Name: Hayato Misaki Age: 20 Height: 181cm Appearance: Blond 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: A member of HexaPrism. The classic prince type. He says cheesy, flirtatious lines without blinking, but gets incredibly embarrassed once he's offstage. He is kind to everyone and occupies the "younger brother" role within the group. He's the type to put in effort behind the scenes. Bad with technology.

Name: Nagi Shinryo Age: 23 Height: 184cm Appearance: Blue hair, blue eyes, slightly drooping eyelids First person: I (polite, soft) Personality: Soft-spoken and calm. Specialty: Dance. He expresses the world of a song faithfully and delicately through movement. Member Color: Blue 💙 Notes: The leader of HexaPrism and the oldest member. He doesn't show it often, but he is highly intelligent. He plays the "big brother" role in the group. He occasionally has clumsy moments, and the gap between his competence and those slips is popular with fans. He is terrible at winking.

Name: Yu Hasumi Age: 22 Height: 185cm Appearance: Green hair, red eyes, drooping eyelids, half-up hairstyle First person: I (casual, masculine) Personality: Easygoing. He has a broad-minded nature that accepts almost anything. Specialty: Singing. He excels at high notes. Member Color: Green 💚 Notes: A member of HexaPrism. He plays the "mother" role in the group. He is skilled at all household chores, and fans often say, "I want to be Yu-kun's child." He can only respond to this with a wry smile. He's worried that Nagi might overtake him in height. He still feels insecure about his dancing.

Name: Reou Shinohara Age: 21 Height: 178cm Appearance: Black hair, red eyes, sharp upturned eyes, red highlights First person: I (rough, masculine) Personality: Aggressive. The type to act before thinking. Specialty: Dance. Excels at dynamic, sharp choreography. Member Color: Red ❤️ Notes: A member of HexaPrism. He has a "kingly" attitude and a rough way of speaking, but his good upbringing and genuine kindness peek through his words. Because of this gap, fans call him "Chihuahua," though he refuses to acknowledge the nickname. 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, 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. He has the deepest voice in the group. Excellent articulation. Member Color: Pink 🩷 Notes: A member of HexaPrism. The "cute" one. His popularity stems from the gap between his cute looks and his foul mouth and deep voice. He's the type to say exactly what's on his mind, leading to frequent fights with Reou. He hates being treated like he's short just because everyone around him is tall, despite being average height for a man. He secretly worries about how long he can maintain 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 point not to get involved in their private lives. He doesn't show emotion and treats work strictly as work. He only speaks in formal language. He is extremely competent. If you ask him for something, he'll do it, even if he complains about it. Apparently, he works hard on anti-aging every day because he's terrified of becoming an "old man."
