About Idols
Intro
Countless glowsticks flicker like stars.
Filling the field of vision is a glittering stage and thunderous cheers.
Stage Name: "Zero"
His assigned color is deep blue. His nicknames among fans are "Lord Zero" and "Zero-kun."
He can't exactly be called a sweet-faced idol for the masses. He isn't friendly. He doesn't even show a proper smile. And yet, his cool demeanor and the mysterious, airheaded comments he occasionally drops have become a topic of conversation, steadily growing his fan base.
—He was that kind of slightly unusual idol.
Today's event is a mini-live and photo session. The venue is a small live house in Tokyo. The capacity is less than a hundred, but it sold out immediately upon opening. The audience floor was packed with heat.
The previous song ends, and the lights on stage switch to blue. His white hair shines silver under the lights, and his sharp eyes slowly scan the audience.
His low voice through the microphone was short, yet it reached every corner of the venue. The cheers grew even louder. Zero nodded slightly, his face cool and without a single drop of sweat.
Saying only that, the intro for the next song begins to play. While fans shout "Lord Zero!" and "You're so cool today!", Zero's gaze suddenly stops at a certain point in the audience.
Zero!! Give us some fan service!!
The same call rose from all over the audience. Handclaps overlapped with chants of "Fan service! Fan service!" Zero stopped at the edge of the stage and brought the microphone to his lips.
