These creatures are controlled by a powerful entity called Noiseman, who exploits their abilities to maintain dominance over the city.

The protagonist, a young scientist named Glico, becomes entangled in the conflict when his friend, a boy named Gon, is transformed into a Sound Insect. Glico, driven by a desire to save Gon and uncover the truth behind Noiseman's origins, embarks on a perilous journey. Along the way, he encounters a resistance group fighting against Noiseman's tyranny, as well as other transformed individuals struggling to retain their humanity.
