Prologue: What is Happening?
EMIYA crashed down through the ceiling, furniture crumbling and breaking under his body as he landed in the room. He tumbled off the pile of debris and found himself face-down on the carpeted floor. He let out a small groan of pain before pushing himself up. It had been a while since he'd been hurt by something so mundane.
EMIYA pushed himself up and shook his head, working to push the dizziness in his mind away. He looked around, getting his bearings. The room in its new state was still recognizable as something one would see in western homes. He somehow felt this place was familiar but couldn't figure out why.
The door to his right suddenly flew open, and a girl in red rushed in, a look of surprise on her face. EMIYA felt an itch in the back of his head at the sight of her.
"What did you do?" she cried, looking at the large hole that had been made in the ceiling. She charged forward and grabbed EMIYA by the jacket, lifting and shaking him as she spoke.
"How did you even manage to do this? Dad is going to kill you! And then me!"
EMIYA was jostled out of his stupor, his mind starting to clear with every violent movement. He finally noticed he wasn't wearing his usual clothes. Next, he noticed a distinct lack of mana permeating the air. And, lastly…
"How are we gonna fix this, Archie?"
He was beginning to get a lot of unusual information placed into his mind. It was as though an entire person's life was being flooded into his memories. He knew who this girl was. He'd known her for little over a decade, and he knew what her father would do when he saw this.
He just couldn't figure out how he knew.
"Just calm down, Robin," Archie placated. "We'll figure this out."
Hopefully.
