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.
Yusuke Shinoda is a freelance writer who just got out of the slammer on drug charges, but the NCD's going to keep tabs on him to see if he's really clean, and if not, to see what he'll lead them to. As always, the truth in this drug-fueled intrigue won't be pretty.
