Genius investigator Keith Flick rejoins the royal police force just as serial killer "B" emerges. Mysterious youth Koku may be an ally, or a target.
Koku is approached by Kirisame, a figure from his childhood who he thought was dead. He asks Koku to join him in his fight for a new world order.
Kirisame's subordinates force Koku into carrying out an act of violence against a senator. Then Koku breaks into the royal palace.
The royal palace refuses to fully cooperate with the RIS investigation. Lily and Koku head out to get more information on Keith's disappearance.
Keith's friends narrow down possible locations where he's being held, but with Keith already starting to hallucinate from hunger, time is running out.
Koku, Izanami and Yuna have to fight off an ambush from Kirisame's subordinates. Lily gets pulled over while driving with the king in her car.
With the RIS continuing their pursuit of Killer B, Koku goes into hiding, but Kirisame seeks him out for a final confrontation.
