 A designer named <unk> Koshiki steps forward , claiming he developed the Solid State system before committing suicide . Kusanagi dives into his cyberbrain and into Koshiki 's trap , allowing him to hack her cyberbrain . The <unk> reveals that he was spread across several <unk> until a collective consciousness emerged and developed into a Solid State , allowing him to move into the society beyond as the vanishing mediator . Later , Batou tells a recovering Kusanagi that the real <unk> Koshiki used a cybernetic body and built the Solid State after he was hired by Munei . Kusanagi does not reveal that the Puppeteer was a fragment of herself , but Batou already knew from being linked to her during the dive . Batou concludes that the ultimate identity of the Puppeteer will remain unknown and that incident will be written off a scandal .
