With Hina joining Libra and a possible traitor lurking within the agency, Ling and the Zeros face a new threat as they dig deeper into the mystery behind Molybdenum.

After bringing down Ise Shou and the Yanagiba-gumi’s operation, Ling and his fellow Libra agents have stopped the spread of the deadly synthetic drug Molybdenum. But troubling questions remain. The military-grade technology behind the drug came from somewhere, and evidence that information about Libra’s own agents was sold on the black market suggests an even greater threat: someone inside the agency may be working against them.

Meanwhile, Hina has escaped her father’s control and found a new home within Libra’s tech support division. Her extraordinary hacking abilities make her a valuable new asset, while the strange evolution of her synesthesia suggests she may possess abilities even she doesn’t fully understand.

With Hina joining their ranks and the mystery surrounding Molybdenum far from resolved, Ling and the agents of Libra must uncover the forces operating in the shadows and determine whether their greatest threat lies outside the agency...or within it.
