Uno Saki is a 15 year old girl trying to make it (unsuccessfully) as an idol singer. One day, on her way home from a concert, she notices a violent-looking man trying to break into her home...
I spent a long time as 
a magical girl after that...
قضيتُ وقتاً طويلاً كفتاة سحرية
...من بعد ذلك
Und seither bin ich ein Magical Girl.
Desde entonces hice de magical girl.
Desde entonces hice de magical girl.
J’ai été une Magical Girl tout ce temps,
sans en parler à personne.
E da allora sono sempre stata una maghetta.
Eu passei muito tempo como 
 menina mágica depois disso...
Я долгое время была девочкой-волшебницей...
