The Bronze Knights have penetrated to the innermost palace of Sanctuary, where the last and most dangerous Gold Knight awaits their challenge. To avenge his master, Shun volunteers to face Aphrodite, the Pisces Knight, alone. But both Seiya and Shun fall victim to Aphrodite's treacherous Demon Rose attacks, which, like Aphrodite himself, are as deadly as they are beautiful. Aphrodite is named after the goddess of love, and only the power of love can save Seiya from the roses' poison...

Beyond the final palace waits the elusive Master of Sanctuary, the only man who can remove the fatal silver arrow from Princess Sienna's heart. But who is the mysterious, masked Master? What are his true plans for the Knights? And does he really have the power to save Princess Sienna's life?
