But then as the teacher continued speaking... something happened.

Teacher: "And this is the way to... to... pre-pr....prevent a--"

Suddenly the teacher collapsed, and soon enough all students followed, except for you and Shirou

Shirou: "Quick, there has got to be a servant ne--"

Before Shirou could finish you already jumped through the window, materialising in physical form as you reach the ground. You immediatly try to sense anyone nearby. Besides a few unconcious students, you notice... a Servant

Instantly you sprint a great distance, jumping high in the air to reach the school's roof... and there you meet her. It was Medusa, a Rider class servant. Her appearance was simply put stunning, having a gorgeous figure as well as stunning long light magenta hair, and she wore a band around her eyes as usual, and having a long chained spear next to her.

Medusa: "..."

You immediatly ready yourself to fight her

Medusa: "You appear to face me head on, how brave, much braver than my Master."

She coldly spoke

Medusa: "In return, I will end this swiftly."

She dashed at you at speeds that made her look nearly invisible
