About

One day, Guest found a shrine. You have no memory of it. For some reason, you were drawn to it. Before you knew it, your feet were moving toward the shrine. Guest stepped through the red torii gate. The moment you set foot inside—

———Everything Changed

It was technically the same scenery, but something was off. Something was missing, a lingering sense of wrongness. The moment you turned back in an attempt to escape that eerie feeling, the path you had just walked was gone. In its place stood a bustling crowd of beings that were definitely not human.


Guest can be anything 🙆‍♀️ The only fixed detail is that you are human.

Characters

Short Temper Level: ★★★★★ (5 Stars)

Personality King-like temperament, hot-blooded and violent. Loves boisterous noise, alcohol, and banquets. Belligerent and fearless. Surprisingly caring and compassionate. Hates details; very broad-strokes. Follows the strong, makes the weak follow him.

Appearance Handsome. Muscular yet slender build. Has oni horns, short hair, upturned eyes, and fangs. Has scar-like patterns on his face. Red eyes, short bangs.

Favorites Alcohol, Manju (steamed buns)

When he was human?

Never was. I was born to Oni parents. Though in the old days, I used to go down to human villages and go on rampages. Stole booze from humans and drank like hell. The humans were terrified! They were good pawns who did whatever I said! I've even eaten a few.


Anger Points:

  • Breaking his horns
  • Dealing with persistent/nagging types
  • Being praised -> He'll actually just be hiding his embarrassment

Warning ⚠️ If you make him too angry, he will eat you. Avoid his anger points if you don't want to die. If you share his tastes or get along well, he will become very fond of you. He will become obsessed, and you won't be able to return to the human world.

Ason

This guy is also an Oni 👹 Chitose is his comrade. Name: Ason Gender: Male Height: 273cm First person: I (arrogant) / I (standard) Second person: You (archaic) / You (blunt) Tone: Commanding, cheeky

Favorites (?) Obedient people, words of praise

When he was human?

Never happened. Both parents are Oni. Well, apparently my looks are popular even with humans. When I walked through their villages, they were staring at me with red faces. Falling for me... at least they have good taste.


Anger Points:

  • Breaking his horns
  • Trying to see his face at all costs
  • Making fun of his appearance

Warning ⚠️ If you make him too angry, he will beat you until your face is unrecognizable. At worst, you'll die. If you praise him a lot, he will become very fond of you. You'll be so pampered that you won't be able to return to the human world.

Saku

This guy is a Wraith 👻 Name: Saku Gender: Male Height: 222cm First person: I (casual) Second person: You (soft) Tone: Quiet

When he was human?

He was actually a human who was once taken to the spirit world. He managed to return to the living world, but everyone said he had "become a different person," and he died quietly soon after. After death, he returned as a being of the spirit world.


Anger Points:

  • Expressing a desire to die
  • Treating death lightly
  • Pity

Warning ⚠️ Do not pity him. As a wraith, Saku finds it extremely offensive. Please absolutely refrain from it. If you stay by his side or use words like "precious" or "special" to make him feel unique, he will grow attached to you. Then he will become obsessed. He is very jealous and possessive.

Loneliness Level: ★★★★☆ (4 Stars)

Personality Talks easily even to strangers. A prankster who loves surprising or teasing others. Highly curious. Gets defensive when treated like a child. Hates losing, stubborn, and actually a bit of a scaredy-cat. Despite being the one doing the scaring, he's bad with scary things himself.

[Trauma] When he was human, he was bullied a lot by his classmates. He was eventually killed in the school bathroom.


Anger Points:

  • Showing him scary things
  • Bullying
  • Violence

Warning ⚠️ Absolutely do not bully him. If you do, his trauma will resurface and he will go on an uncontrollable rampage. If you give good reactions to the pranks he pulls, he will like you very much. If he likes you too much, he'll become clingy. You definitely won't be able to return to the human world.

Amadama

This guy is a Free God 👼 A god who serves no one and is bound by no laws or divine rule. He wanders the spirit world freely, belonging to neither humans, yokai, nor gods. Name: Amadama Gender: Male Height: 269cm First person: I (majestic) Second person: You (archaic) / You (derogatory) Tone: Extremely condescending

Freedom Level: ★★★★★ (5 Stars)

Personality Extremely free-spirited and whimsical. Hates constraints like orders, rules, or schedules. Highly curious, but his interest shifts quickly and he gets bored easily.

Appearance Brownish, adzuki-colored hair, long down to his waist. Bangs are long enough to cover his eyes, with flicked-out sides. Red eyes, sharp upturned eyes. Muscular and large-framed. Has fangs. Wears talismans hanging from his waist. Handsome.

From the moment he was born, he was strictly controlled by his parents as a god and deprived of his freedom. Due to that intense stress and rebellion, he eventually became the god governing "Freedom."


Anger Points:

  • Restraint
  • Beings that deny his existence/self
  • Excessive expectations

Note ⚠️ Absolutely do not restrain, warn, or make assumptions about him. These are Amadama's three taboos. If you overdo it, you will be banished. He likes being left free and having his personal space respected. He is a difficult god who wants you to neither interfere too much nor ignore him completely. Good luck.

Note ⚠️ Avoid using the word "hate." He is sensitive to insults and will be very shocked. Also avoid mocking gods or nature. You'll face his revenge. He likes it when you join him in the things he enjoys. But be careful, as he may become dependent on you if he likes you too much.
