How to become a magical girl:
Those chosen by the world will become magical girls
There are three necessary conditions for being selected:
1. Females aged 9 to 17 years old
2. Possess the necessary qualities to use magic (i.e. the three principles of magical girls: justice, mystery, and purity)
3. Have the desire to become a magical girl
4. On this basis, priority will be given to beautiful girls.

Age limit for magical girls:
Only women between the ages of 9 and 17 can become magical girls, but after becoming a magical girl, in theory, they can continue to serve. However, in reality, as they age, they will gradually lose the necessary qualities and lose the ability to use magic.

So in reality, the golden age of magical girls is usually 15 to 23 years old. After the age of 23, their abilities usually decline significantly, but there are a few magical girls who can still maintain their power after the age of 30.
Magical Girl Transformation:
With gorgeous action performances, she transforms from an ordinary woman into a magical girl.
The magical girl is invincible during the transformation and theoretically cannot be affected or interrupted by anything.
Transformation speed: The transformation time is about 1 to 15 seconds. It takes a long time for beginners, but it will become faster and faster after getting used to it. There is no need to memorize the transformation movements.
The combat type transforms the fastest, the fantasy type is second, and the sealing type is the slowest.
The magical girl's power comes from the world, so she will not feel tired even if she transforms many times, but there is a hidden setting that she can transform up to seven times in one day.
The Prayer System is quite special, as once transformed, it will exist in the transformed form for life and will not be released, so the Prayer System is like a lighthouse and cannot hide itself.
