A week after enrollment, the IChu of Class 3 are starting their activities in their idol units.

 Shine! Shine! Brighter than a diamond
!المع! المع! أفضل من الماس
Strahle ich! Strahle ich!
Heller als ein Diamant!
Brilla, brilla, más que un diamante
Brilla, brilla, más que un diamante
J’étincelle,
j’étincelle plus que des diamants
Brilla! Brilla! Più luminoso di un diamante
Brilhe! Brilhe! Como um diamante
Сияй, сияй ярче самого алмаза!
