It is the year 2014. Shibuya has separated from Japan and become an independent nation. It is a town of chaos inhabited only by young people. Life necessities such as electricity, water, and food are transported out of Shibuya via pipelines. These pipelines run like a cobweb across the sky, making the young people of Shibuya look like bugs trapped in it. In this city, there are people called "Prayers". They earn money through musical battles. They convert music into electric signals and inject them into brains, destroying each other's minds and bodies.
