Specifically, it's Cure Peach from the fifth season/fourth incarnation of Pretty Cure, called Fresh Pretty Cure (http://en.wikipedia.org/wiki/Fresh_Pretty_Cure!). It's part of the Sunday superhero set; Battle Spirits is on at 7am, then Shinkenger, then Double, then Fresh PreCure.

I don't watch it myself, but a bunch of the people I catch toku with do watch it, so I know a little about it from when they continue to chat as it airs when I've already turned KeyHole/Freshverse off.
