In the kingdom of Sapientia, it is the women who rule: men are merely slaves who serve them. Every year, rich young girls select breeding partners from among the winners of a gladiatorial tournament. Adona, the daughter of the event's primary organizer, doesn't feel ready to take part in the auction. But she needs to find her candidate. Becoming a mother could well allow her to save the fate of her twin brother Elios, who is among those selected for the tournament. His goal? To survive at all costs and capture Adona in order to put pressure on her mother and overturn this unjust system. For everyone involved, the battle is just beginning, and the revolution is underway!
