My daughter is trying to find a series she watched on Netflix in 2017 or 2018. We are in the USA.
There are 6 main characters, three heroes and three villains, all girls. They are normal girls until they find magical rings and get special powers. She doesn't remember what the powers are, or if their clothes transform, but they stay human.
The characters are teenagers, and at least one of the heroes has relatively long, purple hair.
The villains are always trying to steal the rings from the heroes.
The setting is contemporary as far as she remembers. The villains and heroes at least know of each other, but she's not sure if any of it takes place at school.
She says the animation style is similar to anime, though it may be western animation.
I know this isn't a lot to go on, but she's really upset she can't find it.
