Loser is determined to block Kyouma's path until he regains his memories of his role in Easter Island's destruction, and shows that he has incorporated four Numbers into his suit, giving him tremendous power. Their battle is interrupted when the strange sphere reappears and Kyouma touches it and loses consciousness. Kyouma and Salva seem to be reliving their pasts, when Grendel was sent to Isla to protect Central 60 and help Salva put down a revolt. However, Lwai is accidentally caught in the crossfire and is badly injured by one of Salva's war machines, much to his shock. New Tesla learns that the man behind the Isla revolt is Haruka Seameyer, a former student of Dr. Yurizaki. Kyouma and Grendel are tasked with hunting down Seameyer, who recruits many of Yurizaki's students to revolt against New Tesla. In the present, Loser and Ellie travel deeper into the lab, codenamed Adrastea, where he was once a researcher. Kyouma finally realizes he is trapped in an illusion. The sphere then approaches Kyouma, revealing itself to be Seameyer, who also wants Kyouma's memories. Meanwhile, Mira tends to Kyouma's unconscious body when a huge robot attacks.
