Akitsukunese Imperial Security Agency

The Imperial Security Agency (帝国公安局), also known as the Public Security Service, is the domestic intelligence and security service of Akitsukuni. Its main responsibilities are within the country and include counter-intelligence, internal and border security, counter-terrorism, and surveillance as well as investigating some other types of grave crimes and national law violations. It is headquartered in the Daisuke Aramaki Building in Heian.

The Director of the ISB since 2015 is Kiichi Goto.

Targeted killing
In the summer of 2006, the ISB was given the legal power to engage in targeted killing, and hunt down and kill terrorism suspects overseas if ordered to do so by the Prime Minister of Akitsukuni.

Border protection
The ISB also guards the land borders of Akitsukuni. They guard the border with Zhouran, the north-eastern border of Chosen and the northern frontier of the New Territories to prevent illegal crossings.

Intimidation of foreign diplomats and journalists
The ISB has also been accused of using psychological techniques to intimidate foreign diplomats and journalists that have gained sensitive information or display subversive attitudes or ideologies, with the intention of making them leave Akitsukuni early. Anonymous sources claim that the techniques used involve having prominent agents follow and watch the targets from a distance, as well as entering targets' houses, moving household items around, replacing items with similar (but slightly different) items, all with the intention of confusing and scaring the target.

TokuSa Wind Group
The ISB operates at least two TokuSa units, which are independent of the Imperial Military and are actually subordinate to the ISB. Little is known about the exact nature of these units' primary directives, but it is speculated that these units are authorised to act under the direct control and sanction of Akitsukuni's top political leadership. The known units are the TokuSa Moon Group, which is officially tasked with protecting Akitsukuni's military and strategic installations, and the TokuSa Wind Group, which is a dedicated counter-terrorism task force which primarily prevents and responds to violent acts in civilian infrastructure and locations. Both units are also available for extended police duties, for paramilitary operations, and for covert operations, both domestically and internationally.

Although the exact number of ISB TokuSa operators is unknown, it is speculated to be around 1,600. There is also speculation that a third TokuSa unit exists for the sole purpose of carrying out domestic and international assassinations.

The secret prison for political prisoners. Who knows what goes on in this high-tech gulag?

Criticism
Some have said the ISB is basically a secret police loyal to the government.
