In 2038, the Epoch, a time manipulation system that controls the flow of time, begins to fail, threatening to unravel reality itself. Ryoji Tanaka, a skilled technician, is tasked with restoring the system using a prototype device called the Epoch Stabilizer. Alongside his sister, Akira Tanaka, Ryoji journeys to the Tokyo Data Center, where the Epoch's core is located. Despite multiple attempts, the Stabilizer fails, and Ryoji discovers that the system’s collapse is being sabotaged by an unknown force. As time becomes increasingly unstable, Ryoji must uncover the conspiracy behind the sabotage and race against time to prevent disaster.
