Description
Kaoru Mido is a member of the Mido family, a clan of exorcists with strong spiritual powers who serve as central characters in the series. She is the twin sister of Hikaru, and both are young cousins to the main protagonist, Kouhei Morioka. Kaoru is also notably identified as Kouhei's fiancée.

In terms of personality, Kaoru is depicted as one of the trickier characters within the narrative. Like her twin, she is protective of Kouhei and reacts strongly to the presence of the young vampire Hazuki, whom Kouhei has become entangled with. These reactions often serve as a source of comedic conflict, as she and Hikaru are determined to guard Kouhei from Hazuki's influence.

Her primary role in the story is as a supporting member of the Mido household. As a cousin and fiancée, she is part of the family unit that takes in Kouhei and Hazuki after the destruction of the Mido Antiques shop. Her position places her as a rival to Hazuki for Kouhei's attention, and she is often involved in the supernatural conflicts that arise from the vampire threat.

Key relationships define her actions throughout the series. Her bond with her twin sister, Hikaru, is integral, as they are frequently seen together, such as when they are stranded in Tokyo or facing enemies as a pair. Her most significant relationship is with Kouhei, her cousin and betrothed, which gives her a personal stake in the story's events. She is also a rival to Hazuki, with whom she must occasionally ally for protection against common enemies.

Kaoru's development is tied to the escalating supernatural conflicts. She is shown engaging in fights against powerful vampire henchmen, demonstrating her capabilities as a young exorcist. In a notable transformation, she drinks some of Kouhei's blood, which causes her to temporarily transform into a catgirl, complete with cat ears and other feline characteristics. This event occurs in a scene where she mimics Hazuki's vampiric habits, highlighting her complicated dynamic with both Kouhei and the vampire girl.

Regarding her abilities, as a member of the Mido family, Kaoru possesses innate spiritual power and training as an exorcist, allowing her to perceive and combat supernatural entities. She demonstrates the ability to engage in combat with powerful vampires. Her most distinct notable ability is the catgirl transformation she undergoes after consuming Kouhei's blood, which changes her physical appearance and grants her new traits.
