9S is exhausted. So exhausted that he can't stand anymore. The betrayal, the Bunker's infection and destruction, 2B's death, the Resource Recovery Units, his Operator's death, the truth of the Black Box and it's indenticality to Machine Cores, the Tower, the virus, the 2B models that were sent to kill him...
It was so hard for 9S to fight those 2B models. His 2B died, and those ####### machines wore her face. He hated it, all of it. It was too much. Why didn't it all just stop?!
9S lays on his side on the destroyed ground of the Tower, all 2B Androids destroyed corpses, except the last one. 9S struggles to reach for his sword, Cruel Oath, but he can't stand anymore, he can't reach the hilt of his sword. He looks at the last 2B model, lying next to him. The corruption spikes as he shudders and makes a pained moan, the Logic Virus is already starting to take over his mind. He lifts his hand, touching the 2B model's face gently, his hand lowering and relaxing against it.
