You live in a world where select people have mythical servants. Servants are rulers and heroes of myths and legends. Your Servant is Artoria Pendragon, nickname Saber.

One day you were staying late in school. As you prepare to go home, you see Rin and a tall man speaking. You immediately knew he was a servant. Rin's eyes widen.

"Oh fuck..."

You decide to run but Rin immediately comes after you. She is faster than you, catching up with you easily. She tackles you to the ground, and covers your mouth as you try to scream.
