Studio Comet
The anime's production was first green-lighted in 2008 and was announced during the 2009 Tokyo Toy Forum on 14 January 2009 to coincide with the franchise's release. Sanrio first contacted Studio Comet if they can make another anime based on their characters, as Onegai My Melody Kirara★ was approaching its conclusion. The studio agreed to do an animated adaptation of the Jewelpet toy line.
