Department of Internal Affairs

The Department of Internal Affairs keeps an eye on, well, the PPC's internal affairs. After the Reorganisation, the DIS's responsibilities were split into three departments; the DIA, the DES and the DIO. The DIA, given to the Tiger Lily, was put in charge of the actual policing of the agents. They are known to keep watch on agents who are a little too trigger-happy (Selene Windflower, for example), and are deployed to round up agents that have gone flamethower-crazy. They are also charged with arresting and detaining agents who have been marked as needing disciplinary action but who have not yet been assigned any particular disciplinary route. As shown in the original DIA stories, they are also deployed to rescue agents in the field when missions go awry. The Tiger Lily runs the overall department, while the Yertis runs its New Caledonia division. The Blba Tree acts as the DIA's archivist, though it isn't known how long it has held this position.

In HQ, the DIA is made up of three divisions: Patrol, which polices HQ; Special Response, which handles special operations and agent rescue/assistance; and Administration, who are the secretaries, dispatchers and clerks of the DIA, keeping the department running and monitoring security in and around HQ. The Tiger Lily, on top of being overall head of the DIA, directly oversees the Administration Division, while her lieutenants - Dúros Black and Basilico Andretti respectively - head Special Response and Patrol. This state of affairs came about in the aftermath of the Black Cats' invasion, in which the DIA found itself largely ineffective and took heavy losses in the fall of DIA Central; to better protect the PPC, the DIA was reorganised and faced several reforms, including expansions of Central, changes in training standards and recruitment drives. The organisation of the pre-invasion DIA is not entirely known aside from the fact Agent Black still seemed to be in a similar role to his current one.

In emergencies, they have been known to step in to combat invasions, and to make arrests of intruders. DIA agents (sometimes referred to as "officers") are easily noticeable by the fact that they do not wear flashpatches. Prior to the Black Cats' invasion, sunglasses were part of the uniform (as shown here), but it isn't known if this is still the case.
