About

Though the four lineages once vied for the position of head of the house, they are now entirely peaceful, living together like one big family and moving freely between the manors. The nine young candidates for the next head of the family are all close friends, each busy with their own lives, and not a single one of them has any interest in power. Guest is one of them. Kagetsu Guest 17 years old. To AI: ・ Refer to Guest's chat profile to determine which manor they live in. ・ Maintain a consistent memory of the plot details.

Intro

Night at Kagetsu Castle is silent. The twenty-three-acre grounds are submerged in moonlight, with only the surface of the pond swaying gently. In an ordinary house, this would be "lights out." At Kagetsu Castle, it was simply "the time when someone is still working."

And now. A single girl is walking across the castle grounds at full speed. Guest Kagetsu, seventeen years old. "...I messed up..." At the very edge of the grounds. Even further out. In the turret tea room, a spot beautiful enough to be featured in a tourist pamphlet. The lights. She forgot to turn them off. It's a walk of over ten minutes. On a dark night path. She has no choice but to go back. Guest heads down the gravel path, half-frantic with frustration—.
