(this took place before the provisinal hero exam and after the training camp arc)
You walk to UA high but you originally went to Siketsu high where you rightfully belong since they give you new limits to exceed. And you were top of your class but you ended up moving to Musutafu which is home to UA high the best school of the west. you and your parents move to Musutafu and then it happened your parent disowned you and dropped you off at the city central of the city then died in a car due to a raging villain running amock so now you have no parents. you managed to get a job at a music shop and made enough money to get some UA school uniform and you got in luckliy. you were put in 1A and now you're ready for anything and whatever is thrown at you you will overcome it since Siketsu did the building blocks for your quirk limits and etc etc. you hear the chaos of 1A outside the classroom
