Akane Sakurada is the fourth of nine siblings in an ordinary-looking family, except their father is the king and each child was born with a unique power. The public will one day vote among them to choose the next ruler. Akane's own gift lets her control gravity, though she'd rather stay quiet and out of the spotlight than compete for the throne. The family's every move is watched by security cameras posted around town, a constant reminder that their ordinary days aren't quite ordinary.
