Apparently the protagonist will have a calm personality. I think her last name in Kanji would be 花寺 Flower Temple. And Nodoka ( のどか ) can mean Calm, Tranquility

Cure Fontaine "Fontaine is Fountain in Francais Language" her second last name part "Izumi" it also means fountain in japanese "泉"  Her name Chiyu (ちゆ)  meaning Recovery, Healing.

Cure Sparkle other yellow cure with Sun Power? Her name Hinata meaning Sunny Place. His last name has too many meanings if we turn it into Kanji.
