"We are rats thrown into the underground city, we are cockroaches who are trampled to death at will. The place where we live has no light, no sun, no flowers, and no color. They have taken away the pen in our hands and the piano at our fingertips. They will also take away the remaining land under our feet."
"... If we can go to Xavier City, we can transform into butterflies, and we can live under the sun, right?"
"Can we be free?"
"But why is everything outside the world white?"
Concept: love and hate, crime and punishment.
