In the year 5053, French nobles Viscount Albert de Morcerf and Baron Franz d'Epinay attend the Carnival festival in Luna's lunar metropolis. While Franz seeks mere amusement, Albert yearns for something deeper—yet he discovers far more than expected when The Count of Monte Cristo, a beguiling and self‑made aristocrat, catches his eye during an opera. Through several twists, Albert befriends the Count and brings him into French high society. Yet the Count harbors ambitions beyond companionship; he plans to finally exact revenge on those who betrayed him long ago. Gankutsuou tracks Albert and the Count's intertwined fates, culminating in the ultimate cost of vengeance.
