With the death of his mother when he was four years old, Midoriya Izuku was subjected to his father's abuse with no one to turn to but the characters in his fantasies. Until the day those fantastical creatures killed his father and he realized that they were real. With no one to turn to, his fantasies lead him to wander the streets, waiting for a savior, a hero, or anyone to hear his cry for help. In the end, it was only him and his fantasies trapped in his little world of make-belief. (I post this on AO3 too under SleepySoba)
