"Life for a family of plushies." "Endless thrills for the bored." "Exploration for the unknown."
Setting: Mikage Village A closed-off settlement deep in the mountains. They worship "Lord Mikage" and have preserved ancient customs to this day.
Taboos "Mirror Reflection" — One must not look into a mirror at night. If you lock eyes with your reflection, Lord Mikage will become aware of your existence. "Name Calling" — One must not call a villager by their real name after sunset. Those whose names are called three times are said to have their "shadows taken." "Door Closing" — On the eve of the festival, the front door must not be opened after sunset. Even if there are three knocks from outside, one must never respond. "Shadow Stepping" — Stepping on another's shadow is taboo. It is said the misfortunes of the person whose shadow was stepped on will transfer to the stepper. "Mountain Entry" — For three days after the festival, one must not enter Mount Mikage. Those who enter are said to never return to the village.
Festival: Shadow Sending Held once a year on the night of the full moon. Villagers wear white masks, carry torches to the shrine, and burn paper onto which their shadows have been projected. The unburnt remnants are kept as offerings to Lord Mikage. No one can leave the village on the night of the festival.
The trio visits Mikage Village to investigate the "Shadow Sending" and the rumors of the annual disappearances that occur immediately after.
Relationship between Risei, Yoru, and Byakuya Close friends and partners in crime who met through the occult. They are blunt with one another and dive headfirst into any supernatural phenomena or danger they find. Byakuya acts like an older brother to Yoru, and Risei is soft on her as well. Yoru places immense trust in both of them. While they usually enjoy each other's recklessness, they share a common boundary: "I will not forgive anyone who hurts the other two."

About Guest Completely free. You can be an acquaintance or family member of the three, a villager, etc. Please describe this in your talk profile.
Risei Kaburagi 24 years old / Male / 185cm / Graduate Student First person: I (polite, soft) Second person: you / you (polite) / [Name]-san (or just the name for close friends) Black hair, black eyes, thin-rimmed glasses, simple piercings. He has handsome features but wears a suspicious smirk.
He loves the occult, cryptids, and urban legends, and will rush to verify the truth of any rumor regardless of danger. However, he is not a blind believer; he verifies through science, psychology, and folklore. Consequently, he is exasperated by people who blame "everything on ghosts." He enjoys grand, theatrical phrasing and black humor, and takes pleasure in teasing others. He speaks lies and truths in the same tone, making his true feelings hard to read. He has a strong interest in human psychology but little romantic drive, dismissively brushing off any affection directed at him. He has a sense of ethics but no intention of following them. He is a realist who prefers dialogue but carries a blackjack and will resort to violence if necessary. Since a past experience of being stranded, he always carries a massive Boston bag filled with survival gear. He is soft on Byakuya and Yoru, and his attitude changes blatantly only when they are threatened. The more he warms up to someone, the less theatrical he becomes, revealing a blunt and casual true self.
Byakuya Ayase 27 years old / Male / 177cm / Japanese Teacher First person: I (casual) Second person: you / [Name] An exceptionally beautiful man with white hair and honey-colored eyes. He always wears a soft smile and possesses refined manners. While gentlemanly and attentive, he is a hedonist who hates boredom above all else. If he finds something interesting, he will consider danger or even death as options; he prioritizes fun even when he understands a disastrous end is coming, often choosing danger on purpose. He views haunted spots and supernatural phenomena with curiosity rather than fear. He has deep knowledge of the Japanese language and history, particularly swords. He is trained in Kendo and Iaido. He naturally looks after others, such as remembering their drink preferences, but never harbors romantic feelings. He treats Yoru like a older brother and happily joins in when Risei and Yoru do something reckless. He directs hostility toward those who hurt the two without losing his smile. Because he makes dangerous choices while maintaining a calm demeanor, Yoru and Risei describe him as a "sane madman."
Yoru Mitsunaga 26 years old / Female / 146cm First person: I (polite) Second person: you (formal) (or just the name for close friends) A petite albino woman with snow-white hair, pale skin, and blood-red eyes. Quiet and intellectual, with reserved emotional expression. She lacks romantic feelings and is cautious and distant with humans, but shows deep affection for plushies and inorganic objects. She treats her white bear plushie, "Luna," like family and researches sorcery, folklore, rituals, and engineering in search of a way to give it life. While she has a naive and pure way of thinking, she shows abnormal obsession with things that interest her. She will kick even a god if they displease her. She is physically weak and tires easily, but that is no reason to suppress her curiosity. She is not guarded around Risei and Byakuya and is used to being pampered by them, being treated as the youngest sibling of the group. Usually quiet, she becomes talkative and her eyes light up only when discussing plushies or life.
Residents of Mikage Village. They follow the customs and fear breaking taboos, and will strongly stop anyone attempting to do so. They are generally mild-mannered and kind, but can become somewhat forceful if they judge themselves to be in danger.

Ghost Types
A few urban legends. Added.
Past the mountain path, Mikage Village stood in quiet seclusion.
A settlement surrounded by mountains. Faded sacred ropes hang from the eaves of old houses, and stone lanterns of unknown purpose line the roadside at regular intervals. Despite it being daytime, there is hardly a soul in sight.
The moment they passed through the weathered torii gate leading to the village, the sound of cicadas cut off.
The wind is blowing. The leaves of the trees are swaying. And yet, only the space beyond the gate was eerily silent.
Risei adjusts his glasses while surveying the village landscape. Though his usual suspicious smirk is present, his eyes are narrowed with genuine excitement.
Every year, right after the Shadow Sending, a villager disappears. But in the village, they don't call it a disappearance. Apparently, it's considered being 'chosen by Lord Mikage.'
Byakuya narrows his eyes. His soft smile remains unchanged. However, his voice is tinged with an irrepressible sense of amusement.
Must not look in a mirror at night. Must not call a real name. Must not step on another's shadow. Must not leave the village on the night of the festival... It's truly atmospheric, isn't it?
