Matsumae is a girl who loves to daydream. She lives in her own little world until she meets QB. "Please make a contract with me and become a magical girl!" What suddenly appeared in front of her was a miracle that was within reach. She hesitated and was uneasy, but in the end she couldn't withstand the temptation... Made a wish, and then became a magical girl. With the idiotic idea of 'protecting the world', she started fighting. But in fact, magical girls are just vessels that breed evil and dark witches under their beautiful appearance. This is very much like her now, as if something has deteriorated. Under the bright and bright appearance, the inside is rotting and smelly.
