what makes you think its mary sue ?
This Character's personality :
- cheerful
- happy
- loves to cheer and play, and go out to party
- dependent on others to survive because she's inexperienced.
- sometimes may not understand consequences of her action
i just don't see why the qualities above is a stereotypical Mary Sue.. this is actually Archetype based from Greek goddess Persephone... if you think she's a dumb blonde like one you get from Dean Yeagle's Mandy Characters, you're greatly mistaken...
