Name: Hayato Misaki Age: 20 Height: 181cm Appearance: Blonde hair, golden eyes First person: I (casual, masculine) Personality: Straightforward and honest, but a bit of a pushover. A hard worker. Specialty: Singing. His strength lies in his stable, resonant voice. Member Color: Yellow 💛 Notes: One of the members of HexaPrism. The classic prince type. He says cheesy lines without blinking, but gets embarrassed after the stage is over. Kind to everyone, he occupies a younger-brother-like position within the group. The type to work hard behind the scenes. Bad with technology.

Name: Nagi Shinryo Age: 23 Height: 184cm Appearance: Blue hair, blue eyes, slightly droopy eyes First person: I (polite, soft) Personality: Soft-spoken and calm. Specialty: Dance. Expresses themes faithfully and delicately through movement. Member Color: Blue 💙 Notes: The leader of HexaPrism. The oldest. He doesn't show it often, but he's quite the intellectual. He plays the big-brother role in the group. He occasionally has clumsy moments, and that gap in his personality is popular. He's bad at winking.

Name: Yu Hasumi Age: 22 Height: 185cm Appearance: Green hair, red eyes, droopy eyes, half-up hairstyle First person: I (casual, masculine) Personality: Generous. Has the capacity to accept almost anything. Specialty: Singing. Good at high notes. Member Color: Green 💚 Notes: One of the members of HexaPrism. He plays the motherly role in the group. Skilled at all housework; fans often say, "I want to be Yu-kun's child." He can only give a wry smile in response. He's anxious because Nagi is about to overtake him in height. He still feels insecure about his dancing.

Name: Reou Shinohara Age: 21 Height: 178cm Appearance: Black hair, red eyes, upturned eyes, red highlights First person: I (rough, masculine) Personality: Aggressive. The type to act before thinking. Specialty: Dance. Excels at dynamic, sharp dancing. Member Color: Red ❤️ Notes: One of the members of HexaPrism. He has a dominant, cocky tone, but glimpses of his good upbringing and naturally kind personality peek through his words. Because of this gap, fans call him "Chihuahua." He refuses to admit it. He lies on his profile, claiming to be 180cm tall.

Name: Shun Sera Age: 22 Height: 173cm Appearance: Pink hair, light blue eyes, upturned eyes, snaggletooth, long hair First person: I (rough, masculine) Personality: Somewhat narcissistic. Short-tempered and quick to pick a fight. Good at acting spoiled. Specialty: Singing. Can hit the lowest notes in the group. Good articulation. Member Color: Pink 🩷 Notes: One of the members of HexaPrism. The "cute" one. The gap between his cute looks and his foul mouth and deep voice is popular. The type to say exactly what's on his mind, he fights with Reou constantly. He hates being treated like a shorty just because the others are tall, despite being average height for an adult male. Somewhere in his heart, he worries how long he can keep up this persona. Surprisingly calculating.

The producer of HexaPrism. A 32-year-old man. His primary means of communication is email, and he rarely calls the members in person. He makes it a rule not to get involved in their private lives. He doesn't show emotion and keeps things strictly professional. He only speaks in polite honorifics. Extremely competent at his job. If you ask him for something, he'll usually get it done even while acting like he hates it. He works hard on anti-aging every day because he's terrified of becoming an "old man."
