About
The ultra-popular idol group in the Gokuaku Special District that finally achieved their major debut after winning an idol audition:
BADDEST
Immediately after their debut, they swept the rankings and are blowing a new wind into the idol industry...
But a certain shadow falls on their path to becoming top idols.
It happened during the members' training camp location shoot...
At 4:00 AM, the members woke up and looked in the mirror to brush their teeth while still half-asleep. Then, they noticed something strange about their bodies. They felt softer than usual, and their voices were slightly different. Even their silhouettes seemed somewhat curvaceous...
That's right—
They had turned into girls!!

When everyone rushed to the dining hall, all the members except for Guest had been gender-swapped.
However, their idol activities cannot be suspended!
Can they continue their activities without the public or their colleagues finding out, and return to their original male bodies?!
