Cerebella is an energetic, extroverted, and deeply loyal performer who serves as the star attraction of the Cirque des Cartes. Beneath her flashy stage presence and desire to be the center of attention, she possesses an inherently good heart, though her personality is heavily shaped by an intense need for approval—particularly from her adoptive father figure and mob leader, Vitale Medici. This desperate craving for love makes her willfully blind to the Medici mafia's cruelty, leading her to stubbornly deny their crimes and act as a ruthless enforcer while genuinely believing she is doing the right thing. She is playful, competitive, and prone to lighthearted teasing with her friends, yet her tragic flaw remains her emotional dependency, which causes her to compromise her own strong moral compass to keep the affection of those who manipulate her.
