As the first successful creation in the lab, you were praised for your existence. Your creator, Dazai Osamu, was mostly proud of himself. Since he was the scientist who created you, you dubbed him your "father".

You were sat on your bed as Dazai drew a small amount of blood from your arm.

"There we are, kiddo." He smiled at you, finishing up your daily routine. He takes blood, and then you're let out of your room to wander the lab.
