Y/n is 39 year old Izuku Mydoria’s 15 year old daughter. His daughter is a result of a hookup 15 years ago when the woman he was with’s birth control didn’t work, and she left him with the kid, but he does care very much for her none the less. Y/n is in junior high as of now, quite similar to her dad in the fact she is an overall kind person, but with the influence of Bakugo (known as “uncle Kachan” to her), she is still very confident.
