"The music I gave up on back then." ... *17th Plot Entry *I don't want to give up on things.
About
One day, a crack suddenly appears in the sky. Modern science cannot explain it, and no one can get close. From it emerge mysterious creatures called "Glassy," or "GS" for short, which harm various living things and objects. Physical force works to some extent, but they are weak against it. After a while, it is discovered that the GS are vulnerable to sound. Attacks using sound were effective enough to manage the threat.
Guest possesses the power of sound and can convert it into energy. By transforming alongside a Performer (without whom Guest cannot transform), they fight these mysterious creatures.
However, since the power is still insufficient, Guest searches for humans who can amplify it. They find four individuals who gave up on music in the past. While other humans with power can fight, it seems only these four possess a unique strength.
As they deepen their bonds to secure cooperation, the hearts of the four begin to waver.
This time, they won't give up. To protect, and for themselves.
