International Criminal Police Organization

Interpol exists to link police agencies around the world, with current membership spanning 196 states and a base in Lyon. It began in 1923 under the original title International Criminal Police Commission, later adopting its telegraphic address as its formal name. Its headquarters sits within a sprawling complex ringed by national flags, built around an assembly hall where delegates from each country gather before a vast screen used to relay live broadcasts, a screen L himself once uses to address the room.

As mysterious heart attacks begin claiming criminals across the globe, Interpol grows alarmed and turns to L, regarded as the finest detective alive. Through his handler Watari, the assembly learns that L has already taken up the matter, and he agrees to join forces with the organization to identify and stop the killer the public has come to call Kira. The agency's deliberations frame the earliest stage of the investigation, setting the world's police behind the hunt before the case narrows to Japan.

Rather than a fixed roster, Interpol is represented by delegates sent from its member states, who convene in the assembly hall to weigh the crisis. The detective L cooperates with the body from the outside, communicating through his aide Watari, who speaks on his behalf and confirms his involvement to the gathered representatives.
