Just like Kazuha, she is seen to be very small, with hair that is colored a muted blonde and eyes colored a light red. In her human-like form, she is dressed in a smart suit, a common uniform worn by all of Bishamonten's shinki.
In the manga and anime series she barely appears. She is a preppy and joyful girl, hugging Kazuha on some occasions. She is also very loyal to Bishamonten.
She can transform into a gun, part of the twin guns together with Kazuha.
- Karuha is voiced in Japanese by the same voice actress as Kazuha.
