The Rift

Shirou Emiya stood amidst the ruins of Fuyuki City, the aftermath of the Holy Grail War still fresh in his mind. The air was thick with the scent of ash and the faint hum of residual magical energy. He had done it. After years of struggle, pain, and sacrifice, he had achieved the impossible—the First True Magic, -Denial of Nothingness-. With Alaya's permission, he had transcended the limits of human understanding, gaining the ability to create anything from nothing.

But as he flexed his newfound power, the world around him began to distort. The sky cracked like glass, and a swirling vortex of energy erupted from the ground. Alaya's voice echoed in his mind, cold and distant.

"You have surpassed humanity's limits, Shirou Emiya. But such power comes at a cost. The multiverse is unstable. You must bear the consequences."

Before Shirou could respond, the vortex swallowed him whole, dragging him into the void between realities.

[The Path to the First True Magic]

As Shirou was pulled into the vortex, his mind was flooded with memories of the events that led to this moment. He saw himself standing in the Einzbern Castle, facing Saber and Rin. The Holy Grail War had reached its climax, and Shirou had been forced to confront the darker aspects of his ideals.

"You can't save everyone, Shirou,"- Saber had said, her voice filled with sorrow. "Sometimes, you have to make sacrifices."

"I know,"- Shirou had replied, his voice steady. "But that doesn't mean I'll stop trying."

He remembered the moment he had made the pact with Alaya, the collective will of humanity. Alaya had offered him the power to achieve his ideals, but at a cost—his connection to the world he knew.

"If you accept this power, you will become a guardian of humanity,"- Alaya had said. "But you will no longer belong to this world."

Shirou had accepted without hesitation. He had always been willing to sacrifice himself for the sake of others. But now, as he was dragged through the void, he couldn't help but wonder if he had made the right choice.

Shirou's mind drifted to the final battle of the Holy Grail War. He had faced Gilgamesh, the King of Heroes, in a desperate struggle to protect the world. The battle had been fierce, and Shirou had been pushed to his limits.

"You are nothing but a faker,"- Gilgamesh had sneered, summoning countless weapons from his Gate of Babylon. "You will never surpass me."

But Shirou had refused to back down. He had unleashed his -Unlimited Blade Works-, projecting countless weapons of his own. The two had clashed in a storm of steel and fire, each determined to emerge victorious.

In the end, Shirou had prevailed, but the cost had been high. The Holy Grail had been destroyed, and the world had been saved. But Shirou had been left with a hollow feeling, as if something was missing.

[The Pact with Alaya]

As Shirou drifted through the void, he remembered the moment he had made the pact with Alaya. He had been standing in the ruins of Fuyuki City, the weight of his choices pressing down on him.

"You have proven your worth, Shirou Emiya,"-Alaya had said. "But your journey is not over. The multiverse is vast, and there are many threats that must be dealt with."

Shirou had accepted the pact, knowing that it would mean leaving behind everything he had ever known. But he had been willing to make that sacrifice, for the sake of the world.

As Shirou was pulled through the void, he felt a sense of disorientation. The world around him was a chaotic swirl of colors and shapes, and he could feel the fabric of reality tearing apart.

"Where am I?"- he thought, struggling to maintain his focus. "What is happening?"

Alaya's voice echoed in his mind once more. "You have been cast adrift in the gap between multiverses, Shirou Emiya. You must find your way back, or else you will be forever lost"

Shirou clenched his fists, determination burning in his eyes. - "I won't give up. I'll find a way back, no matter what it takes."

[Location: Gotham City]

Shirou awoke in an alleyway, the cold rain soaking through his clothes. The air was thick with the stench of garbage and the distant wail of sirens. He groaned, pushing himself to his feet. His body ached, and his magical energy was dangerously low.

"Where... am I?"- he muttered, looking around. The city was unlike anything he had ever seen—towering skyscrapers, neon lights, and a pervasive sense of darkness.

Before he could gather his bearings, a group of thugs approached, their eyes gleaming with malice.

"Well, well, what do we have here? A lost little lamb?"- One of them sneered, brandishing a knife.

Shirou sighed, summoning a simple blade with a flick of his wrist. The thugs froze, their bravado evaporating as they realized they had picked the wrong target.

"I don't have time for this,"- Shirou said, disarming them with ease. Before he could question them, a shadow descended from above.

"That's enough," - A deep, gravelly voice said. Shirou turned to see a figure clad in black, his cape billowing in the wind. It was Batman.

"Who are you?"- Batman demanded, his eyes narrowing.

"Shirou Emiya,"- Shirou replied, lowering his blade. "I... don't suppose you know where I am?"

Batman studied him for a moment before nodding. "Gotham City. Follow me. We need to talk."
