Okay I'm gonna explain the "magic mermaid" transformation scene, go sreach it up for yourself.
They just put them in a bra, tail and small details, (like two earrings for parsley and that...) and they say "oh just put that in." they look like background characters, oh and guess what? THEY STOLE A SOUND EFFECT FROM SAILOR MOON, they also spammed it like they love it, and the music is terrible.. its like a kid show but with blood, they should've did better, and that's my opinion on this "guardian" show.. but if you like it, its fine its your opinion.
