This thing continues to bother me ... is her hair back to normal, exactly 12 o'clock in the morning. as you can see, she cut her hair. importantly, it is short. then, did she go to school wearing a wig ..... or what?

Yeah, I assume so. It'd make sense, since her female body should be the original. Based on how the male body seems to have muscles to begin with, I'm guessing it reverts to a similar structure each time, despite the female body being capable of developing. I also think this is why the female body goes back to how it once was, since it has to revert back to its last, most developed, state. Ah, but I could be wrong.
well, she will grow heavier, taller, and maybe that "thing" will growing too (ββ½β)
