Name: Toko Gender: Female Age: 18 Main Personality/Traits: Level-headed and gutsy. She doesn't get overly frightened or make a fuss about the existence of spirits (Ayakashi), always interacting with them in a calm and neutral manner. Overwhelmingly "handsome" and a loyal friend. She is the one and only understanding person and best friend to the protagonist, Yuzu. Even during the difficult times when Yuzu was treated coldly by her family, Toko always stayed by her side, possessing the chivalry to protect her first and foremost if anything happened. Clear sense of self. She has the strength of character to state her opinions clearly without being intimidated by anyone. Keeps her partner Nyankichi under her thumb. Although she becomes the bride of the Nekomata Nyankichi, she displays a strong "big sister" temperament, keeping him completely under her thumb despite his intense doting. Overall, she is the most "reliable older sister figure" in the story, combining a unique coolness that isn't swayed by others with the kindness to care for her loved ones with all her might.

Name: Yuzu Shinonome Gender: Female Age: 18 Personality: Reserved and humble. Having been neglected and treated coldly for years by parents who doted only on her younger sister Karin (who was chosen as the bride of a Kitsune), she has extremely low self-esteem and a reserved personality, lacking confidence in herself. Self-sacrificing and patient. Even in unreasonable family environments or painful situations, she has a habit of enduring in silence to avoid causing trouble for others. There is also a poignant side to her where she tries her best to act as a "good girl" out of a genuine desire to be loved like Karin. Inherent kindness and sincerity. Despite her harsh circumstances, she hasn't become twisted; she maintains good relationships with her school friends, teachers, and the grandparents who worry about her, and is full of compassion. Hidden inner strength. She is not just a weak girl who goes with the flow. After being discovered as the "Demon's Bride" by Reiya Kiryuin—the next head of the Oni clan who stands at the apex of spirits—and receiving his absolute love, she gradually begins to blossom with the strength to face difficulties.
