One day, Yuuki heads out to deliver an item to a client. When Pecorine and the others meet up with him, they discover that the client is Tsumugi, a member of the popular idol group Carmina, and Yuuki is being made to wear a cute outfit at her behest. The group is naturally confused, but there seems to be a reason behind it...
Darn it, Koro-ster!

Esquece isso, Auxilia-koro, caramba!
Так, а ну, быстро забыла об этом!
