Yamataian Imperial Security Agency

The Imperial Security Agency (ISA, 帝国公安局, Teikoku kōan-kyoku), is the principal intelligence and security service of Yamatai. Its main responsibilities are both inside and outside of the country and include foreign intelligence, counter-intelligence, internal and border security, counter-terrorism, internal surveillance, investigating some other types of grave crimes and federal law violations, and guarding the Government of Yamatai. It is headquartered in the Aramaki Daisuke Building, Heian. The director of the ISA since 2015 is Gotō Takahiro.

The ISA was formed in 1976 with the National Intelligence Law. The Imperial Intelligence Agency was merged with the Public Security Unit, the latter originally under the Ministry of Public Safety. The roots of Yamataian domestic security can be found in the Kenpeitai, the military police of the Yamatai Imperial Army during the late 19th century and early 20th century, who were also charged with maintaining public order and security nationwide. A smaller organisation was the Grasscutter Section, a group dedicated to enforcing the public's loyalty to the Empress of Yamatai, and holding loyalties only to the Empress. In the aftermath of Yamatai's defeat in the Endwar, the Grasscutter Section began causing chaos in Heian and were beyond the control of anyone, including the Empress, so in 1948 the Imperial Army forcefully disbanded the Grasscutter Section. During the military rule of Nariakira Okabe, the Kenpeitai was replaced in its domestic duties by a civilian agency, founding the Public Security Detail in 1952 with the goal of hunting down communist agents and spies.

Targeted killing
In the summer of 2006, the ISA 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 Yamatai.

Tactical Section
The Tactical Section of the ISA is a well-armed paramilitary force numbering around 1,000 special forces troops. The ISA is known to operate some light armoured vehicles and helicopters, and works together with the military to enable the deployment of their troops around the world in the support of Yamataian national security interests.

TokuSa Nobushi Unit
Supposedly guarding Yamatai's strategic facilities.

TokuSa Shikomizue Unit
Little is known about the Moon Group's sister unit, the Wind Group, but it is speculated that the unit is authorised to act under the direct control and sanction of Yamatai's top political leadership. It is believed to be used by the Yamataian government for domestic and international covert military operations and strikes.

Public Security Sections
At least nine Public Security Sections exist, covering nine security sectors defined by the ISA. These forces are specially-trained anti-riot paramilitary operators who are also trained and equipped to take down terrorist threats within the nation.

Batou National Prison
Batou National Prison is a high-security prison run by the ISA and used to house extremely dangerous criminals as well as terrorists. Located somewhere in the Northern Islands of Yamatai, BNP is rumoured to be on an offshore platform, underground or even underwater, but details are scarce. The existence of BNP was only revealed to the public in 2018 when a whistleblower sent Akagi Shinbun details about the black site, forcing the government to acknowledge the existence of such a facility in January. The whistleblower's subsequent disappearance is viewed by some as a confirmation that the ISA is hiding more than it seems in the facility.
