There is a magical place called the Star World. It is neither in the human world nor in the netherworld, but a mysterious world hidden deep in the void. Only those who understand the magic of music can enter. In the world of stars, music not only makes people happy, but also has the power to change the world. Magicians use musical notes as weapons and melodies as guidance to defeat monsters and heal all things. There are even people who can conquer another world with just one song and make everything listen to him.
