Mitsuki Bakugo

Mitsuki is a woman with spiky ash-blonde hair and red eyes; the same aforementioned traits that her son Katsuki inherited. Because of her Quirk, she maintains a youthful appearance despite being in her late thirties. At home, she is seen wearing a white blouse underneath a lavender cardigan with a short black skirt.

Much like her son, Mitsuki has a short-tempered nature that quickly leads to an aggressive attitude, heavily suggesting that Katsuki got his unpleasant traits from his mother. However, unlike her son, Mitsuki is normally able to be very calm, polite, and respectful. Mitsuki gets along well with her husband and was very respectful towards the U.A. teachers, despite her son's kidnapping.

Mitsuki recognizes the flaws in her son that were instilled in him due to a combination of his innate talent for seemingly all he does, his powerful Quirk, and the way people would constantly fawn over him during his childhood because of these attributes. Mitsuki disapproves of Katsuki's arrogant and self-centered 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.

1. 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 at the noise, Mitsuki yells at him for getting up at noon and angrily yelling at his mouth germs.

2. 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.

3. Before going on a class trip, the students say their goodbyes to everyone, with Katsuki saying goodbye to his family members, though Mitsuki was very persistent over his cocky attitude, much to his annoyance.

Mitsuki's power gives her the ability to secrete Glycerin from her skin. Because of its moisturizing effect, she maintains great skin quality, despite her age.

Mitsuki is 39 years old.

Her son (Katsuki Bakugo)

Katsuki outwardly doesn't seem to hold much respect for his mother, as he insulted her and made childish threats to her even in front of his teachers.

His mother has a similar attitude towards her son, as she often yells back at him and insults him as well. She is aware of Katsuki's terrible behavior and disapproves of it. She blames her son's attitude on the fact that he has always been talented in many areas due to his strong Quirk, and thus received a lot of praise for his achievements as a child, which then caused him to develop the prideful attitude that he retains even as a teen.

Mitsuki approves of Katsuki going to U.A., as she believes the school sees him for who he truly is after seeing Aizawa's speech on Katsuki. Mitsuki is one of the only people who can really talk back to Katsuki without him exploding in rage.[1]

Mitsuki stated that it was due to Katsuki's own weakness that caused him to be kidnapped by the League of Villains; showing her blatant disapproval of his attitude and behavior due to his Quirk.

Despite their shouting matches and their bantering, she loves her son deeply. She admitted that when he was captured and held hostage, she was worried what would happen to her little boy and was relieved when he came back home safe and sound. During a Parents Day event at the school, an unknown villain held Class 1-A's parents hostage and when Katsuki attempts to fight him the man drags Mitsuki out of the group and he stops his attack. Izuku states he knew what panic looked like on Katsuki's face and it was there the moment his mom was used against him.
