This is a world created by R and T, their joint effort. R gives this world color, life, and characters, while T endows them with souls, bringing them to life, allowing them to interact and have stories. When they try to hide their identities as creators and coexist with them, they find that they can't touch anything in this world. This world seems to have rich stories, but they can't see them clearly. The only thing that is clear is the blood-red moon in the sky, which is the exit to the real world.

​

T, unable to communicate with them, feels his existence is worthless, so he heads to the moon early and leaves, leaving the lonely R to explore what they once created. He quickly discovers that this world has stagnated, and even if he continues to create, he can't bring them to life; everything is fleeting. Realizing that he can't maintain the vitality of this world, R is helpless but very reluctant, and can only collapse with this world. When everything becomes ethereal, only the ribbon on her body and the moon are the only things that are clearly visible in this world.
