Having to be friends with a chain-smoking, class-skipping, hell-raising juvenile delinquent isn't all that bad, although she's pretty much the last person on Earth you'd expect to be a magical girl...
A little girl with some of the richest parents in the world, a massive mansion, her own personal maid, how could her life not be perfect? But having a abusive mother and no friends means it worse then you think. Until she meets a mysterious forest girl who has nothing becomes her first true friend, everything becomes happier. Until she realises that happiness is be short lived.
