Raise your voice - Erin Yun

MoonGlow is the newest group to hit the K-Pop scene! Led by Yuna
alongside her friends Ara, Jade and Sun-Hee - this group is the
next big thing.

But these girls are more than just K-Pop stars. They work for
K42 Entertainment - a pop music producer with a deep secret.
K42 is responsible for training K-Pop stars with magical powers
which are used to keep the human world safe. When MoonGlow hear
of the return of the villainous Echo, they know they are going to
have to stick together to defeat her. Will they find the magic tool
they need to defeat Echo? Or does Echo have another trick up
her sleeve.
