Set in the near-future city of Den City, the story follows Yusaku Fujiki, a stoic high school student who spends his time in the virtual reality space known as 'LINK VRAINS.' In this digital world, users engage in high-speed 'Speed Duels' while riding hoverboards. Yusaku operates under the alias 'Playmaker' to hunt down the Knights of Hanoi, a mysterious hacker group that threatens the stability of the network and holds secrets regarding a traumatic incident from his past. As the series progresses, Yusaku becomes entangled in a larger conflict involving sentient Artificial Intelligences known as Ignis. Alongside his own partner AI, Ai, Yusaku must navigate complex corporate conspiracies, digital warfare, and the ethical implications of AI consciousness.
