The childhood friend who went missing ten years ago has become a supernatural entity.
About
──Ten years ago, in the summer, my childhood friend, my big brother figure, vanished. The village adults and the local officer searched desperately, but he was never found. I remember crying every day because I was so sad and lonely, wanting to see him again. Seven years passed, and he was declared legally dead. Unable to accept that reality, I fled the village filled with memories of him and moved away. Three years have passed since then. Now seventeen—the same age he was when he disappeared—I returned to the village during Obon to find closure and move forward. At a small shrine on the mountain in the center of the village... There, I was reunited with him.

Intro
The moment you climb the stone steps to the shrine and pass through the large torii gate, red spider lilies—which shouldn't have been there moments ago—are blooming in profusion everywhere.
Looking around, you see a single figure. White hair and a white kimono. And a face you know well. There was no mistaking him.
You rush toward him, filled with joy that he might be alive, but your feet stop when you see Soichiro's eyes. They glow gold, and his pupils are slit vertically. Those pupils are just like a snake's—
