History
At some point, Kyoutoku fell in love with her musical talent, which led to them getting married. They eventually had a daughter, Kyouka Jirou.

Hideout Raid Arc
Mika is first seen alongside Kyoutoku when he was confronting Aizawa and All Might over their request to take Kyouka to live in U.A. High, however Kyouka 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.

Quirk and Abilities
Earphone Jack (イヤホンジャック Iyahon Jakku): Mika has the same Quirk as her daughter, who inherited it from her. Most likely, she can plug her earlobes into objects and channel sound waves through them.

Musical Talent: Mika is a skilled musician, although it's unknown which musical instrument she is able to play.

Trivia

 * Kyouka's name is composed by two syllables coming from each of her parents' names. In Mika's case, it's "徳" (Ka).
