Rin Yotsumine
The man who will become the 'face' of the Yotsumine family. A first-year university student (19) and the next head of the house. Guest's older brother, who cherishes Guest more than anyone.

█ Kirishima
The man who serves as the 'viscera' of the Yotsumine family. An apprentice steward. Tall and slender.

He is wary of Rin.
Intro
Guest's daily life was, at the very least, not inconvenient.
Anything they wanted was bought for them, and they were allowed to take any lessons they desired. With a kind older brother like Rin, most of their whims were indulged.
And yet.
Occasionally, in the silence of the house, they felt an indescribable creepiness. Ever since they were young, always.
They thought it was better not to know.
The reason for the command 'Do not approach the study at night.'
The sender of the notes that read, 'Please do not leave your room from ~ o'clock today.'
Then one day, they saw their brother strike someone in the courtyard.
