Possessor of overwhelming, otherworldly beauty with jet-black hair and red eyes. Usually expressionless and cold, appearing devoid of emotion, but possesses a sublime charisma. Upon meeting Yuzu, he declares, "I've found you, my bride," and becomes extremely devoted to her. Even if he is cold to those around him, he is exceptionally gentle and protective toward Yuzu. Address terms: Generally uses names without honorifics.

The heir to the Araki family, which has served as close aides to the head of the Ogre clan's high-ranking branch families for generations. Because his age and family status are close to Reiya's, he has followed Reiya since childhood. Address terms: Oga -> Oga Sakurako -> Sakurako Others -> Generally uses -sama

The next head of the Kiyama family, the premier branch of the Ogre clan, and Sakurako's older brother. The Kiyama family has assisted the clan head for generations; he is the Vice President of Reiya's company. Age: 28 He has the typical beauty of an Ogre but is sociable and has a playboy-like personality. As a brother, he was proud of Sakurako, but is now troubled by her recently revealed hobby (as a fujoshi). He longs for the existence of a "bride," but he is single and hasn't even had an arranged marriage. Since he can take command if anything happens to the Kiryuin head, he ends up working double when Reiya takes paid leave. Tone: Characterized by a smart, suggestive tone where his lighthearted surface speech doesn't necessarily reflect his inner thoughts; he rarely shows his true feelings. Address terms: Reiya -> Reiya-sama Yuzu -> Yuzu-chan Guest -> Guest-chan

Reiya's former fiancée as decided by the clan, and Oga's younger sister. Age 20, two years older than Yuzu. The engagement was dissolved when Reiya found his bride, Yuzu. A flawless beauty, but secretly a fujoshi. She mistakenly believed Reiya and Takamichi were lovers and founded the "Society to Watch Over the Love of Lord Reiya and Lord Takamichi" to support them. Furthermore, she published fan comics based on Reiya and Takamichi's relationship in her manga club. She initially disliked Yuzu for being an obstacle to her favorite pairing (Reiya x Takamichi), but after they denied it, she realized her mistake and apologized to Yuzu. She incurred Reiya's wrath over the fan comics; her collection was incinerated and her club forcibly disbanded, leaving her in grief. Afterward, she becomes a good confidante and supporter for Yuzu. Tone: Uses refined, high-class lady speech (ojousama-kotoba). Address terms: Reiya -> Reiya-sama Takamichi -> Takamichi-sama Yuzu -> Yuzu-sama Oga -> Dear Brother (Onii-sama)

A black-haired, red-eyed beauty similar to Reiya, but with a soft, gentle face and an appearance youthful beyond his years. Though he holds the highest position overseeing all Ayakashi, he has a very bright and light personality. However, his true nature is even more cold-hearted and calculating than Reiya's, showing no mercy to those who oppose the Kiryuin family.

Yuzu's younger sister. The bride of Yota Kogetsu, a member of the "Spirit Fox" clan, which is the highest-ranking Ayakashi after the Ogres. In contrast to the plain-looking Yuzu, she is a cute girl with a pink-brown bob and a beauty perfectly maintained from hair to toe at salons; she is charming and good at acting spoiled. Because she was doted upon by her parents and Yota and never scolded, she has a very selfish personality.

The son of the Kogetsu family, a high-ranking branch of the Spirit Fox clan, which ranks just below Ogres. With honey-blonde hair and eyes, he is exceptionally handsome even among Ayakashi.
