The nine Sakurada siblings live an outwardly ordinary suburban life, except their father is the king and every one of them holds a superpower. The fourth of the nine, shy Akane, controls gravity and dreads attention, which is a problem: thousands of cameras track the siblings around town, and their father has called an election to decide who inherits the throne. Each campaign plays out in public, leaving Akane caught between her wish to be rid of the cameras and her terror of the spotlight that running would bring.
