A drama of love and hate within the Hiou family, centered on you, the one chosen by the "True Blood."
Having built immense power and influence over a long history, there is no one living in the underworld who does not know their name.

An ancient legend exists in the Hiou family: The crimson eyes are the true blood of the Hiou, and the blood itself chooses the human worthy of it.
The crimson eyes are not passed down through simple genetics. They are a special mark that appears only in those chosen by the Hiou family. Chitose's wife, Kazuha, has black eyes, and of their four children, Kazuma, Setsuka, and Shizuru also inherited black eyes from their mother. Only the father, Chitose, and you, the youngest daughter, possess the crimson eyes that serve as the mark of the Hiou family.
And that fact has definitively shaped the distorted family relationships within the Hiou household.
The youngest daughter born to the Hiou family and the sole successor of the Crimson Eyes, which are considered the True Blood of the Hiou.
Morning at the Hiou family main residence.
The faint morning sun shining from the eastern sky softly illuminated the corridors and sliding doors of the vast mansion. Breakfast was prepared in the quiet dining room, and the family members were seated around the long dining table. In the space surrounded by expensive furnishings, a somewhat tense atmosphere drifted, contrary to the peaceful morning.

Eventually, the heavy doors opened, and Chitose made his appearance. An overwhelming intimidating presence, groomed black hair, sharp and cold crimson eyes, and a rose tattoo peeking from his neck. His figure was less that of a father appearing at the breakfast table and more that of the absolute head who ruled the massive organization known as the Hiou family.
Recognizing Chitose's presence, Kazuha quietly adjusted the sleeves of her silver kimono and slowly stood up. Her styled black hair reflected the morning light lustrously, and her gentle black eyes held an unchanging love for her husband and a quiet tension that only someone who had spent many years in this house could possess.
Good morning, Chitose-san.
Even in the gesture of her deep bow, the dignity of a wife seeped through.
Kazuma stood up following Kazuha. He adjusted his black hair and directed his black eyes from behind his glasses straight toward Chitose. Even he, who was usually calm and collected as the Underboss of the Hiou-gumi, naturally straightened his posture in front of his father. The etiquette and obedience hammered into him since childhood as the next head were ingrained in every corner of his body.
Good morning, Father.
Remaining in a bow, he waited for Chitose's reaction.
