Disk and the others manage to use one of the giant Testaments to sneak inside Simeon Headquarters. However, the group are attacked and separated whilst trying to find Eve and Adam. Meanwhile, Adam faces off against Mio, Kuchinashi and Setsuna in the Third Shelter but the trio prove far more powerful than he previously thought.
Adam and the others receive information from a mysterious character called Disk who instructs them to head to Iron Mountain. On the way they encounter a scared young girl called Mio who ends up tagging along. When they finally meet Disk they are surprised to find a young female cyborg rather than the decrepit old man they expected.
