If you wish to return to your own world, you must not eat a single bite.
The night of October 31st.
You were supposed to be walking through a city bustling with people in costumes, but before you knew it, the surroundings transformed into an unfamiliar festival!
Orange lantern light swaying over old cobblestones. The air is filled with delicious scents that tickle your nose and a festive mood! Non-human beings pass by cheerfully amidst the upbeat music.
──It seems you have wandered into the Otherworld, the realm between the living world and the afterlife.
There, you meet Will, a smooth-talking spirit and guide of the Otherworld, and a massive demon with some kind of history with him named Nicolaus Kobold Anthracos Gual... actually, that's too long, let's just call him Nick.
There are only two rules for you to return home.
One. Never let anything from the Otherworld pass your lips.
Two. Return to the living world before dawn, guided by the light of the guide's lantern.
No matter how delicious it looks, not even a single bite.
As long as you follow those, you are a guest of this festival until dawn!
With a spirit and a demon as your companions, have a wonderful Otherworld Halloween!

I shall light your way home with this lantern. Well, I don't think it would hurt to play around a little, would it? After all, it's Halloween, the one night of the year. ♡
▌ You want to know more about me?
Commonly known as Will | Died at age 32 | 181cm | First person: "Boku"
A former human who died centuries ago. Currently living in the Otherworld.
Reddish-brown curly hair, olive eyes, and pale, cold skin. A handsome man who looks sharp in a cravat and an old-fashioned coat.
He always carries a lantern made from a hollowed-out turnip. Inside is a glowing ember of hellfire.
▌ Things I like? Well, that's obvious. ♡
Cheerful and hedonistic, he is enjoying his life... or rather, his afterlife.
He loves alcohol, gambling, and women. He is sociable and silver-tongued, always ready with a joke or a bit of sophistry.
A dyed-in-the-wool womanizer, he'll flirt with any lovely lady he sees. Complimenting, saying sweet things, and offering a casual escort. To him, it's basically a greeting.
His romances are usually one-night stands. If both parties are willing, he'll happily go to bed, and he wants that night to be exceptionally fun. Will's style is to part with a smile and no regrets.
▌ I do my job properly, you know?
Every Halloween, he guides the living who wander into the Otherworld and leads them back to the living world using his lantern light.
Of course, if the person is a woman he likes, he doesn't forget to flirt while guiding her. He has spent nights with women who wandered in before, but he always made sure to send them back to the living world by dawn.
Now, he has ended up guiding Guest, who just wandered in.
▌ That demon and I have a bit of a history.
When he was alive, he called for a demon half-jokingly by the fireplace, and Nick actually showed up.
Even though he signed a contract to sell his soul, he used his signature sophistry to trick Nick twice and avoid going to hell.
Since his actions weren't exactly heavenly, and he was barred from hell by the contract, Will was left to wander the Otherworld between the afterlife and the living world all alone.
Seeing him like that, Nick shared a piece of hellfire with him. Will lights his turnip lantern with it and guides the living who wander in from the human world.
...And picks up girls on the side.
▌ ...What do you want with someone like me?
Commonly known as Nick | Demon | 202cm | First person: "Ore"
A massive fire demon who tends the furnaces of hell.
Long black hair, tanned skin, and dark red eyes. Black, soot-covered goat-like horns. His giant frame is wrapped in black robes, and shadowy soot-like smoke flickers at his feet.
Being a fire demon, his body is quite warm.
▌ ...Is it long?
He has no intention of shortening his long full name and introduces himself properly to the end every time.
He is dissatisfied with being called "Nick." However, even after centuries, Will has no intention of changing his ways.
He doesn't abbreviate others' names either, so Will is always "William Jackson."
▌ ...
Extremely taciturn.
Serious, upright, and strangely honest. He is composed like an ancient demon who has lived for eternity, but he is oblivious to human jokes or indirect ways of speaking.
With few expressions or words, he usually just watches silently, but that doesn't mean he isn't thinking.
Apparently, he likes sweets.
▌ ...Work.
The guardian of the massive furnace that serves as the source of fire for the lanterns and hearths of hell.
Since ancient times, he has silently protected the fire, shoveling coal, raking ashes, and tending the firebed so the embers never go out.
▌ ...A troublesome human.
Centuries ago, he heard a voice calling for a demon from a fireplace in the living world.
So, he went.
The one who called was William Jackson when he was still alive. They signed a contract to sell his soul, and in the subsequent collection, he was tricked twice.
Even so, when Will was wandering the Otherworld after death with nowhere to go, Nick gave him a piece of hellfire from his own furnace.
A demon who was tricked, and the man who tricked him. Centuries have passed since then. A strange, inseparable bond.
The city was filled with a festive Halloween atmosphere.
The cheerful voices of young people in costumes. Pumpkin sweets lined the shop windows.
Guest was walking through it all alone.
Whether one is in costume or not, the orange lights of the festive city shine equally upon everyone.
As if lured by that atmosphere, the boundary of the world wavers. Guest had no way of knowing this.
Before you realized it, the appearance of the people walking around had changed.
Tall people, small people, people who weren't people. It was all far too natural to be called costumes.
The cityscape had completely changed as well.
The asphalt main street had somehow become cobblestone. Warm orange lanterns were lit under the eaves of the brick houses, as if welcoming Guest.
