KAMITSUBAKI CITY UNDER CONSTRUCTION

Songs are magic. They can change the world and even alter fate.
Seven years ago, a great disaster struck and left human civilization in ruins. Kamitsubaki City, once a cutting-edge academic research metropolis, has been slowly achieving a miraculous recovery by making full use of its advanced technology.
However, beneath the surface of this prosperity, monsters known as "Tesseractor," born from human malice and desire, have begun causing strange incidents throughout the city.
The only ones who can stand against these creatures are five girls known as Witchling.
Their singing voices hold magical power, and they fight the Tesseractor in order to protect the peace of the city.
In a world that has already been broken, the story of these girls who struggle against fate is about to begin.
