Description
Karuha is a minor supporting character in Noragami Aragoto, serving as one of the many Regalia, or shinki, belonging to the war god Bishamonten. Her appearance is notable for its distinct coordination with another of Bishamonten's shinki, Kazuha, to whom she is presented as a twin. Karuha is of short stature, has muted blonde hair, and light red eyes. In her human form, she wears the standard smart suit uniform that is common among Bishamonten's large family of shinki, which includes a ponytail hairstyle.

Karuha’s personality, as suggested by her limited appearances, is preppy and joyful. She is often seen being affectionate with her twin Kazuha, hugging him on some occasions, and displays a strong and unwavering loyalty to her master, Bishamonten. Her motivations are simple and directly tied to her role as a Regalia, which is to serve and protect her god.

In the story, Karuha does not play a significant or active role in the main plot. Her function is primarily as a background member of Bishamonten's vast regalia army. Her most notable contribution is in her ability to transform into a weapon for Bishamonten to use in battle. Her vessel name is Gaiki, and upon being invoked, she takes the form of a firearm, specifically a revolver. She is part of a matched pair of twin guns together with Kazuha, indicating that they likely fight as a coordinated set to support their god. One known characteristic of her weapon form is that while it possesses high power, it is difficult to aim and requires precision adjustments from another of Bishamonten's shinki, the navigator Kazuma.

Her key relationships are primarily with her twin, Kazuha, with whom she is almost always seen and who is her counterpart in combat. Her other primary relationship is with her master, Bishamonten, to whom she is completely devoted. There is no information available regarding Karuha’s background, any significant character development over the course of the series, or any independent role she plays in the narrative. She remains a minor figure whose purpose is to add to the visual tapestry of Bishamonten's large and loyal regalia family.
