Blurb:

In a futuristic world, the once blasphemous idea of robotic implants is starting to change the world. However, a group known as The Brigade uses this discovery for their heinous crimes, often abducting critical patients in hospitals to make them into their half human, half Cyborg pawns. It is up to the Recon Core to save these unwillingly turned people and rehabilitate them to be able to live normal lives despite their modified implants.

Agent Eren Jaeger of Squad 104 had recently lost his adoptive younger sister, Agent Mikasa Ackerman, in an explosion during a mission. Taken by grief and anger for losing the only family he has left, he's more fired and up than ever to take down the Brigade, avenge his sister's death, and prevent more innocent people to be turned into unwilling disposable pawns. But his life became even more complicated when he finds an unconscious Cyborg discarded and left for dead with the serial number L3V1-A1225 and whose instability could end up killing him.

Cyborg JE4N-K407, now known as Agent Jean Kirschtein, is a young man that was saved by the Recon Core three years ago. On the final month of his rehabilitation, he made the decision to be drafted in the Core's 104th Squad because living a "normal" life would be a lie. He keeps telling himself that he wants save those who are taken by the Brigade and take revenge for what they did to him, but one look at the 104th's tactician with those sky blue eyes, hair of spun gold and that brilliant mind, he knew deep inside that he was meant to become his shield.
