Four hours earlier, the attack begins. It's clear that the attackers are using the North to gain access to the company's systems. They're also using the South to gain entrance to the North's facilities. Aoshima tells the guys that he's not planning to kill anyone. He's just been hired by a company called "forge safety" , which is basically a fancy way of saying "hackery" . He tells them to shut up and leave the North alone. The guys exit the North and go back to the South, where they're supposed to be.
