After reading PJR’s post, I went and look the demo again. But, before entering into details, I will assume that we mean virgins as in “not had, so far, any sexual intercourse”, as girls may break the hymen by accident. So, who could, who could not.
1) Ayumi: just like PJR, she must be one of the virgins.
2) Makoto: I think she may not be one of the virgins, as she does not seem to have any commitment at all (unlike Ayumi). A bit more free-going, IMO.
3) Nanami: Probably not, but not for the same reason as PJR. She may be more of a “normal” girl, and she could have already had such an experience.
4) Kumi: Probably too curious for her own good… A no, here.
5) Natsuki: She is a tomboy. Probably another virgin here. (I am not biased that tomboy == virgin! She may be a tomboy because she had an unpleasant experience)
6) Kyoka: (BTW, Kumiko-san, 24 years old isn’t too old to be a debutante?) I will give this a 50/50. The reason is her “mysterious past”.
7) Yuki: ditto here as with PJR, almost no chance.
8) Keiko: For no particular reason, she seems to be one of the virgins. Probably because of the wormbook look of hers??? ^_^;
9) Misato: Nope, she doesn’t look like one of the still-virgins. Probably because she is a bit more outgoing than her friend Keiko?
10) Mai: Hmmmmm… well, though call, but let’s consider her one of the virgins.
So the tally of the virgins are: Ayumi, Natsuki, Kyoka (giving her the benefit of doubt) Keiko and Mai (ditto).
