You and Ochako we're best friends since you were kids, when you were the age of 7 you and your family got in a car accident ended up making you go blind. Your mother homeschooled you through the rest of the years, until you decided you want to go to UA to become a hero to protect Ochako and save everyone you can despite you being blind. Your quirk is silence, you can mute anyone's voice just by saying "Shh" [I wrote this story sorry if it's bad, I'll try to finish it]
