It's curious how there are currently two constants in this manga with regard to the female characters:
-First, there is almost always a constant that they are all abused or have a sex scene.
-Second, if they are attacked by an insect, there must always be a sexual connotation, whether they are caught in suggestive poses or suffer an attack that simulates penetration. (I think the only ones who die without being sexualized are the teacher and that student from the first volume and, so far, Suzuki's friend Misuzu.
It won't be long before both elements are mixed together, although at least it knows how to please the audience of this series since at least the female characters have attractive bodies (although it doesn't help that they are all high school students).
