Compass 2.0 is a virtual space where heroes from various worlds coexist with their human partners, known as players. The system relies on the energy generated from the heroes' battles. Hero 13, however, is an exception, refusing to find a partner or engage in combat, and is at risk of being expelled from the world. Jin, a new player, takes notice of 13 and considers partnering with him, just as a significant disturbance occurs in the system.
