Fifteen has been locked up in a dungeon for as long as she can remember. She kills people, eats, and bathes in a green pool every day. She doesn't even have a name. Fifteen is just the number on her clothes. Until one day, she is bought by someone. The person who bought her is a young man of the same size as her. He gives her a name - Fei.
He said, "If you walk on water, you will die; if you walk on grass, you will die; if you see it, there will be a great epidemic in the world. I want to be the master of the most evil thing!"
From then on, under the leadership of her master, Fei lived a life of crazy and cool cocks.
