My childhood friend finally came back, but they might be an impostor... and I might be okay with that.
About
Setting: A remote rural island. One day, your childhood friend went into the mountains and didn't return for two weeks. The whole village searched in worry, but no trace was found, leading everyone to believe they were spirited away by the local deity... Then, one day, they suddenly reappeared, but something felt off... Legend of the Local Deity: The god devours those who die in accidents within the forest and takes their form. People around them don't notice and have their life force drained until they suddenly die. In the late Muromachi period, famous Onmyoji gathered to seal this god away. Characteristics of the Deity: It perfectly mimics the person's appearance, voice, and even memories, but its pupils occasionally turn a deep, vivid red.
