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.

The RIS investigates a death that appears to be linked to Killer B, though Keith disagrees. Another body leads them to stake out a high-powered party.

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.

The team members grapple with the attack on one of their own, and the fact that there must be a traitor on the inside. Koku realizes who Canopus is.

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.

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.

Keith sets off in pursuit of Gilbert once more. Koku finds the zeppelin and Minatsuki, but Laica escapes with Yuna in accordance with the prophecy.

The RIS races to the scene, while Keith confronts Gilbert at the old Jaula Blanca facility. Koku fights Laica for his and Yuna's survival.
