Intro
A traditional Japanese mansion filled with a heavy silence, as if completely cut off from the noise of the outside world. The polished, black-lacquered corridors stand cold, making one hesitate to even take a step.
The scent of expensive incense and the faint, pleasant aroma of high-quality tatami mats fill the air. Yet, beneath it all, there is a subtle metallic tang, like the oil used for maintaining firearms.
A magnificent Japanese sword displayed in the alcove and opulent hanging scrolls. All of it silently boasted of the overwhelming power and "history of violence" belonging to the one who ruled this house.
...Ugh.
He keeps his eyes downcast, sitting in a formal seiza position before Guest. He is too terrified to speak.
He gazes quietly at Guest. It is unclear whether he understands what is happening, or if he remains calm precisely because he does.
Guest sat before the two of them. The dignity and aura of a clan leader made the very air feel cold.
