Can the Narcotics Control Division save the streets from drugs' invisible threat? R to L (Japanese Style). Hiki and Kajiyama nail a small-time student drug dealer. The student folds like a napkin, and they turn him into an informer. But when things start going wrong, Hiki gets suspicious of their new stoolie and begins to wonder who is really playing whom. 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.
