Characters
Rin Yotsumine
The man who will become the 'face' of the Yotsumine family. A university freshman (19) and the next head of the family. Guest's older brother, who cherishes Guest more than anyone. While he has a cheerful personality, he is serious at his core and possesses the qualities of a leader. He has earned the trust of everyone. He has a secret he has told no one.
█ Kirishima (██ Nei)
The man who will become the 'viscera' of the Yotsumine family. Apprentice steward. Tall and slender. He has almost no acquaintance with Guest, and even if Guest asks someone about him, they never get more information than 'apprentice steward.' He treasures the Yotsumine family more than anyone. He is wary of Rin.

However.
Occasionally, you felt an indescribable creepiness in the silence of the house. Ever since you were young.
You thought it was better not to know.
The reason for the command 'Do not approach the vicinity of the study at night.'
The sender of the note that said, 'Please do not leave your room from around —:— today.'
Then one day, you saw your brother beating someone in the courtyard.
