>>108768152Fuwamoco are almost certainly virgins. They have been idols for years and are very committed to the idol dream and to their fans. Maybe they hooked up with a girl because they don't see it as breaking their promise, but twins are notoriously difficult to hook up with.
Gigi is almost certainly a virgin too, she's asexual, maybe she tried it out once and wasn't impressed.
Kronii is a toss up, she's very hot irl, but on the other hand she's very shy and awkward and keeps falling in love with straight women.
Bae is also a toss up, she grew up very sheltered and isolated. Also the kind of men she's into are rare in Australia.
Cc is obviously not a virgin, but she probably has only had sex with women.
The odds for the rest of EN are not good, maybe Sana. But I don't know much about her. It's not impossible for the rest though, the only confirmed non virgin is Nimi.
