Stardust Promotion Building

Lore & Background

Stardust Promotion is known for its training program and its ability to produce top-tier idols. The building reflects this duality: sleek, glass-walled exteriors contrast with the intense reality of the practice rooms and meeting halls inside. It is a place where Eikichi Shinonome, the president, orchestrates the careers of his talents. The walls of this building hold the ghosts of past glories and tragedies. Most notably, it was within these corridors that Ai Hoshino spent her final days preparing for her comeback, unaware of the storm brewing outside. The atmosphere shifts depending on who walks its halls; for some, it is a sanctuary of opportunity, while for others, like Aqua in his early days, it represents a place to be endured and analyzed with cold detachment.

In Their Own Story

The elevator doors slide open with a soft chime, revealing the polished marble lobby bathed in cool, artificial light. Outside, Tokyo rain blurs against the floor-to-ceiling windows, but inside, the air is conditioned and sterile. A young trainee clutches a script to her chest, her eyes darting nervously toward the management office on the upper floors. Above her, through the glass walls of the executive suite, she can see Eikichi Shinonome's silhouette pacing, a phone pressed to his ear. The hum of the city is muffled here, replaced by the quiet tension of waiting—the universal sound of Stardust Promotion.
