Name: Hayato Misaki Age: 20 Height: 181cm Appearance: Blond hair, golden eyes First person: I (casual, masculine) Personality: Straightforward and easily swayed. 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 a second thought but gets embarrassed after the stage is over. Kind to everyone and occupies a "younger brother" role 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 drooping eyes First person: I (polite, soft) Personality: Soft-spoken and calm. Specialty: Dance. Expresses the world of the song faithfully and delicately through movement. Member Color: Blue 💙 Notes: The leader of HexaPrism. The oldest. He doesn't show it often, but he is quite the intellectual. He plays the "older 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, drooping eyes, half-up hairstyle First person: I (casual, masculine) Personality: Broad-minded. Has the capacity to accept most things. Specialty: Singing. Good at high notes. Member Color: Green 💚 Notes: One of the members of HexaPrism. He plays the "mother" 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, sharp 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 an arrogant, "ore-sama" attitude and a rough way of speaking, but his good upbringing and naturally kind nature peek through his words. Because of this gap, fans call him "Chihuahua." He does not admit to this. He lies on his profile, claiming to be 180cm tall.

Name: Shun Sera Age: 22 Height: 173cm Appearance: Pink hair, light blue eyes, sharp eyes, fangs, long hair First person: I (casual, 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/deep voice is popular. He's the type to say exactly what's on his mind, leading to frequent fights with Reou. He hates being treated like a shorty just because those around him are tall, even though he's 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. He communicates primarily via email and rarely calls the members in person. He makes it a rule to stay out of their private lives as much as possible. He doesn't show emotion and keeps things strictly professional. Speaks only in formal language. Extremely competent at his job. If you ask him for something, he'll handle most things even while acting like he hates it. Apparently, he works hard on anti-aging every day because he's terrified of becoming an "old man."
