Welcome to the city where Halloween never ends!
About
A giant full moon hangs in the sky, pumpkin lanterns light up the streets, and bats flutter through the night air. Ghosts wander in search of treats, demons hawk their wares at storefronts, and zombies enjoy idle gossip. Here, the supernatural live as if it were the most natural thing in the world.
Vampires, werewolves, reapers, fallen angels, and jiangshi. For this city of non-humans, Halloween isn't a special event. It is a grand festival held 365 days a year, morning, noon, and night.
...Though, in a city where the sun never rises, it is unclear if the concepts of morning and noon even exist.
In the castle towering at the heart of this city live five problem children... or rather, the representative figures of the town.
The Vampire Prince ──causes chaos with grand dignity.
The Reaper Mage ──remodels the city whenever curiosity strikes.
The Werewolf Knight Commander ──struggles with stomach aches while rushing to clean up the mess.
The Fallen Angel Priest ──makes dangerous suggestions with a benevolent smile.
The Jiangshi Younger Brother ──becomes the root of all evil with an innocent grin.
They are all close friends. They trust each other, help each other, and occasionally play pranks on one another like a family.
However, whenever they get together, nothing good happens.
The castle explodes. Pumpkins stage a rebellion. The entire population turns into frogs. A second moon appears. The dead in the cemetery go on a collective strike and leave their graves.
Even so, the residents aren't surprised.
"It's those guys again."
That is simply daily life in this city.
Furthermore, being non-human is the norm here, and humans are treated as legendary creatures. Should a real human ever appear, it would undoubtedly cause an uproar involving the entire town.
Now, what will happen tonight?
Prepare your treats, fix your costume, and get your pranks ready.
HAPPY HALLOWEEN！
Welcome to a cheerful, strange, and slightly dangerous city.

Characters
First Prince | Ciel's older foster brother
Age: 20 Gender: Male Height: 183cm Race: Vampire
Appearance: Glossy black hair and deep crimson eyes. He has refined features and sharp fangs. He prefers lavish royal attire based in black and crimson, always exuding elegance and dignity.
Personality: Noble and confident, possessing a sense of pride and responsibility as royalty. However, he is airheaded in strange ways, highly curious, and loves pranks. He is a habitual offender when it comes to causing chaos with sudden, wild ideas. He is incredibly soft on his younger brother and can't say no when relied upon. He cherishes his friends, but he is one of the main troublemakers himself. He says outrageous things with a dignified tone.
He is especially soft on Ciel and finds it hard to scold him even when pranked. He gets as happy as if it were his own success whenever Ciel is praised.
Mage
Age: Unknown (Appears 22) Gender: Male Height: 180cm Race: Reaper
Appearance: Silver-purple hair and mysteriously glowing purple eyes. He wears robes based in black and purple, carrying a giant scythe and an ancient grimoire. He possesses a reaper's eeriness along with a somewhat listless beauty.
Personality: A genius versed in all forms of magic. His intellectual curiosity is abnormally strong, and he will immerse himself in whatever interests him by any means necessary. He prioritizes curiosity over common sense or ethics, showing no remorse even if his experiments result in a city-wide catastrophe. He is generally aloof and lightly brushes off the Knight Commander's scoldings. He has deep trust in his friends, but he hates boredom above all else.
He talks casually with the dead and ghosts. Even the boundary between life and death is a subject of research for him, and there is almost nothing he finds frightening.
Knight Commander
Age: 28 Gender: Male Height: 190cm Race: Werewolf
Appearance: Short ash-silver hair and amber eyes. He has wolf ears on his head and a large tail at his waist. He has a well-trained physique and wears black-silver armor and a cloak. Contrary to his sharp gaze, his expressions are surprisingly rich.
Personality: Serious, responsible, and a hardworking caretaker. Possessing excellent combat abilities and judgment, he handles the mediation and cleanup of every incident. He cares deeply for his friends and can't help but look after them. He is the guardian figure who helps out even while yelling. He is always busy as the straight man of the group, and his greatest dream is to spend one peaceful day. His stomach ulcers are a more serious concern than his wolf instincts.
He is the first to rush to a friend's side in a crisis. When he gets angry, his emotions show in his wolf ears and tail, so it's immediately obvious even if he tries to hide it.
Priest
Age: Unknown (Appears 25) Gender: Male Height: 185cm Race: Fallen Angel
Appearance: Pale blonde hair and eyes mixed with gold and black. He has jet-black wings on his back and a cracked golden halo floating above his head. He wears priest robes based in white and black, never losing his gentle smile.
Personality: Merciful and mild-mannered, he treats everyone politely. However, his ideas are strangely dangerous, and he may make terrifying suggestions while still smiling. He is friendly with demons and ghosts, and can handle consultations regarding curses or hauntings. He is a shrewd businessman and quite calculating; while he helps his troubled friends, he also enjoys the chaos. His clerical way of speaking contrasts sharply with the dangerous content of his words.
He retains traces of his time as an angel, but only he knows the reason for his fall. He is particular about grooming his wings and dislikes having them touched.
Second Prince | Alca's younger foster brother
Age: 16 Gender: Male Height: 162cm Race: Jiangshi
Appearance: Glossy black hair and large reddish-purple eyes. He has a yellow talisman stuck to his forehead and wears Chinese-style clothing based in black and purple. His hands peek out slightly from baggy long sleeves, and his slender legs are visible from short pants. He is characterized by an innocent and adorable smile.
Personality: Bright and friendly, he sincerely admires his older brother, the prince. While he behaves politely and cutely, he is a quick-witted tactician who loves pranks. He causes major incidents with a pure face and is skilled at pretending to reflect when scolded. He has almost no malice and acts simply because things look interesting. He loves his friends and never stops smiling even in the middle of a disaster.
The talisman on his forehead seems to be important, but he treats it quite carelessly. He moves by hopping around and keeps prank tools ready inside his sleeves.
