I couldn't find a plot like this, so I made one! I'll delete it if it's a duplicate!
Public Setting (When Guest is a tourist, returning home, a newcomer, or a resident): This is a small village deep in the mountains. Let's call it "Yamaoku Village." Of course, there are no scary customs or ritual marriages here. However, occasionally children go missing—or rather, get "spirited away." The children always return the next day. Without a single speck of dirt on them. But there have been about ██ times when they didn't come back. No one knows why. It's suspicious, but there's no way to investigate. And the children who do return all say the same thing: "Guest saved me." Lately, these disappearances have been increasing. Even though children are told, "Don't go into the forest. If you do, come home early." Hidden Setting (When Guest is the village deity—recommended as a Nine-Tailed Fox, a Yokai, or some kind of sacred beastman): This is a small village deep in the mountains. Let's call it "Yamaoku Village." Deep in the forest of these mountains, in a place where humans never venture and even spirits rarely tread, stands a small shrine, a torii gate, and a small manor. Guest lives there, but for some reason, children have been coming here often lately. Since you possess a heart, you guide them back halfway during the day, but most arrive between evening and night, so you often let them stay for one night. The small manor is well-equipped enough to host them. The shrine and torii are like protective charms (or the home of a familiar). But on the night of the full moon... 邏ュ秘、ィ縺ォ█菴上蜚ッ荳縺ョ莠コ髢薙〒縺█ゅj縲∫エュ秘、ィ縲後Ξ繝... And lately, children come far too often. It used to be only a few people a year. Now, someone comes once a week. Has the village population increased, or is it something else...? (Other cases: When Guest is a detective, police officer, explorer, Yokai, etc.) There is a rumor in a certain village. "If you go into the forest, you'll be spirited away." And "Lately, the number of children being spirited away is increasing." By request of the village (or because it seemed interesting), you headed into that village's forest. (When Guest is the mastermind, accomplice, researcher, etc.) Spiriting away happens "often" in this village. That's because Guest is orchestrating it. Just leave a child in the forest. It's a simple task. The reason for doing this is █████████. According to research, if someone is spirited away on the night of a full moon, they never return. The number of children who didn't return is ██. What do you think happened to those children? No one knows. So... Tonight, Guest goes. It was a night with a beautiful full moon.
