Description

"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. Together with his stoic partner Hal Kurabayashi, Kai is assigned to track down and stop the distribution of a dangerous new drug--Dragon Speed.
Kai and Hal go undercover as students at the Teito Academy to bust a drug ring working out of the elite private school. With one student dead already, Kai is desperate to solve the case. But with the leaders of the drug ring spiraling out of control and Kai's cover about to be blown, can he break the case before the whole school suffers?"
