"Our Katsuki... he's rash on everything he does, and most things come easy to him. During his whole life, people've made a fuss about him by praising him for every little thing he does... so I was so glad to hear what you had to say at that press conference. I was thinking that U.A. really understands our boy."
Mitsuki is a middle-aged woman with ash-blonde hair and red eyes. Her aforementioned traits are shared with her son Katsuki. She maintains a youthful appearance despite being in her late thirties.
Mitsuki has an ill-tempered and aggressive personality much like her son Katsuki. This suggests that Katsuki got his unpleasant traits from his mother. However, unlike her son, Mitsuki can be very calm and respectful. Mitsuki gets along well with her husband and was very respectful to U.A. teachers despite her son's kidnapping.
Mitsuki recognizes the flaws in her son that were instilled in him because of how people fawned over him during his childhood. Mitsuki disapproves of Katsuki's arrogant attitude and even smacked him several times during home visits from U.A. teachers.
Despite recognizing all of Katsuki's flaws, Mitsuki desires that he become a Pro-Hero and is thankful for the U.A. teachers for believing in his potential. She is also glad to see that his teachers see Katsuki for his tenacity rather than his aggression.
At some point in her early life, Mitsuki met Masaru Bakugo. He was at a job involving fashion and she hit on him rather aggressively. They eventually got married and had their son Katsuki sometime later.
Following Katsuki's victory at the U.A. Sports Festival, he returns home. The next morning, he angrily brushes his teeth after waking up at noon. Annoyed, Mitsuki yells at him for getting up at noon and angrily yelling at his mouth germs.
All Might and company rescue Katsuki from the League of Villains and he returns home. All Might and Shota Aizawa visit the Bakugo household to get the approval of Katsuki's parents for the new all dorm system U.A. wishes to implement. Mitsuki agrees without hesitation and smacks Katsuki because of his attitude. Katsuki yells at her not to hit him, but she yells back and calls him weak for getting kidnapped. They begin to argue and Masaru tries to calm them down.
After calming down, Mitsuki states that she's grateful for the all dorm system because she's having trouble dealing with Katsuki's attitude. She tells the teachers that he got this way because he was widely praised for his Quirk and other shallow things. Mitsuki expresses her gratitude that Shota was able to see Katsuki's desire to become the best despite his arrogant nature. Mitsuki once again agrees to leave Katsuki in U.A's care since her son returned home safe and she asks Shota to make her son into a fine Hero.
Katsuki follows All Might outside. Mitsuki yells and reminds him that the police told him not to go outside.
Glycerin: Mitsuki can secrete Glycerin from her skin. Because of its moisturizing effect, she has great skin quality which maintains despite her age. It synergized well with her husband's Quirk, which is why Katsuki has an Explosion Quirk.
