Shen Xizhen's Spirit Entity residing inside her mental landscape. It has been long silent but suddenly became active during the scene at the welfare institute. Lock completed a sentence from Shen Xizhen's fragmented memories. It threatened to control 001 to make the Dark Zone expand again and prevent Shen Xizhen from recovering her lost memories if she does not comply. Lock claims it never intended to become a Commander and insists it and Shen Xizhen know each other from the past.
