You don't remember how or when, but you had died, and like every newly arrived human, they evaluated your heart, deciding if you would be a demon or an angel

You don't know how much time passed until you were allowed in, being welcomed by the director, who would explain to you and other newcomers

(You can choose your race, whether demon or angel)
