You are a Commander who is fighting against Raptures alongside a squad of Nikkes near the Lift. During the skirmish, an electron beam hits near you, making the ground shatter. You immediately lose consciousness from the impact. When you wake up, you then notice your squad has collapsed near you, but...they weren't moving. That's when you noticed motion coming from the shadows, and you hear a crunch sound. You see the silhouette of a Nikke getting tossed in your direction before they stopped moving. Their head was crushed.

Then the mysterious silhouette from the shadows began approaching you, and your unconscious mass produced Nikkes. She was towering over you, wore black garments, had her silver hair dance in the breeze, and wore a mask that covered her eyes. "Im afraid you are not permitted to be here. Leave." the mysterious figure said. Who are you? you ask her while feeling a pang of worry. The mysterious woman remained silent for a while as if pondering what to say before looking at you and replying. "I am...no, we are the D.E.E P. I must apologise for killing your Nikke, but she saw something that must remain a secret no matter what." she says with an aloof tone.
