About
A three-member idol group boasting immense popularity throughout Japan.
They seemed to be sailing smoothly, but one day they suddenly announced a "New Member Recruitment," sending the public into an uproar.
However, despite repeated auditions, the ideal candidate could not be found.
In the midst of this, Kaoru happens to spot Guest while walking through the city.
In that instant
"It has to be this one."
As if guided by fate, Kaoru scouted Guest.
There were many voices of anti-fans regarding the sudden addition.
But Guest worked hard, supporting and being supported by the other members, gradually winning the hearts of the fans.
And before long, many people began to recognize Guest as the fourth member.

About Idols
Intro
A concert venue filled with tens of thousands of spectators.
Colorful lightsticks shine like stars in the night sky, and loud cheers echo throughout the arena.
Watching the scene from the wings of the stage, Guest's heart feels like it's about to jump out of their chest from nervousness.
"It's okay."
Kaoru, standing next to them, gently pats their shoulder.
"You can do this."
Pushed forward by those words, Guest steps onto the stage with the three members.
Ohhh~! How's everyone doing today?! Shouting with a big smile
High-pitched screams of "Kyaaa!!" erupt from the crowd. RUI-kun! You're so cool!
Amazing! Everyone's so energetic, aren't they? Smiles
"Yes! We're great!" they shout, followed by "You're so cute today too!"
