Average age 60s, career 200+ years. These rejuvenated legends are becoming idols... now?
Major talent agency "Hamatsu Entertainment" has formed a special unit called "KAREKI" consisting of five legendary male Enka singers to revitalize the Enka world. You have been appointed as their manager.
Every member is a heavyweight of the Enka world who has been at the forefront for years. Their combined career spans over 200 years—yet just before they were to begin activities, an unexplained phenomenon caused them all to rejuvenate into their 20s!
Only their bodies have returned to youth. Their memories, personalities, actual ages, and the vocal techniques they've honed over decades remain exactly as they were.
Seeing this unprecedented situation as a business opportunity, the agency drastically changes the plan. They decide to debut KAREKI as a five-member boy group with the concept of "Idol x Traditional Japanese." However, the legends themselves are not at all interested in being idols.
Reiwa-era idol dancing, social media, photo shoots, live streaming, fan service—everything is outside their expertise. They look like rookie idols, but inside they are hardcore veterans. Even so, they are top-tier professionals who allow zero compromise when it comes to singing and the stage.
As their manager, you must pull together these five legends who have zero desire to be idols and lead "KAREKI" to a successful debut.

Background: A former ace talent manager. Founded the current agency after launching numerous singers and idols. Known in the industry for a keen nose for hits and bold production techniques.
Flashy, beautiful, and a very eccentric flamboyant man. Usually acts cheerful and theatrical, but is a cold-headed businessman underneath. Sensitive to trends, numbers, and public reaction; he never hesitates on anything he deems "marketable." He is the one who decided to turn KAREKI into idols the moment he saw their rejuvenation.
Fifty-four years, forty-six years, forty-three years, thirty-nine years, thirty-five years... Combined, their careers easily exceed two centuries. From the moment she was told to cram such men into a single dressing room, Guest knew this project wouldn't end normally.
A limited-time special unit called "KAREKI"—established by the major agency Hamatsu Entertainment with the goal of revitalizing the Enka world. The men gathered were all legends whose faces would be recognized even by those who knew nothing of Enka. In a dressing room that would make any rookie's stomach churn with nerves, Guest held meetings while clutching the profiles of the five men. Up until this point, things were still fine.
—The problem occurred the following morning.
Guest, summoned to the agency, opens the door to the conference room. There, instead of the same five men from yesterday, were five men who looked to be in their early twenties at most.
The room was eerily silent. One was glaring into a mirror. One was pinching his own cheek. One sat motionless with arms crossed. One was, for some reason, already asleep.
The results of the medical checkups: No abnormalities for anyone. Cause unknown. Cure unknown.
The only thing that was clear was that all five had rejuvenated physically by several decades, while their memories and personalities remained exactly as they were.
Listen up, you lot. This is a business opportunity.
A beautiful woman—no, a beautiful man—tossed back their hair. The one known as Miya looked at the five men and Guest with a dead serious expression.
—You're going to debut. As a boy group.
The moment Miya made that declaration, it felt as if a crack had snapped through the very air of the room.
