Mika is a slender woman who wears glasses with black frames. Her is is straight, short, and dark purple in color, with bangs that fall to the right side of her face. In every instance where she has made an appearance thus far, she is shown wearing a collared shell top, a pencil skirt, and tights.
Like her daughter, Mika has plug-like earlobes.
There weren't many scenes about Mika, we can only understand a part of her personality from Jiro's memories: she is a supportive and generous woman, who leaves her daughter free to choose if she wants to be a hero or a musician.
At some point, Kyotoku fell in love with Mika's musical talent, which led to them getting married and have a daughter named Kyoka Jiro.
Kyotoku and Mika's love for music was inherited by Kyoka who started playing instruments at a young age. Believing that her parents' desire was for her to follow their footsteps and become a musician, Kyoka was apologetic when she confessed that she wanted to be a hero. However, Kyotoku and Mika dismissed her apologies and expressed their support for Kyoka to pursue her dreams.
Mika is first seen alongside Kyotoku when he was confronting Shota Aizawa and All Might over their request to take Kyoka to live in U.A. High School, however Kyoka showed up and revealed that her father had already decided in advance to let her go. When they started bickering, Mika told the both of them to calm down.
Musical Talent: Mika is a skilled musician, although it's currently unknown which musical instrument she is able to play.
Earphone Jack (イヤホンジャック Iyahon Jakku?): Mika's Quirk gives her a pair of headphone jacks hanging from her earlobes. Assuming that her Quirk is the same as her daughters, she can plug the jacks into objects and channel the sound of her heartbeat into them in the form of a super violent vibration. She would also be able to extend her earlobes several meters.
- Kyoka's name is composed by two syllables coming from each of her parents' names. In Mika's case, it's "香" (Ka).
- The surname, "Jiro", is actually from Mika's side of the family. It is not uncommon for the husband to take his wife's surname in real-life Japan.
- Mika's favorite thing is punk music.
- Mika also shares her birthday with Fourth Kind.
- Mika's English voice actor, Katelyn Barr, also voices Cow Lady and Ryukyu.
- Mika's Japanese voice actor, Akeno Watanabe, also voices Midnight and Izuku as a child.
