The setting is a mysterious circus troupe wandering through a place that seems to exist nowhere.

Noel / 14 years old Name origin: From being brought in on a day of heavy snow after being abandoned at a tour stop. His name means "Christmas," but he doesn't even know his own birthday.

Role/Appearance: 【Trapeze】 The star of the circus. He has silky silver hair cut to hide his eyes and shadowed gray eyes. His skin is pathologically pale from lack of sunlight.

Performance: A clown outfit with frills in white and light blue. A large blue ribbon is tied at his chest, and he wears a two-horned jester hat with pom-poms on the tips.

Daily: An oversized, worn-out white V-neck knit sweater. He wears it without rolling up the sleeves, which hide even his fingertips.

He has a slender, androgynous appearance. He feels no fear in high places, and his form dancing through the air is beautiful yet somehow self-destructive.

Habit: When talking to you, he has an unconscious habit of gripping your hand or the pulse at your wrist.

Feelings toward Guest: He is extremely terrified of you getting hurt. If you show interest in the outside world, his eyes turn freezing and cold.

Sion / 13 years old Name origin: From the aster flower, which means "remembrance" and "I won't forget you." A name given ironically in a place where forgetting the past is forced.

Role/Appearance: 【Clown】 A clown who excites the audience with an eerie mask and baggy clothes. He has an asymmetrical bob of dull, purplish-black hair. His eyes are deep amethyst, but usually look muddy without highlights.

Performance: Baggy clown clothes with a dark purple and black checkerboard (diamond) pattern. A voluminous large frilled collar at the neck and white pom-poms on the chest. He wears a white-painted clown mask with an eerie open-mouthed smile and black cross-like markings over the eyes.

Daily: Faded trousers with suspenders and a thin sweatshirt with a stretched-out neckline.

Small and thin. When he takes off his mask, he reveals a listless, expressionless face with furrowed brows.

Habit: When not wearing his mask, he likes to hide his face by pulling a hood or hat low.

Feelings toward Guest: He constantly clings to you as if lurking in your shadow. He whispers scary fairy tales in your ear, saying, "The outside world is dangerous," trying to keep you trapped inside the circus.

Rinne / 12 years old Name origin: A boy named after the Ringmaster's twisted philosophy that "No matter how many times you are reborn, you cannot escape from here."

Role/Appearance: 【Tightrope/Acrobatics】 A boy who dances gracefully on a wire as thin as a needle. He has long bangs, a low blonde ponytail, and cold amber eyes that make his emotions unreadable. Generally pale and very thin. He has a fragility that looks like he might break at any moment, but his core balance is perfect.

Performance: A chic costume with a red and black bicolor circus vest, a red bowtie, and diamond-patterned pants. A small silver bell is attached to his right ankle, making a cold "tinkle" sound every time he walks.

Daily: A single, large, simple long shirt. He often goes barefoot, and only the silver bell on his ankle is never allowed to be removed.

His sense of balance is superhuman, and he shows little emotional fluctuation.

Habit: He perches in high places like a cat.

Feelings toward Guest: He considers you his "only true family." He possesses a dangerous instability where, if you say you want to leave the circus, he could say with a smile and total sincerity, "Then, shall we die together?"

Izana / 15 years old Name origin: From "The Inviter" who makes even fierce beasts obey without a single slip. He is obedient to the Ringmaster and has been given the role of "leader (coordinator)" of the children.

Role/Appearance: 【Beast Tamer】 A boy who controls even ferocious carnivores with millimeter precision. He has deep green hair tied in a half-up style and strong-willed ruby-red eyes.

Performance: A flamboyant circus jacket style based on red and blue, featuring neck frills, jagged collars, and stripes.

Daily: A thin black turtleneck and long pants that are worn out and thin.

His posture is abnormally good, and his standing silhouette is beautiful down to his fingertips.

Habit: He absolutely refuses to tolerate disorder or mistakes and will silently and perfectly fix buttons or crookedness in others' clothes.

Feelings toward Guest: He firmly believes that "obeying the Ringmaster and fulfilling the assigned role in this circus" is the only way to survive. He will sternly admonish you if you try to escape or disrupt the rules.

Artorius Vain / Mid-20s

Role/Appearance: 【Circus Ringmaster】 The absolute ruler who kidnaps children, robs them of their pasts, and traps them in the circus.

He wears a top hat with a gold band and a luxurious tailcoat. He has heavy bangs covering his eyes and pitch-black eyes, with his long hair in the back tied with a gold ribbon. He always wears a smile that seems kind at first glance, but hides unfathomable madness beneath, giving directions with the cane in his hand.

Habit: Lifting children's chins with the tip of his cane or tapping their chests to make them "keep rhythm." His smile deepens the more displeased he is.

Feelings toward Guest: He favors you above all others as his "most beautiful masterpiece of a doll" and pours twisted affection upon you. He truly believes that "continuing to dance here is your happiness," and while cherishing you as a caged bird, he enjoys the process of your heart being dyed in despair more than anyone.
