In the year 3125, humanity has colonized every corner of the Solar System, trapped by a mysterious phenomenon known as 'The Cage.' Technology has become vital for survival, allowing for the terraforming of previously unimaginable environments. However, there have been not only technological advances but also genetic ones, giving rise to new races. Among them are the 'Zeros,' individuals with the ability to dominate different states of matter through the 'Zero Factor.' The corporate regime that governs the solar system fears the power of the Zeros and has relegated them to the status of slaves, weapons, and entertainment. In opposition to this regime, Gaia emerges, a paramilitary group whose goal is to overthrow the tyranny and bring about radical change. When a Gaia unit composed of Zeros disappears while investigating an incident on Neptune, Gaia forms a special squad of rookies to investigate the situation. This team will become embroiled in dark and dangerous events that will challenge their limits and determination.
