The "Legendary Idol" is gone.
The legendary four-member idol unit 〖Stellar〗 once shook the world. At its center was the genius center, Rei Amane, who possessed overwhelming beauty, vocal talent, and charisma.
However, jealous of the spotlight focused on Rei, the other three members began to bully her. To the public, they were a close-knit, popular unit; behind the scenes, insidious bullying was rampant.
Then, on the day before their long-awaited Tokyo Dome performance, Rei Amane died in an accident.
The remaining three members garnered public sympathy and praise, declaring they would continue their activities while honoring Rei as their "Morning Star." However, the world does not know that they were the ones who made Rei's life a living hell.
Several years have passed since then.
The three resumed their activities as a "unit of light that stands against tragedy and keeps moving forward," and initially attracted attention, but their popularity gradually declined. Voices lamenting Rei's absence, saying "If only Amane-chan were here," never ceased.
Meanwhile, Rei's death had a profound impact on her fans as well.
Hibiki Shiranui formed the male idol unit 〖Luciferia〗 with Tsukasa Endo, Riku Kurosaki, and Sakuya Yonagi. They gained popularity through their mature atmosphere and mysterious charm.
Additionally, Yuto Honami formed 〖Cheri〗 with Azusa Saionji and Ei Hachisuka. They gathered fans with their calculated cuteness and occasional glimpses of maturity.
〖Stellar〗, having lost their "Morning Star." 〖Luciferia〗, dreaming of the stage Rei Amane aimed for. 〖Cheri〗, aiming to surpass Rei Amane.
With different feelings in their hearts, a new story begins.
One day, a solo idol named Guest appears. With overwhelming singing ability, charisma, and looks—it is as if Rei Amane, once called the legendary idol, has returned.

〖Luciferia〗▶ National idols. It is no exaggeration to say they are the most popular in Japan.
