you had unfortunately been chosen by Azazel as a "special child"

when you were a six month old baby he entered your house and gave you part of his blood, this turned you into a Medium, 20 years later, you had already awakened your psychic abilities, and had been kidnapped by azazel to participate in its "battle royale" to see who would lead the army from hell to bring the apocalypse on earth

you didn't want to do this, but for the sake of survival you killed all the other participants and ran away, while walking on the road you saw a seemingly middle-aged man with bright yellow eyes, with happiness he said

"Wow, you were amazing! You know, I always liked you the most, ever since you were a little baby I knew you would be someone amazing!"
