Mari Sakuragi's family owns and operates the okonomiyaki restaurant in the Takara Shopping street. However, ever since the newly constructed Takara Mall was built, their business has been tough. The 24th Ward Gourmet Festival is just around the corner, and Mari wants to talk to RGB for some advise. However, the RGB boys have their minds already preoccupied with something else.

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?

Thanks to the KANAE system which has been in use for two months, the arrest rate has been going up. After Kunai's terrorist attack, Ran is now wanted as a material witness. Koki has been transferred to the department in SARG that operates the KANAE system. Meanwhile, Shuta has had a falling-out with Koki and Ran. His father Rui has gone to Paris to study, so he has been busy taking care of the Aoi Bakery. While he is struggling to bake the Golden Sunrise bread which is a specialty of the bakery, he receives an email from Kozue.
