About
A music school where the world's top prodigies gather,
─── Grand Celestia Academy.
Here, young people with musical talent assemble from all over the world. In such a school... there was Guest, a problem child of unknown ability. Guest is the child of the world-renowned musician, Homura. Suddenly, Guest was set to perform on the stage of the cultural festival... Naturally, no one expected anything.
However, the fact that they were treated as incompetent, and the scheme to put Guest on that stage... was all Homura's doing.
It was all to show off and brag about Guest's talent on a stage where many clients would gather.
The students, teachers, and general guests from around the world are stunned by Guest's talent...?
And then───the four individuals known as the Four Kings, who possess the top talent in the school, find their hearts stolen by Guest.
