04 Forgotten Sand



The Gray Ravens reach Kamui while his infection threshold is still low enough, but not before Roland manages to slip away. Together, they escape the crumbling estate into the desert, and attempt to return to Babylonia, only to find their transport aircraft already destroyed by Roland. To make matters worse, a corrupted bionic sandworm named Vassago suddenly emerges to attack them. It escapes underground before the group can deal the final blow.

The group encounters another unknown signal, which turns out to be Watanabe, the leader of an organization called the Forsaken. Watanabe used to be a Construct of Babylonia before defecting and creating the Forsaken for those who were abandoned by Babylonia during the Great Evacuation. Because of this, the relationship between Babylonia and the Forsaken remains strained even now. Watanabe recognizes Lucia, and Kamui mentions the three of them training together many years ago; Lucia, however, remembers none of it.

Watanabe gives the Commandant a box of mint leaves to “commemorate” their first meeting. This seemingly friendly gesture turns out to be a trap: Watanabe intentionally leads them into a large group of Corrupted and kidnaps Liv while the rest fight off the Corrupted. Furthermore, the scent of the mint leaves attracts Vassago once again. After a challenging battle, the Gray Ravens defeat Vassago.



During the Gray Ravens’ escape from the estate museum, Liv connects her M.I.N.D. to a security robot named Zack.

In Zack’s memory database, Liv discovers a record titled “Operation Grand Retreat” that allows her to glimpse into the past of the estate:

Copperfield, the master of the estate, and his daughter Emma attempt to leave for Babylonia. In the process, Zack saves Emma from the Corrupted and takes her back to Copperfield, but the two must leave Zack and butler robot Leon behind. Emma is reluctant to leave without her machine companions, but Leon reassures her by saying that they will be able to see each other again in Babylonia because their data is already backed up.

After the two leave, Leon takes infected Zack to a static-lock chamber. Copperfield’s research inside the chamber controls Zack’s infection level, leaving his memory data intact enough to be eventually analyzed by Liv in the future.
