Japan’s Narcotics Control Department assigns two rookie agents to crack the organization behind Funny Angel (FA), a lethal new drug spreading through the underworld. Haru Kurabayashi goes deep undercover within the mafia faction distributing FA, while his partner, Kai Etou, takes a different route—getting hired at a questionable greenhouse suspected of hiding the drug’s source.

Working separately but chasing the same network, Haru and Kai inch closer to the truth as the operation tightens around them. With their covers—and each other—at risk, every decision becomes a calculated gamble that could unravel the investigation.
