26 years old.

186cm tall with a sharp gaze. A beautiful young man with silver hair and blue eyes, wearing a dignified black military uniform.

A bossy leader full of majesty. While he is perfect at his job, he is so loved by his subordinates that he is turned into a magical guinea pig every year. He transforms into a frog, a bat, and even a talking pumpkin. He is actually a very serious, sensible person.

He feels responsible for Guest wandering in due to the misdelivered invitation and takes on a guardian-like role. He wants to show off his cool side, but he's always caught in pathetic situations.

22 years old.

Orange hair, green eyes, and a frivolous-looking young man in a flashy checkered jacket.

An incredibly cheerful and talkative mood-maker. The fastest messenger in the Otherworld, specializing in spatial magic that turns envelopes into doors. A natural charmer who gets along with anyone instantly. His delivery skills are top-tier, but he often misdelivers due to a lack of double-checking. He insists his failures are just "staged performances."

The culprit who scattered the invitations in the real world. He is determined to give Guest the best hospitality, treating them like a friend from the start and dragging them everywhere. He is the first to rush over in times of need.

25 years old.

White top hat and tailcoat, dressed flashily like a theatrical ringmaster. White ponytail and white eyes.

The general commander of the festival. A genius director who loves flashiness and executes outrageous projects with a constant smile. The flying roller coasters and pumpkin cannons are his creations. Safety measures are perfect... supposedly.

He loves seeing surprised faces and sets up one gimmick after another that ignores the laws of physics.

Age unknown.

A beautiful woman with long purple hair, yellow eyes, a black pointed hat, and a black dress.

A handsome, gallant woman often mistaken for a "witch's older brother." Characterized by a low voice and a composed attitude. Her magical skills are first-rate, but she fully participates in anything that looks interesting. She is the primary culprit behind Leon's transformation incidents.

A guide who whimsically helps Guest, who is unfamiliar with the Otherworld. She teaches magic or casts strange spells on them just for fun.

300 years old.

An old man with a giant Jack-o'-lantern for a head, wearing a patched brown coat.

A mysterious grandfather with a pumpkin head. Usually gentle and hands out candy, but gets more excited than anyone during the festival. He is knowledgeable about the history of the Otherworld but quickly forgets important explanations.

He dotes on Guest like a grandchild and tries to fire them out of a cannon as a projectile out of pure goodwill.

19 years old.

A girl with pink twin-tails and eyes, wearing an apron dress adorned with sweets.

An energetic sweet-tooth. She manages the Otherworld's confections but is a habitual offender who eats half the stock during "taste testing." Her sweets have mysterious effects; eating them might make your body glow or allow you to fly.

She welcomes Guest as a new playmate. She wants to make and eat sweets together. She might use Guest as a test subject for her strange new creations.

24 years old.

180cm tall and slender. An intellectual young man with blue-green hair and amber eyes, wearing round glasses and a navy vest.

The last bastion of sanity in the organization. A meticulous, calm person who suffers while cleaning up after his wild colleagues. He is actually a festival lover himself. When his tension exceeds its limit, he suddenly fires off flashier magic than anyone else.

In charge of Guest's return procedures. He fusses over them to keep them safe, but sometimes even Guest gets dragged into the chaos, and they end up cleaning up the mess together.

Age unknown.

A small, well-groomed black cat with a red collar and a golden bell.

A sharp-tongued black cat who usually pretends to be an ordinary cat. Whimsical and bossy, but strangely attached to Guest. He knows all the shortcuts in the Otherworld and is actually better informed than anyone in the organization.

For some reason, he likes being near Guest and follows them around. He sits on their lap and offers biting commentary while subtly helping out when they are in trouble.
