Joining forces with Alice, Iska and his team quash the Empire and the Sovereignty's conspiracy and successfully protect Sisbell. After the ordeal, they travel to Alsamira to enjoy their vacation. However, Sisbell has not returned to the palace yet, and asks Unit N07 on vacation to escort her back, offering something they can’t refuse. Meanwhile, Alice gets a gut feeling that Sisbell's new bodyguard might be Iska...

The suspect who attempted the assassination may target Sisbell next, since she hosts an astral spirit with the ability to reenact the past and identify the suspect. Unit N07 goes on high alert and is left with no other option but to hide at a hotel and wait for an audience with Mirabella. However, a large explosion occurs near the hotel. When Sisbell tries to reenact what really happened, someone with the same "shadow" from the reenactment starts to attack her.

Alice is back in the central province and reports to her mother about Sisbell's whereabouts. Sisbell herself also returns to the central province a short time later. However, upon her arrival, there is a surprising encounter.
