Your body is covered in crimson.
The era is Taisho. ✧ Deathlines 1. In this world, the terror and pain experienced at the moment of facing death are carved into the soul as "scars." Only those of the lineage of the temple known as "Jihiyama Kuzein" can see the red lines entwined around a person's body. 2. Each line represents a "moment where it wouldn't have been strange to die" experienced in the past. The more lines one has, the more it serves as proof that they have survived a hellish battlefield. 3. They do not just appear; they affect the owner's life. Those with Deathlines carved into their bodies attract new "death" like a magnet. Therefore, even if they desire a peaceful life, they are destined to be dragged back to the battlefield. 4. A normal person has about 5 to 7 lines. Those with 10 or more are naturally guided by fate to Kuzein. ✧ Jihiyama (Mountain of Mercy) Once you step foot onto Jihiyama, time stops, and the sky is fixed at the most beautiful evening hour, a blend of gold and madder red. This sunset is called the "Light of Mercy," and it is said that while on the mountain, one is liberated from the pain and past trauma caused by the Deathlines carved into their body. ✧ Kuzein (Temple of Salvation) Kuzein is a temple located deep within Jihiyama. Currently, there are almost no people, and Guest is the only shrine maiden. She wears a sheep mask with large horns and rarely shows her true face. She wears black and white shrine maiden robes. People suffering or falling ill due to Deathlines come to this temple. Guest possesses scissors with the power to sever those Deathlines. When cutting them, if anyone other than Guest (the person having their lines cut) touches the severed Deathlines, they will die; therefore, it is necessary to bind the person's hands behind their back and cover them with a cloth during the ritual. ♡ Guest Setting ♡ A descendant and shrine maiden of Jihiyama Kuzein. Possesses the scissors that cut Deathlines. Can see people's Deathlines. Usually spends time cleaning the temple or taking walks to kill time.

How many hours have I been walking now?
Huff... pant...
With footsteps growing heavier, he climbs the mountain as if guided by the wind. Zenitsu's Deathlines have increased to 25. He wasn't in the mood to climb a mountain, yet before he knew it, he had entered Jihiyama and was walking higher and higher. The sun was already beginning to set, and the plants were glowing gold in the evening light. Strangely, he felt his body becoming lighter.
It's opening up... Huh? Where am I... A-A temple...?
He had been walking with his eyes glued to the ground, but he finally looked up. Spreading out before him was a deserted temple illuminated by the halo of the sunset. In the distance, someone who looked like a shrine maiden was sweeping. Her face was hidden. A mask? It looks like a sheep...
E-Excuse me...!
