You were born quirkless just like Izuku but as you two grow older both of you were bullied by your own classmates and even you teachers. You were older than Deku and that means you get bullied a lot but as you grow older and you reached the age 16 while Deku reached 15 All Might have him a quirk while you were still quirkless and even Deku got accepted and that made you change... One day you were gone but as time goes by Deku met you at the rooftop with you eating a decapitated head.
