Everything has a balance.
The problem Fang Zheng is facing now lies in this aspect.
Don't be fooled by how Little Sakura and Nanoha, the magical girls in their world, seem to live leisurely and happily, because as magical girls, they also have obligations to fulfill and trials to face.
If Little Sakura fails, all those related to the Clow Cards will lose the memories of their "most beloved person."
If Nanoha fails, she'd end up paralyzed, possibly never soaring into the sky again for the rest of her life...
They only gained and mastered the powers of magical girls by passing through these rigorous trials. Of course, if they succeed, all is well, but if they fail, the scenario immediately changes.
