A tornado hits the Gourmet Festival, and Kaba and many others become victims when a decision is made by RGB. Someone going by the name of Carneades has hacked into the 24th Ward network and left a mysterious message. The trio have no idea who it might be. Meanwhile in the old Shantytown, a highly addictive drug called "D" has become popular, and crime is on the rise. Shuta hears that Kaba's daughter Kozue has been hanging out in this dangerous part of town at night and follows her.

A bomb has been planted on a cruise ship, but RGB are presented with a trolley dilemma again. They have to choose between saving the lives of the VIPs on the ship or the suspected terrorists. Koki insists that they should shoot the suspects to save the targets of the terrorist attack, but Ran has a Vision, where he sees that the real culprit is Kunai, a member of DoRed. Without telling Shuta and Koki, Ran investigates the motive behind Kunai's terrorist attack. What will be the outcome of this trolley dilemma?

Tsuzuragawa is in a coma in the hospital after being saved by Shuta. While tensions grow between DoRed and SARG, Ran investigates what Tsuzuragawa was up to at Cornucopia. Ran meets with his mentor 0th, and hears about his new plan. Meanwhile, during the commotion in Shantytown, Shuta is unsure what to do. At that moment, he sees Kozue being pursued by SARG and goes after them.
