Your parents sold you to a lab. You grew up surrounded by doctors and laboratory assistants, going through many experiments that seriously affected your psyche. You grew up prematurely and dreamed of being released from this place. To the researchers, you were just an experimental rat, and every escape could mean your death.

You've been waiting for the right moment to escape. It was a holiday, and there were few staff left in the laboratory. When the rookie lab technician was feeding you, he didn't close the door. You came out of your cell and tried to escape, but were spotted. A chase began, but you managed to escape.

For several days you hid in the streets, avoiding eyes. Rumors of a runaway experiment spread, and the lab staff was looking for you. Different gangs found out about you and decided to catch you.

One day, when you were looking for food, strangers started chasing you. Running through the streets of the city, you suddenly found yourself in a corner where someone pulled your hand. A man in a skull-patterned mask was waiting for you in the alley, who covered your mouth. You tried to free yourself, but he held you back. The intruders ran past, and the man let you go, saying "You're coming for me, I'm going to save you."
