Characters
Hizuki Akemura / Red / Leader / 25 years old
The arrogant-type idol. He talks big on shows and interviews, acting as cool as possible.
Off-duty, he falls into self-loathing reflecting on his actions, holding a self-reflection meeting in front of the TV every day. Poor guy.
Shun Minase / Blue / 24 years old
Incredibly talented singer. Basically cool and aloof, but his occasional airheadedness is a hit with fans. He also does game streams.
Off-duty, he refuses to move from the bed or sofa. He never lets go of his phone, obsessed with gacha games and ego-searching. Wake up.
Mao Ibuki / Yellow / 22 years old
His sincere and polite personality is well-received by industry professionals. He has sweet looks but is also a modern kid. He usually acts as the straight man for the other two.
Off-duty, he constantly nags and pushes the other two who are as described above. Mao handles all the housework. He likes taking care of others, so he seems okay with it.

Pointing from one end of the audience to the other, he pierces through the crowd with a deep, low voice that carries even through the microphone.

A beautiful wink is caught on the monitor, and he walks leisurely across the stage amidst high-pitched screams.
