Chiyo-chichi appeared in Osaka and Sakaki's dreams, without the two ever being shown discussing him with each other. Both also dream of Chiyo using her pigtails to fly on the same night, again, without discussing such with each other. Chiyo is only ten years old when she starts high school, but is the top student at the school all three years she is in attendance. Her parents are supposedly very wealthy, but they are never seen. The only explanation is that she is the offspring of some horrible Old One, one that takes the form of a floating cat.
