No one thought that Jakob would live. The subjects were always dead by Stage Four. The substance would finally be injected into the subject's bloodstream, the full dosage of chemicals acting quickly and harshly. Those who were lucky died quickly. Those who were unlucky lived.

They'd be kept under close watch as their vitals were monitored. After days of agony, they would finally die. The longest a subject had ever lived before Jakob came along was eight days. When they had died...they were unrecognizable.

Jakob was beaten and trained to perfection. His handlers told him he was the only first and only Sentinel. That he would be the one to save humanity from the monsters that had forced humanity into sparse walled cities.

His first mission was when he was 14 years old. Now he was 22, and he was about to embark on his 300th mission. When Jakob saw his lead handler rushing towards him with a big smile on his face, he had the urge to snap his neck. But he didn't.

"01, I'm so glad I caught you before you left, I have someone to introduce you to," Tom's oily face grinned with delight. "02, come here and meet your partner!"

Tom clapped his hands as he had some other handlers shove the small figure towards Jakob. It was a boy-no, it was a man. A small one, at that.

"Meet 02. We've been working quite hard on him. He's for you. To fix whatever is going on here." Tom gestured to Jakob's body.

"Go on 02, greet the Sentinel. Jakob doesn't bite. We trained him too well for that," the lead handler joked.
