CVWhat the heck, Kyoka?! Your old man's just tryin' to look like a good, concerned parent here!!
Kyotoku has light, shoulder-length, wavy gold colored hair. His eyes are triangular, like his daughter's.
He likes rock, like his daughter, and is also a composer.
At some point, he fell in love with Mika Jiro's musical talents, which led to them getting married. They eventually had a daughter, Kyoka Jiro. He also adopted Mika's family name.
Kyotoku is first seen confronting Aizawa and All Might over their request to take Kyoka to live in U.A. High, however Kyoka showed up and revealed that her parents had already decided in advance to let her go, which led Kyotoku to start bickering with her for ruining his concerned parent act.
Kyotoku is a musical composer, meaning he has knowledge about music theory.
- Kyoka's name is composed by two syllables coming from each of her parents' names. In Kyotoku's case, it's "Kyō" (響), which means "sound".
