Karin convinces the Japanese government to use Kuwait as bait to lure out Serpent, despite the fact it will destroy that country's economy. Kuniko and Nagiko both watch the manipulation of carbon coefficient. Kunihito intends to resign for the loss of the mimic armor sample, but his superior tells him that Atlas has already pardoned him for this mistake. He is ordered to head for the Moon Palace to meet Mikuni. While Mikuni questions Kunihito on his recent events, Sayoko finds his Atlas rank is classified. She also discovers that his family blade matches the same material and shape as Mikuni's sacred blade. The lord of Atlas, Hiruko, goes hysterical from the thought of having the two blades meet. The government begins its hunt for Serpent. After Serpent takes the bait, Kuniko, with Nagiko's help, locates it originating from one of the islands in the Maldives. Ryoko obtains this information and sends it to America. Kuniko learns that America has dropped thermobaric bombs on the location, erasing Serpent's threat and stabilising the carbon market. Karin discovers it was her peer, Talsian, who created a copy of Medusa for the Maldives, using this incident to teach the original Medusa caution.
