He is seen to be short statured, with hair that is colored a muted blonde and eyes that are colored a light red. In his human-like form, he is dressed in a smart suit, a common uniform worn by all of Bishamonten's shinki.
Kazuha is portrayed as being curious and loyal. This is evident when, after Yukine becomes a Blessed Regalia, he and Karuha ask Yukine if there's any secret to becoming one.
Like his twin sister Karuha, he transforms into a handgun. His gun form appears to be a Colt M1911 semi-automatic.
- Kazuha is voiced in Japanese by the same voice actress as Karuha.
