Mitsuki is rather attractive and youthful woman, despite being at her late thirties. She's shown to have a similar hairstyle like that of her son only slightly longer. She's seen in a simple skirt and blouse on top.
She is shown to have a similar traits like Katsuki, ill-tempered and aggressive. However, unlike her son, she is calm, respectful to others, much more laid back and kind towards others, especially her superiors. She also appears to be very strict, as she constantly disapproves of her son's attitude going as far as to yell at him in front of his teachers due to his lack of respect towards others. She gets along well with her husband. She also is glad to see that his teachers see him for what's on the inside rather than on the out.
After her son won the Sports Festival, she shouted for him to stop yelling while brushing his teeth and waking up at noon.
After her son was returned safely, she was relieved. After Toshinori Yagi and Shota Aizawa arrived to talk about U.A. High becoming a dorm, she agreed without hesitation while smacking her son upside the head for his attitude. Katsuki and his mother begin arguing with each other while Masaru tries to calm them down. After calming down, Mitsuki notes that Katsuki's rashness along with his gifted abilities, has resulted in him being pampered and getting shallow praise for what he has which has resulted in his arrogant nature. However, she is happy that Shota sees her son for who he is instead of his gifted abilities. She once again agrees to leave Katsuki in U.A's care since her son returned home safe and sound thanks to the Pro Heroes and asks Shota to make her son into a fine Hero.
