A week after enrollment, the IChu of Class 3 are starting their activities in their idol units. Amidst all this, Principal Kuma issues them an assignment: If you don't sell 3000 CDs within 3 months, you'll be expelled! Each unit begins to move slowly toward accomplishing this goal, but F∞F just can't seem to get in sync with each other...
 Shine! Shine! Like jewels!
!المع! المع! مثل الجواهر
Ich strahle! Ich strahle! So wie Juwelen!
Brilla, brilla como una joya
Brilla, brilla como una joya
On va scintiller,
scintiller comme des joyaux
Brilla! Brilla! Come dei gioielli
Brilhe! Brilhe! Como pedras preciosas
Сияй, сияй, словно алмаз.
