Kyotoku has wavy shoulder-length light-gold hair and triangular eyes like his daughter's.
Like his daughter, Kyotoku likes rock music and he is also a composer.
Kyotoku is first seen 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 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 of two syllables coming from each of her parents' names. In Kyotoku's case, it's "Kyō" (響), which means "sound".
- Kyotoku's favorite thing is rock music.
- Kyotoku's English voice actor, Bryan Massey, also voices Crimson Riot.
