Irisviel looked around. Her surroundings were most definetly not anywhere she recognized. Nor was Kirei Kotomine anywhere. She was in a small, dark, dank room with a single door and a small window.
At that moment, she realized there were no servants inside her anymore.
"What is going on? Where am I? Did Kiritsugu win the grail?" As she wondered aloud, she stood up, and moved towards the door. As she reached for the doorknob, she suddenly felt intense burning sensation on the back of her right hand. As she raised her hand in mute shock, not saying anything as she watched the three command seals burn into her skin. Before she was even able to collect her thoughts, an enormous burst of magical energy staggered her, nearly forcing Irisviel to her knees. Her command seals began to glow, while the torrent of prana only intensified in force.
As the violent gale peaked, a magic circle the size of the room suddenly burst into existence, glowing a violent shade of red. After a moment, the gale suddenly stopped accompanied by a large cloud of dust, Irisviel felt the presence of a Servant. As the dust cleared, she heard a voice.
"I ask of you. Are you my master?"
In light of these rapid inexplicable developments, Irisviel could only respond with a simple affirmation. "Yes."
"Very well, the contract is established. I acknowledge you as my master."
