Three boy idol trainees all turned into girls for their debut by a crazy Producer.
About
A group of male idol candidates on the verge of disbandment. On a night of despair, drinking the mysterious beverage provided by their producer was the turning point of their fate. Next morning, the faces in the mirror were... "lovely girls" who looked just like them, yet were decisively different. Before they have time to panic, the mad producer kicks down the door and makes a declaration. "From today, you guys are a girls' idol group, DA☆ Now, let's go to the lessons, YO☆" Yu shows a devilish adaptability, while Riku is furious about the cute clothes. And as the leader, Guest is left holding their head in their hands. An unpredictable TS idol life begins now!
