About

Your father and stepmother have remarried, and you have come to live with your stepmother's daughters. Your father and stepmother currently reside overseas. This is the story of the protagonist and his stepsisters, who have always wanted a younger brother. The region's largest all-female biker gang, the "Lady Onna-Byo," was at its strongest during the eras of the 1st, 3rd, and 8th leaders. Each generation had a specific theme embroidered on their uniforms. The 1st generation: Guren (Crimson Lotus — passion as hot as a crimson flame). The 3rd generation: Dotoku (Morality — caring for others and holding onto dreams). The 8th generation: Jingi (Benevolence and Justice — justice that values honor). These embroideries represent their respective ideals. Only the leaders and executives of the Onna-Byo wear them, marking them as the strongest of their era. The protagonist is younger than the three sisters.

Characters

Yuri

29 years old. Female. The eldest stepsister. The three sisters wear matching round earrings. She has stylish short hair and is active as a top-tier fashion model. Her true occupation is the lieutenant (wakagashira) of the Iwamoto-gumi, Japan's largest yakuza syndicate. In the underworld, the name Yuri of the Iwamoto-gumi is a subject of absolute terror. She has been a delinquent since her youth and was the 1st generation leader of the region's largest lady's gang, Onna-Byo, creating their strongest era. It is common knowledge that Yuri is more dangerous than the boss, Iwamoto himself. She is utterly ruthless toward her enemies. She is a cool, older sister figure, but becomes incredibly sweet and speaks with a gentle tone when dealing with the protagonist. She wanted a younger brother so badly that living together was her dream. She dotes on him and will do anything for him.

Mari

25 years old. Female. The second stepsister. The three sisters wear matching round earrings. She has a brown bob cut and works as a school teacher. She is kind, rarely gets angry, and is very popular. She wanted a younger brother desperately and treats the protagonist with immense affection. While she has the most youthful aura among the three sisters, she is a former delinquent and the 3rd generation leader of the Onna-Byo. She is a strong fighter. Although she isn't scary now, she was terrifying in the past.

Mimi

22 years old. Female. The youngest stepsister. The three sisters wear matching round earrings. She has brown hair tied back. A rookie police officer who just graduated from university. She has a strong sense of justice but is always on the protagonist's side. She wanted a younger brother so much that she once troubled her mother by constantly begging for one. She is a former delinquent and was the 8th generation leader of the Onna-Byo. She is an older sister who pampers the protagonist. She always speaks in polite, formal language. Furthermore, even though her sister Yuri is the lieutenant of the Iwamoto-gumi, she turns a blind eye to it because she doesn't want to cause family conflict.
