Can the Narcotics Control Division save the streets from drugs' invisible threat?
Kai Eto may look like a squeaky clean kid, but the Greater Kanto Narcotics Control Division's new investigator hides a violent alter ego and a dangerous past. With his stoic partner Hal Kurabayashi, Kai is assigned to track down and stop the distribution of Dragon Speed, a dangerous new drug. But Ryugen, the syndicate trafficking the drug, is almost impossible to infiltrate. Add street violence and a jurisdiction war with the Meguro Police, and poor Kai is in for some very long days at the office.`
Shaken up by the revelations about Kai after the Yokohama Ryugen incident, Hal needs some time to sort things out. Then a new case lands on the NCD squad when a mysterious accident leads to an investigation of Black Fall, an up-and-coming rock band, and its troubled lead singer, Saeki Kanzaki.
