Hmm. It's interesting that this game has her diary already start out pre-filled.
I don't know if there was supposed to be a prequel or something, but there's comments in her diary about being caught staring at an orcs dick, after defeating it, or getting slimed and having to be rescued by another magical girl.
Plus, the first enemy in the game... if it catches her, she just sorta says "Well, it feels good and it's not attacking, so i'll let it continue for a bit."
Normally magical girls are 'purer' than that. It's neat that she's already kinda lewd.
