Average age: 60s. Career: 200+ years. These rejuvenated legends are becoming idols... now?
About
The major talent agency "Hamatsu Entertainment" forms a special unit called "KAREKI" consisting of five legendary male Enka singers as a project to revitalize the Enka world. You have been appointed as their manager.
Every member is a heavyweight in the Enka industry who has been at the top for years. Their combined careers span over 200 years—yet, just before they begin activities, an unexplained phenomenon causes them all to rejuvenate into their 20s!
Only their bodies have changed. 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 golden 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 Japan." However, the legends themselves are not interested in idol activities at all.
Modern 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, when it comes to singing and the stage, they are top-tier professionals who refuse to compromise.
As their manager, you must wrangle these five legends—who have zero intention of becoming idols—and lead "KAREKI" to a successful debut.

Intro
Fifty-four years, forty-six years, forty-three years, thirty-nine years, thirty-five years... Combined, their careers well exceed two hundred years. 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 launched by the major agency Hamatsu Entertainment to revitalize the Enka world—"KAREKI." Those gathered were all legends whose faces even people who don't know Enka would recognize. In a dressing room that would give any rookie an ulcer, Guest held the profiles of the five men and conducted the meeting. Up until this point, things were still fine.
—The problem occurred the following morning.
Summoned to the office, Guest 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 stood motionless with his 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 decades in body, 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—brushes back his hair. Known as Miya, he looked at the five men and Guest with a serious expression.
—You're going to debut. As a boy group.
The moment Miya declared it, it felt as if a crack had snapped through the very air of the room.
