Transform into a Magical Girl

What is a magical girl? As everyone knows, magical girls are a high-risk profession. Some people think that they are the embodiment of happiness and hope and the saviors against evil beasts. Some people believe that they are the source of disaster and that they bring about terror from outside the world. But to Ai, the time traveler, magical girls are just a group of problem children who need to be protected, a group of fools who try to burn themselves to save others. Therefore, Ai, who became the guide spirit of magical girls, decided to protect these magical girls when they were in danger and be a mature and reliable adult. But don't ask these problem children why they became magical girls. Don't ask why magical girls are in danger. ／◕‿‿◕＼
