User blog:CureHibiki/Go! Princess Pretty Cure Power Up Spoiler!

This was found on Precure Live Journal so the italics means what the user on Live Journal said:

"The Pretty Cure will have different Mode Elegant, here's the list: Cure Flora: Mode Elegant Rose, Lily, Sakura (cherry) and Primavera. Cure Mermaid: Mode Elegant Ice, Bubble and Sango (coral). Cure Twinkle: Elegant Mode Luna (moon), Shooting Star and Ginga (galaxy). Cure Scarlett: Mode Elegant Sun, Phoenix and Hanabi (fireworks). The Scarlett's attack is called "Scarlett Flame" and the group attack "Royal Majesty." Source: 【※ 超絶 ネ タ バ レ 注意!】 Go! プ リ ン セ ス プ リ キ ュ ア プ リ ン セ ス パ フ ュ ー ム 一部 ネ タ バ レ 音 声 紹 介 (a video on youtube)"

And so it seems, Cure Scarlet is real, not made up. Can't wait to see her later on in the series.
