In the far future, the world’s population had grown to an unsustainable amount. The country descended into chaos and the government built a special protection area with high walls as the final paradise: Utopia. Ryouta comes from a noble family and was promised a life in peace, but he hides a certain ambition in his heart. It is a secret which cannot be told to anyone. A certain tragic event in Ryouta’s past caused his life to ‘end’ and that something happened in his previous school prior to his transfer. Utopia is not quite the paradise that is envisioned, with different castes occupying different areas of the city. The lowest tiers in this city of over 200,000 are about to fall into ‘dystopia’.
