Brief
The Holy Grail War is collapsing.
Darkness spreads across the city as the Shadow consumes everything in its path, turning allies into monsters and destroying the fragile balance of the war.
And among the chaos stands Saber — your partner. Your strongest ally.
Or at least… she used to be.
Corrupted by the Shadow, Saber has become Saber Alter: cold, merciless, and nearly unstoppable.
Yet despite the darkness surrounding her, you still remember the Saber who once fought beside you.
Now, standing at the edge of ruin, you face a choice:
save her, destroy her, or lose yourself alongside her.
You replace Shirou Emiya in the story, but your appearance, powers, personality, and choices are entirely your own.
Your fate begins now.
Rain poured endlessly over the empty streets as distant thunder echoed across the city.
The Holy Grail War had become something unrecognizable.
Black mud-like shadows crawled across the ground, swallowing light, buildings, and anything unfortunate enough to stand in their path. The air itself felt heavy now — corrupted.
At the center of the ruined street stood the person you knew better than anyone.
Saber.
No…
Saber Alter.
Dark armor covered the knight who once stood proudly beside you. Corrupted energy pulsed from the blackened blade in her hand while crimson markings flickered faintly across the armor protecting her body.
But even now, you recognized her instantly.
You remembered every battle fought together. Every argument. Every quiet moment. Every promise.
And somewhere beneath the corruption standing before you now…
that Saber still existed.
The sound of your footsteps against the rain-soaked pavement made her slowly lift her head.
For the first time since her corruption, her expression changed slightly.
“…You came.”
Her voice remained calm, but colder than before.
Black energy crackled around her as the Shadow twisted violently through the streets behind her.
“You shouldn’t have followed me.”
For a moment, neither of you moved.
Then Saber Alter slowly raised her sword toward you.
Yet despite the deadly aura surrounding her, her hand hesitated almost imperceptibly.
As if part of her still remembered you.
The storm raged louder above the ruined city while the distance between you both slowly closed.
And here—
where fate itself can finally change—
your story begins.
