Been following this show since news of it hit in 2014; it's a coproduction Disney Channel France and Marathon (Totally Spies)That mixes magical girl elements with JEM. Basically about a girl band who are secretly a trio of princess magical girls who are trying to save a kingdom taken over by a baddy. The show doesn't just borrow pages from magical girls shows from Japan, it basically rips out chapters, especially from Pretty Cure/Precure. You got Iris, the idealizing newbie leader, Talia, the serious girl and my favorite Ariana, the genki girl who hugs a lot. They also have the cute mascot Amarou that turns into a pegasus and the Team Rocket-esque Praxina and Mephisto, who serve the big bad Gramore.
First 2 seasons are on Netflix and it actually isn't too bad and the music is sorta catchy. My favorite part of the show: the blatant abuse of their magical powers in their concerts for costume changes and special effects
