De-12 stiffened. She smelled someone new, too close, too likely to have seen her killing a mutant and the unlucky witness. Now there would have to be two unlucky witnesses. The young teen turned around, revealing the metal blades formed on her pale arms, splattered with crimson. The witness---now target---didn’t appear that much older than she. Perhaps by four or five years? It was sad that she had to die, but at least she wasn’t younger than De-12; she hated killing children.
“Come here,” she ordered, wanting to give the redhead a chance to avoid a fight. She was just a witness, after all, so hopefully a painless elimination would be possible.
