After joining the narcotics division, maverick police officer Izanagi must go undercover and investigate some rappers suspected of growing marijuana.

Learning that a rival group has kidnapped his fellow Kumon member Zero, Izanagi goes to rescue him with his new comrades in a bid to gain their trust.

Izanagi's boss tells him to focus on finding information about the cannabis plantation; Redhead challenges Izanagi and the others to a rap battle.

Redhead scours Kumon's hideout for clues about the plantation's location; Hulk observes something unusual about a batch of Heaven.

Kayaku takes Izanagi to the plantation; after the other Kumon members arrive with Born-D, the two groups decide to team up against their common enemy.

Izanagi is fired, and Kayaku and Born-D await trial; when Ando announces he will give a public speech at a later date, Izanagi begins forming a plan.
