Basically, monster girls are all demons and tainting the land, and she has no idea about what actually entails fighting monster girls. As such, there was one scene in particular people didn't vibe too well with where you get the whip item. She basically has an (imp?) tied up and is whipping it.
Long story short, she was much more entertaining and it could've made for way more fun scenes if they ever expanded the character and had her realize what's going on. (Or let the pc join her because why not). Instead she just sorta became a generic nice girl who knows what's going on, and while she doesn't quite agree(?) with it she supports the player in their endeavors.
I'm paraphrasing quite heavily since it's been so long and i dont remember her exact dialogue, though. But she was 100% meant to be a bit crazy in the old version.
