Solution:Flux.
Episode Description:
Shu is apprehended by Segai in front of his classmates and is taken to GHQ Isolation Facility Four, where he remains silent about Funeral Parlor. As Segai is taking Shu to the isolation ward, he reveals that Yahiro's younger brother is receiving treatment at the facility due to being a victim of the Apocalypse Virus, for this is the reason for why Yahiro ratted Shu out. However, Segai dismays Shu when mentioning that Gai plans to rescue a mass murderer named Kenji Kido, giving Shu a transmitter, in the shape of a pen, to use when he comes in contact with Gai. Later that night, Gai, disguised as a lawyer, visits Shu to involve him in rescuing Kenji, but Shu rejects assistance. As the facility's alarm suddenly goes off, Tsugumi informs the two that Inori has broken into the facility and plans to rescue Shu herself, ignoring orders. Gai is forced to change his group's plan of action against the GHQ Endlaves when Shu goes to save her. On the way there, after Ayase protects him from harm, Shu encounters Kenji, extracting and using his Void, in the form of a gravity manipulation device, to stop the GHQ Endlaves and rescue Inori. Following the facility's destruction, Shu once again is offered to join Gai and reluctantly accepts, however he keeps Segai's transmitter and does not inform Gai of their exchange.
