Tokyo 24th Ward

The Hazard Cast, a surveillance system that foretells accidents and aids sufferers right away, keeps residents of the 24th Ward, a special jurisdiction region constructed in Tokyo Bay, very secure. The algorithm, however, is unable to predict these accidents' precise nature or stop them from occurring. The tragic significance of these restrictions became apparent to Ran Akagi, Kouki Suidou, and Shuuta Aoi—a group of friends known as "RGB" because of the color of their hair—when Suidou's sister Asami perished in a fire at her high school. One year later, Kouki works in the Hazard Cast intervention unit, Ran pursues his dream of becoming a well-known street artist, and Shuuta continues to feel guilty for not saving Asami. Each member of the RGB three gets a surprising phone call after they reunite at a memorial for the school fire victims. The three buddies are asked to pick between two bleak options after being perplexed to hear Asami's voice. The three confront this unpleasant incident head-on, refusing to be constrained by anticipated results. This marks the start of a series of harsh conundrums that they will have to solve in order to safeguard the 24th Ward and its residents.
