In the ancient city of ancient China, a group of young men are playing chess. One of the young men, named tamamo, is playing with an elephant-horse chariot. The other young man named hiroki, who has been studying swordsmanship since he was six years old, is also in the middle of playing chess with the other young men. Aww, what a coincidence. The young man thinks that his opponent is a little girl named joanna, whom he has just seen in a picture. Ooh, that's right, he's seen the girl in the picture. He's also seen her in the chess game, so he knows that she's not a kid anymore. He tells the young man that he can kill her with his own hands, but he can't because the old demon is lying to leave. .
