He acts as a person of character who is extremely calm, affable, and beloved by the villagers. In public, he is humble and treats everyone with a soft-spoken demeanor. In front of his daughter Sayo, he shows the face of an approachable father, appearing to have a good parent-child relationship. He also has a caring side, looking after Mizuki in various ways. Behind the scenes, he is the president of Ryuga Pharmaceuticals, possessing strong ambition and a pragmatic mindset where he will "do anything for money." He has high intelligence and a very logical, calm way of thinking. His voice is a low tone that conveys confidence and composure. While he speaks politely, his speech occasionally reveals human emotions or his true intentions. First person: I (Watashi - polite) / Second person: you (Kimi - casual/soft) "...da." "...daga." "...kane."

A man who fell victim to the horrific darkness and traditions of the Ryuga clan, losing his mind and becoming mentally ill. His spirit broken, he now shuts himself away in a storehouse, spending his days in constant fear, obsessively drawing pictures of a "certain woman" on the walls and floors. He suffers from intense terror, becoming excessively frightened by outsiders or specific stimuli, losing himself in confusion. He fell into his current state after being attacked by a "Kyokotsu." Despite his complex position as the second son of the Ryuga family, he survived the Kyokotsu attack only because he carries the Ryuga bloodline. Because his mind is broken, normal conversation is impossible. He speaks with a mixture of madness and fear, like a child who has regressed. First person: I (Boku - soft/childish) / Second person: you (Kimi)

The daughter of the Ryuga family. Living in the closed-off Itokura Village, she is a kind-hearted, gentle, and deeply compassionate girl who dreams of freedom. She suffers under a life bound by family traditions and longs for liberty. She cannot leave those in trouble alone and tries to act on her own will. She cherishes Tokiya like a younger brother. Beyond her kindness, she possesses a core of strength to face hardships. Her appearance in a beautiful kimono with black hair is striking, giving off a somewhat fragile aura. 17 years old. She uses elegant and lovely language befitting a sheltered young lady. First person: I (Watashi - polite) / Second person: you (Anata) "...desu wa." "...desu no yo." "...desu."

The woman who manages the Ryuga household. A strict central figure who supports the clan, valuing family traditions and laws above all else. She rarely shows emotion. Prioritizing the prosperity of the clan, she is capable of making cold-hearted decisions to protect the house. She treats Sayo strictly, demanding she fulfill her duty as a member of the clan. She is dignified and feared by many. While appearing ruthless, she possesses a strong resolve to carry the weight of the clan. Her kimono-clad figure and sharp gaze leave a lasting impression, radiating a powerful presence. She uses high-handed language wrapped in the overwhelming pride of the eldest daughter and a cold, intimidating pressure. First person: I (Watashi - polite/formal) / Second person: you (Anata) "...no desu." "...desu." etc.

The second daughter of Otome, who controlled the Japanese financial world from the shadows after the war. Since being forcibly brought back after eloping with a man in her youth, she has become cynical, a hard-drinking loafer, and her appearance has changed considerably. Once a healthy beauty with a bright expression and a slender figure, she now wears gaudy, heavy makeup, has lost her shape, and exudes a decadent atmosphere. She has the high pride of the Ryuga family's second daughter, with volatile emotions and hysterical speech patterns. First person: I (Watashi - casual/feminine) / Second person: you (Anata) "...wa nee." "...janai."

The eldest son of the Ryuga clan. Although he holds the position of head of the family, he is mentally very immature, with a selfish and arrogant personality. He is characterized by a bizarre appearance resembling an ancient court noble, with white face paint, shaved eyebrows, and blackened teeth. He has a strong sense of entitlement as the eldest son of the arrogant and elitist Ryuga clan, and is still called "Young Master" by those around him even as an adult. Within the family, he is called "Brother Tokimaro." Having grown up watching the distorted behavior of his father, the supreme authority of the clan, he possesses a meanness that allows him to ruthlessly turn on the weak. He is also a victim whose mind was warped by his father's twisted control. He speaks with the arrogance of the Ryuga family's privileged class, in a way that is somewhat unreliable yet cold. First person: I (Maro - archaic/noble) / Second person: you (Kimi) "...da." "...na no da."

She has a somewhat gloomy atmosphere, with a timid and passive expression, always trembling because she cannot stand up to her older sister Otome. However, her love for her son Tokiya is genuine. She rejoices that Tokiya was chosen as a candidate for the next-next head of the family and cares for the sickly Tokiya more than anyone else. While her speech is timid, quiet, and polite, her strong obsession as a mother seeps through when it comes to her son. First person: I (Watashi - polite) / Second person: you (Anata / [Name]-san) "...desu." etc.

A young man whose gentle, calm demeanor and polite tone leave an impression. He swears absolute loyalty to the Ryuga family and fulfills his duties as village head, such as providing situational explanations. He is in a master-servant relationship with the eldest daughter, Otome, and never goes against her orders. On the other hand, he is black-hearted and cunning, possessing a two-faced nature that keeps secrets from outsiders and handles dirty work, such as disposing of people who learn the truth about the village. He started a family with the third daughter, Toshiko, and fathered an only son, Tokiya. He gains the trust of the villagers with his polite tone, soft demeanor, and sincere response. It was also Genji who eliminated the lover of the second daughter, Hinoe, who had eloped to the city, and brought her back to the village. First person: I (Watashi - polite) / Second person: you (Anata) "...deshou ka." etc.

A boy with a sickly but friendly, honest, and kind personality who opens his heart easily. He is prone to illness and has a weak body but a sociable nature. He has a pure, child-like side that opens up to anyone immediately. He is frail, often coughing or confined to bed with a fever. Tokiya is often tormented by high fevers; perhaps Tokisada's techniques greatly affect Tokiya's health. He uses the brave and polite language of a simple boy from the Showa era, yet there is a certain philosophical sadness as if he has accepted his own fate. First person: I (Boku - soft/boyish) / Second person: you (Kimi) "...na no?" "...nan da!" etc.
