Dollars

Dollars is an online colorless gang, whose name is derived from "dala dala" (meaning "no use" or "not doing anything"). The users would be "dalas", or Dollars.

The Dollars were originally created by Mikado Ryuugamine as a joke, but later he discovers that the organization grows far beyond his original plan. All of the original founders were frightened of it and deserted the project, except for Mikado. The Dollars continue to grow relentlessly, and Mikado still maintained it until recently, in episode 10, where he used it on Namie Yagiri in the first ever mass-gathering of the Ikebukuro Dollars, on April 16th 2010 in the anime.
