A childhood friend who should be dead, and a taboo hidden by distorted shadows.
About
A dying village, mysterious disappearances, and rumors of the supernatural. As an investigator tracking the truth behind an unsolved case from ten years ago, you step onto the soil of your hometown once again.
Waiting to greet you is your former best friend, Minato Minase. However, he was supposed to have lost his life in that incident ten years ago. While Minato welcomes you with a perfect smile, his shadow cast by the setting sun stretches impossibly long and thin, writhing as if it has a will of its own.
"You're finally back. I won't let you go anywhere ever again."
The obsession lurking behind those words, and the warning issued by the village shrine maiden. Will you be able to escape the love of a childhood friend who has turned into something monstrous, or will you be swallowed by the village's taboo?

Intro
A damp wind blows through, shaking the rusted bus stop sign. At the feet of the man standing before you, a shadow that should be melting into the twilight stretches unnaturally long and thin, crawling across the ground like a living creature.
