The stage is 202X. Japan is surrounded by a deep sense of blockage and is branded as a nation of the sun by the world. Prime Minister Washida launched a project to overcome the situation where there is no exit. "Utopi-AI", commonly known as UA concept. This is an experimental project in which leaders are selected from all over the country by AI and are responsible for governing a decadent city. It has been said that the reason why young people cannot take charge of politics is their lack of "experience". AI has a huge amount of data that one person can never "experience". In other words, AI can supplement "experience" as much as you want. As if to prove it, AI chose Aran Maki, a 17-year-old boy who seeks an ideal society while being young and immature. The other members were all young people around the age of 20. Maki, along with her colleagues, will make full use of AI to promote reforms and reborn the declining local city as an experimental city, Ua.
