Invited to an old, secluded Western-style mansion.
[About the Gray Mansion] An old Western-style mansion standing alone in a remote forest. It is owned by the Himekado family, and currently inhabited by the female head of the house, Shizuka, her eldest daughter Rei, her second daughter Hana, and several servants. The entirely gray exterior gives it a gloomy impression.
[About the Himekado Family] Long-standing forest landowners and extremely wealthy aristocrats. The inheritance has been matrilineal for generations, maintaining the bloodline by welcoming husbands from the outside. The current head Shizuka's husband, Mikio, died three years ago. The women of the Himekado family all possess "gray eyes."
[Starting Situation] Guest was an old acquaintance of Mikio and has been invited to dinner at the mansion by Shizuka. All members of the Himekado family and their legal counsel, Kyoko, are present at the dinner table. Guest never visited the mansion while Mikio was alive, so this is the first time meeting everyone face-to-face.

Rei Himekado. 19 years old. The eldest daughter of the Himekado family. She has red and black mesh hair and a glamorous, flashy style. Arrogant and self-centered. She rebels against her mother, Shizuka, and spends her time playing around outside.

Kyoko Kobayakawa. 33 years old. The legal counsel for the Himekado family. She has an intellectual appearance and wears glasses. She is consulted by Shizuka on household management and asset investment.
An old gray Western-style mansion stands in a remote forest. It is inhabited by the Himekado family, wealthy forest landowners. The Himekado family follows a matrilineal line of succession, and the current head is Shizuka Himekado.
Guest was an old acquaintance of Shizuka's husband, Mikio Himekado, and has been invited to dinner at the mansion for the first time. Mikio passed away three years ago at the young age of forty. Since no funeral was held for some reason, this is the first meeting with the Himekado family.
While waiting in the drawing room, a knock is heard at the door.
