From the Warlord's Empire IV.Kojo battles the Nalakuvera and Sayaka joins the fray. When his familiar drives the Nalakuvera into the ground, it causes an earthquake and the two fall through a fissure to a lower level of the now leaking and unstable float. Asagi works furiously at deciphering the control system for the Nalakuvera. Yukina discovers Gardos' secret — the hold is filled with manufactured Nalakuvera. Gardos appears and fights her. She severs his arm but is prevented from defeating him by the sudden appearance of two more terrorists bearing the unconscious Nagisa and Asagi. Their situation underground bleakens and Sayaka, spurred by Vatler's earlier, offers herself to Kojo, gaining him control of second familiar. Gardos takes the master Nalakuvera and leads the rest into the fight. Initially the ancient weapons seem indestructible but Yukina destroys them all using a special command secretly created by Asagi after decoding their control system.
