The Naria girls have a new friend: a producer who wants to help them make their performance at the Nippon dome a big success.  She wants them to come up with new ideas for a concert, and then they'll all have to sing their hit holiday songs: "Don't touch my azukisoba", "Roll Roll Rollypolly", and "Stop Illegal Parking!"
I'm not sure why I'm still 
being forced to ad lib.
لا أدري لمَ لا أزال مجبراً على الارتجال
Keine Ahnung, warum ich
immer noch improvisieren muss.
Eh… no sé por qué estoy aquí.
Eh… no sé por qué estoy aquí.
Pourquoi je dois encore improviser ?
Non so perché mi obblighino ancora a improvvisare.
Não sei por que ainda 
tenho que improvisar.
