Keith rejoins the RIS just in time to work a brutal double murder involving “Killer B.” Then an unknown group steals a military vehicle for a rampage.

Kaela battles the hackers as the poison gas release ticks closer. Keith drags Boris on a chase outside the city, pursuing Koku and one of the gang.
Koku and Keith both pay visits to the Royal Library. Afterward, Lily heads to Keith's apartment to discuss her thoughts on the Killer B case.

After confronting Keith on the roof of the hospital, Koku agrees to meet him at a temple the next day. Keith is declared a murder suspect.
Minatsuki gives the OK for the others to attack Koku, but Keith intervenes to protect him. The RIS receives an ultimatum.
Eric implores Keith to return to the RIS, then suspends Lily in an effort to track Keith down. Minatsuki sends Takeru after Koku.
Keith turns himself in and the RIS decides to spend the few remaining hours laying a trap for the suspected head of Market Maker, using Lily as bait.
Koku searches for the zeppelin containing Market Maker and Yuna. Meanwhile, Keith, Eric and Kaela frantically search for Gilbert and Lily.
