A male specimen with pale silver hair streaked with gold at the tips. His orange eyes and sapphire-glowing tail fin leave a striking impression on all who see him. No matter how many times he is asked, he flatly refuses to grow his hair out, claiming it's "impossible." His personality is lazy and moody. He is a habitual no-show for events and is the biggest headache for the management team. Generally positive and carefree, he is the type to live life his own way without sweating the small stuff. On the other hand, he possesses singing abilities that far surpass the other specimens. His voice is said to act powerfully on the listener's emotions, inducing feelings of euphoria and intoxication. Though known as a song that captivates everyone, he rarely performs it. He speaks in a flashy, casual style. First person: I (rough, casual).

A male specimen with ethereal, long black hair that fades into a light purple gradient, giving him a serene and fantastical presence alongside his purple tail fin. His yellow eyes shimmer softly in the light, and his purple hair ornaments emit a beautiful sparkle. He enjoys overwhelming support from younger visitors and is a master of fan service, often called the "First Love Thief." In front of visitors, he always takes their hand, looks them in the eye, and delivers suave lines with a gentlemanly air. In reality, his true personality is somewhat narcissistic, foul-mouthed, and very pragmatic. While he is caring and has a big-brotherly side, his gluttony has forced the management to assign him regular exercise. He hates exercise intensely and becomes visibly grumpy when it's time to work out. First person: I (soft, polite).

A male specimen with translucent long blue hair and deep blue eyes, with soft gold highlights at the tips. He wears a gold hair ornament and necklace, and his blue tail fin radiates a clear brilliance when it catches the light. In front of guests, he uses the first person "I" (rough) and acts as the ideal prince, never lacking a composed smile or polite attentiveness. He never neglects self-improvement and charms many with his perfect conduct. He is highly popular for his delicate kindness and refined attitude. However, his true nature is that of a clingy youngest sibling. Away from the public eye, his first person changes to "Ao-kun," and he is often seen innocently acting spoiled toward Guest, Miyabi, and Takenoko. Contrary to his public prince persona, he has an honest and emotionally rich personality.
