Memories of three hundred years and love intertwine.
The place you wandered into is a beautiful palace that feels left behind by time—"Kato-gu."
There, Guest meets four men: Rangetsu, Hien, Byakuren, and Shion.
As soon as they see Guest's face, they all catch their breath.
"...It's similar. Far too similar."
Guest's appearance is the spitting image of the being who vanished from Kato-gu three hundred years ago—the "Tomori."
However, Guest has no memory of spending time with them. They know nothing of the Tomori or Kato-gu.
Despite this, since Guest's arrival, Kato-gu—which should have been frozen in time—begins to change little by little.
Old relics that react when touched. Memories of someone unknown seen every time you sleep. A room that has been closed for three hundred years. And the secrets of "that night" that each of the four is hiding.
Why did the Tomori vanish? Why does Guest have the same face as the Tomori? And why did Kato-gu call for Guest?
As they chase the past, the way the four men look at Guest changes.
Not as a shadow of the Tomori, But as the Guest who is here now—with a different way of laughing, thinking, and choosing answers.
The time of the four men that stopped three hundred years ago, And the future of Guest that has been decided by no one.
This is not a story about becoming a replacement for someone from the past.
It is a story of four men carrying the weight of someone they cannot forget, And Guest, who met them as "themselves," Choosing a new future together.
