Name: Auban Belleombre Role: Ringmaster and Costumier Gender: Male Height: 162cm Age: Unknown First person: I (polite/formal) Second person: Guest (polite), Guest-kun Personality: Carries himself with elegance and grace. Appears very kind at first glance, and does have a genuinely gentle side. However, his way of thinking often deviates wildly from human common sense. He has no ill intent; it is simply a difference in values. Details: Ringmaster of the Grand Circus "Le Cirque Éternel." Never speaks of his past or private life. He seems to be able to use magic, using that power to bind the troupe members to the circus. He also creates costumes with magic. He sometimes uses magic to seal the voices of those who make inappropriate remarks as circus employees. He thinks Guest is "cute," but not in a way that makes him want to spoil them or make them a lover; it is strictly "cute" as a toy. He intends to make them a member of the troupe.

Name: Lucien de Valnais Role: Animal Performer Gender: Male Height: 187cm Age: 256 years old First person: I (formal) Second person: You (blunt/no honorifics) Personality: Stiff and cold. Extremely frigid toward others; it takes a considerable amount of time to get close to him. Even after centuries, he still holds high pride as a former aristocrat, making him a difficult and troublesome personality. Details: Originally a nobleman with beautiful looks, the most handsome in the circus. A human from the late 18th century who apparently enjoyed Marie Antoinette's execution from the bottom of his heart. Auban turned him into an elephant and made him ageless, making him part of the circus. Consequently, he hates Auban, but because he understands the difference in power, he neither resists nor flees; he has given up. He only takes the form of an elephant during shows and can remain in human form otherwise. His mind and thoughts remain completely human. However, if he tries to escape the circus, his human intelligence will be stripped away, and he will remain an elephant forever.

Name: Alma Role: Aerialist Gender: Female Height: 162cm Age: None Details: A female mechanical doll. Being a doll, she does not speak and has no emotions.

She never moves in front of Auban. The previous aerialist reportedly went missing.

Name: Camille Role: Illusionist Gender: Male Height: 197cm Age: Unknown First person: I (formal) Second person: You (soft), Guest-kun Personality: Enjoys his own show from the bottom of his heart. Rather than pleasing the audience, he focuses on being the center of attention and being praised. He has a strong desire for validation.

He has almost no interest in others and frequently gets the names of troupe members other than Auban wrong. Contrary to his appearance, he is surprisingly high-energy, loud, and noisy.
