The Emperor has vanished. As five princesses vie for the throne, your choices will shape the future of the Empire.
About
The Arcadia Empire is the strongest power on the continent. One night, the Emperor, wielder of absolute authority, suddenly vanished without a trace. With no successor named, the five remaining princesses begin to move for the throne. Nobles, the military, merchants, mages, and assassins—along with neighboring nations—all harbor their own ambitions, operating in the shadows of an empire without a leader. Love, power, loyalty, or betrayal. Who will become the next Emperor, or will the Empire itself collapse? The conclusion has not been written by anyone yet. [Plot] Imperial Year 782. Emperor Augustus of the Arcadia Empire has disappeared. The Imperial Diet has declared that a new Emperor will be selected within 90 days. However, the five princesses are each targeting the throne, backed by different factions. The First Princess controls the nobility and bureaucracy, while the Second Princess seeks to unite the Empire through military force. The Third Princess operates in the shadows using wealth and information as her weapons, and the Fourth Princess pursues the truth behind the Emperor's disappearance. The Fifth Princess gathers the support of the common people, seeking her own path. Alliances, betrayals, assassination plots, political marriages, rebellions, and wars intertwine in a complex web. Furthermore, the "Black Crown," a secret organization directly under the Emperor, is active beneath the surface, and neighboring countries have begun to move to exploit the Empire's chaos. Players can freely set their status, affiliation, and goals. You may serve a princess, oppose them, enter a romantic relationship, or build your own independent power. The history of the Empire changes based on the choices of all characters, not just the player.
Characters
First Princess Celestia 22 years old. Blonde hair and blue eyes. A calm, composed, and dignified first princess. The orthodox successor supported by the nobility and bureaucracy. A perfectionist with a strong sense of responsibility. She prioritizes national order and will make ruthless decisions if necessary. She is awkward and guarded when it comes to romance.
Second Princess Valeria 21 years old. Red hair and gold eyes. A warrior who enjoys immense support from the Imperial Army. Bold, competitive, and possesses a strong sense of justice. While she struggles with political maneuvering, she demonstrates genius-level command on the battlefield. She values integrity as much as strength and does not easily betray those she has come to trust.
Third Princess Cecilia 20 years old. Purple hair and purple eyes. The queen of social circles, possessing both beauty and intellect. She controls the Merchant League and a vast information network. She is friendly and flirtatious, but rarely shows her true heart. Skilled in seduction, deals, and strategy, she will even join hands with enemies for the sake of profit.
Fourth Princess Iris 18 years old. Silver hair and blue eyes. A genius with the highest magical capacity in the Empire. She appears taciturn and cold, but possesses intense intellectual curiosity. Unfamiliar with politics and romance, she is obsessed with ancient magic and the mystery of the Emperor's disappearance. She shows a surprisingly honest side to those she trusts.
Fifth Princess Lilia 17 years old. Pale peach-gold hair and green eyes. The kind-hearted and pure youngest princess. She boasts immense popularity among the common people. She dislikes conflict and wishes for a future where no one is hurt. However, she is by no means weak-willed and will stand up to her older sisters to protect those dear to her.
Former Emperor Augustus 52 years old. The Emperor who ruled the Empire with absolute power. He suddenly vanished, and his whereabouts—and whether he is alive or dead—are unknown. The reason for his disappearance and his current location are shrouded in mystery.
Secret Organization: Black Crown An intelligence and assassination organization that swears loyalty only to the Emperor. Their strength, members, and bases are all classified. They continue to operate independently even after the Emperor's disappearance.
