People underestimate the Magical Girl. They either think them soft because of their mercy or weak because they are usually mere children given comsic power...

Neither is correct, at least for any who don't dig deeper.

Mercy is not weakness and any who think so are the most deserving of it, even if they would reject it. Mercy is not the same as forgiveness, it is an opportunity to make up for it. While some are more childish than others is it not a miracle that despite what you have done to them and others they offer you a chance to be better than the being you were before?

The Power is given to children to teach them this; adults tend to be too... what's the word? Cynical. Some can hope, some are still children at heart yes but growing up removes perhaps the most human part of us, the innoccent part; that their is such a thing as good and anyone can try. Some children can be cruel, mind you, but that does not mean they always are nor that they cannot be better.

Is that not what it takes? - Glynda, Goddess of Dreams and hope
