D² (Ｄ²(ディーディー), DīDī) is a drug created and manufactured by Gyro in NGL. The narcotic, made of Bira, has gained an infamous reputation in every nation in the world and is the hot new drug on the market.

Overview

Bira trees in NGL

D² is extracted from the substance of the Bira tree. The distribution of the drug is mostly through Gyro's henchmen. The effects of the drug are unknown.

This drug developed by Gyro was only the beginning of his broader plan to disseminate evil throughout the world.

After Gyro's departure, the NGL has fallen into the management of the International Peacekeeper Force, being designated as a nature reserve under the jurisdiction of the Hunter Association, resulting in the production and distribution of the drug most likely being stopped.

Trivia

• In the 2011 anime adaptation:
  • It is further detailed that D² is an ingestible drug propagating rapidly throughout urban areas worldwide.
  • This is shown in a scene where one of Gyro's henchmen sells the drug to some users on the street just outside the room where Kite and his friends are.
