All in all, Natsuru's school seems to have a problem with rampant lesbianism.
Episode 3 loves this trope; upon female Natsuru's arrival to the girl's side, the collective reaction of her new female classmates is to perform what is essentially a large, simultaneous group-glomp. Following that, the remainder of the episode features nothing but the rest of the school's female population depravedly fawning over her, with a few even going so far as to capture her and tie her up so they so they could play with her as much as they wanted.
Kaede towards female Natsuru.
The Assistant Committee Chairperson is a little too attracted to Natsuru's female form.
