At the foot of Mount Helicon, the next Muses are to be chosen between apprentices. But young Mil, Apollo's favorite amongst all apprentices, has other plans : she wants to become more than just a temporary Muse, she wants to become a Myth. Have a fame that transcends this aesthetical world. Have her own constellation. With her friends Coda, Yu and Noamié, she trains every day and wreaks havoc fighting creatures in the mythological world, hoping that one day, they'll be remembered as Myths.
