Noiseman Sound Insect

In a world of music and musical plants, a mad scientist is experimenting with the seeds of those plants to create a child, Noiseman. After giving Noiseman a potion to grow faster the scientist couldn't control him anymore and accidentally split his body into a ghost and a crystal with a machine of his. Noiseman is now in control of the whole city, brainwashing people to capture those ghosts and telling the people that the music fruit is forbidden. Tobio who also was brainwashed got hit by a music fruit and remembered the past, where everyone would enjoy the music. He tries to convince Noiseman that his doing is wrong and that he should return the captured ghosts to their crystals but without success. Now the underground people are trying their best to help the ghosts with the help of Tobio's childhood friend.
