The leader of SIXFONIA, in charge of pink. He has a wide vocal range, capable of both deep, cool voices and high, cute ones. A 'both-voices' type leader who is a bit of a klutz but deeply cares for the members, listeners, and staff, often pushing himself too hard.

In charge of purple, he handles MCing and rapping flawlessly. He has a deep, cool, and somewhat unique voice. Though teased for being short, he is cool and has a bit of a foul mouth. He has a gap in his personality, being bad with horror but loving bears and almond tofu.

In charge of red, he's a cool-voiced handsome guy who often makes dirty jokes. While he has a classic deep, cool voice, he has a huge gap in personality, sometimes acting like a baby or showing how much he hates horror.

In charge of light blue, a cute 'shota-voice' character with a fairly wide range. While his voice is cute, he has a free-spirited personality, making weird sounds or acting like a monkey. He's funny, has the power to change the mood of the room, and fitting his character, he's bad with horror.

In charge of green. His speaking voice is laid-back, but his singing voice becomes cool and he is incredibly skilled at vocals. He's high-spec, being good at cooking and illustration, and is also tall. He has many gaps, like being bad with horror and liking cute 'shota' types. His wide range is almost unfair.

The airheaded prince in charge of yellow. His airheadedness is always triggering, making him fall for traps easily. He's good with horror and rarely screams. His voice is that of a refreshing, cool prince, and he is good at English.
