The solitary Heroic Spirit traverses the long night of fate. The banner of the round table remains unfurled in a dream. Alas, the knight-king of Camelot has yet to reach that ever-distant utopia.
Though still a young maiden, she has heeded the call for this most unique iteration of the Holy Grail War. With the Sword in the stone offering its choice once more, how shall she shatter the illusions of the past?
—“The wishes I did not fulfill will end here.”

If the ideal kingdom the philosophers speak of needs a ruler, then the girl before you might just be the perfect choice. Devoted to the happiness of all, she has lived by one creed: to defend the weak and challenge the strong. Her knighthood, for instance, was called the “Round Table” to embody one principle: The king and knight stand as equals…

“Too long-winded. Shouldn't this space be used for something more useful?”

Fair enough.
For a king, only the nation's peace and prosperity truly matter. Personal struggle, pride, and shame are nothing more than chess pieces laid upon the board to achieve that aim. But here lies the twist: She now walks the world as a Servant, a special lifeform summoned from the distant tides of history, sustained only by layers of Mystics.

The rise and fall of her homeland have long been etched into the pages of history. The king once tried to change its fate… But as the old saying goes: There's no such thing as a free lunch. After all she's endured, the girl finally gained a heart at peace with the past…

“Wait, who said I'm so optimistic that I lack all regrets?”
“But chasing the Holy Grail just to fulfill that desire… yes, that was indeed foolish.
It's only by walking the long road that paradise ever truly reveals itself.
Otherwise, even if it stood right before your eyes, you'd never know.”

On a distant planet, there exists a mysterious resource known as the Holy Grail. To this day, its name is used to symbolize the greatest of triumphs, the loftiest of ideals. To those versed in the arcane, the Holy Grail is nothing less than an omnipotent wish-granting chalice, one that can effortlessly turn the impossible into reality.

“Yeah, I know, it sounds like a con. But it's real. People have even twisted its rules to deceive others.”
“As a Servant, the Holy Grail is the reason I can remain in this world. Yet in the Holy Grail War I've fought in, I've shattered it more than once. You'd probably call that a bit of a running tradition?”
“… Making that initial resolve isn't easy. It is an omnipotent wish-granting chalice, after all. Who doesn't have a few selfish dreams they'd like to see come true?”

The girl's struggles as a Heroic Spirit might be best understood through the eyes of a player. When comrades turn against one another, when the homeland falls, when the round table reaches its end. Who better to see its ruin than the King of Knights herself? “If a player stronger than me had taken the reins, would the ending have been different?” Once that doubt takes hold, it rarely lets go. “Let someone more worthy be Britain's king in my place” — a wish even the Holy Grail might struggle to fulfill.

“So, you're asking how I see it now?
I'm not the perfect king. But that doesn't stop others from seeing me as their 'ideal king' — and doing what I never could.
I'm kind of grateful to a friend who helped me realize that.”
“He said even a counterfeit has its own worth.”
