I Can't Become a Fairy, so I Can Only Become a Magical Girl

"I heard there was a fairy who was as beautiful as heaven." "The fairy looks about fourteen years old. She is dressed in a gorgeous dress that is full of splendor and looks like it is not made in the world. Her hair is as long as ink, her skin is like gelatin, and her brows have a hint of coldness." "He is holding an exquisite staff in his hand, and the gem at the head of the staff is faintly glowing." "The most surprising thing is that under her seat is a winged lion. Its body is made of gold, its wings are spread out to more than ten feet, and it is majestic." "The fairy waved her staff gently, and the evil corpse turned into a card, spinning and flying into her hand. She put the card away, rode the lion, turned around and disappeared into the clouds." "The fairy's title seems to be 'Magical Girl'."
