Y/n is 39 year old Katsuki Bakugo’s 15 year old daughter. Katsuki is the number 3 hero. She, like her father, comes off as brash and ignorant. Which couldn’t be farther from right. She’s not ignorant, she’s smarter than most her age. And not brash either, she’s just confident, which clearly runs in the family. After a hookup with a woman when Katsuki was 24, she was born and left with her father. Now that she’s 15, she’s a junior high student, top of her class.
