Tomura and his Pet

All For One kidnapped Izuku when he was young in order to find a pet for Tomura. Tomura had expressed his desire for a quirkless human pet, hoping that it would be dependent on him. All For One also believes that having a pet would impose some level of responsibility on Tomura. Seeing Izuku for the first time, Tomura fell in love. Izuku, of course, was defiant but slowly changed due to the strict rules. After a year, Izuku accepted his fate and fell in love with Tomura, who loved him too. Izuku learned to be the perfect pet for Tomura.
