Ok I now understand where you are coming from, there are a lot of people in that same place of not being able to separate the game and reality in these issues. Those same people tend to have the same reactions to in game rape scene's, they either have no problem with it or they have massive problems with it.

Personally I think Wax Tree looks adorable and her sprite when she makes attacks and special attacks just adds to that.
On your point about her not being 10+ years old and I get that you are not going to change your mind, but having seen her H scene pics (thanks to the thread here that players have created for that purpose) she's less of a child than Christmas Rose. Make of that what you will.
