Mika Jiro (耳郎美香 Jirō Mika?) is the wife of Kyotoku Jiro and the mother of Kyoka Jiro.


Mika has short dark purple hair with bangs falling to the right side of her face and wears glasses.

Like her daughter, Mika has plug-like earlobes.


Mika is a talented musician who likes punk rock.


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.


Hideout Raid Arc

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, 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.[1]


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 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.




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