She is from the PreCure, a extremely popular magical girl franchise (although rather unknown in the west) which is almost the modern day equivalent to Sailor Moon (Precure is also made by Toei/Bandai), originally created in 2004 and each year since then they have a completely new generation of girls, so the stories and characters are pretty self-contained.
There's over 50 PreCure girls by now in 2019.
