List of Kerberos Saga characters

The Metropolitan Police Defense Division (首都警・警備部, shutokei keibibu, lit. "capital police security division"; "Capital Area Security Police Agency" in English adaptations) is the main armed branch of the Metropolitan Police, tasked with maintaining public order. It maintains an armored combat unit, armored cars, a helicopter unit, and a sniper team. It is directed by Isao Aniya.

The Special Armed Garrison (首都警・特機隊 ~ケルベロス~, shutokei tokki-tai ~keruberosu~, lit. "capital police special equipment unit"; "Special Unit" in English adaptations) is the core combat unit of the Metropolitan Police. Its members wear black-colored Protect Gears, armored powered exoskeletons that distinctively feature a Stahlhelm and a gas mask with glowing red lenses. Kerberos members are primarily armed with MG 42 machine guns (often using the bipod as a makeshift foregrip), although alternative weapons such as the StG 44 and FG 42 are also seen to be issued, with the Mauser C96 as a standard issue sidearm; additional ammunition is stored and dispensed from the Protect Gear's integrated backpack. It is headed by Shirou Tatsumi. Notable members include Koichi Todome, Soichiro Toribe, Midori Washio, Toru Inui, and Kazuki Fuse.

Jin-Roh (人狼, jinrō, lit. "man-wolf"; "Wolf Brigade" in English adaptations) is a secret counterintelligence unit formed inside Kerberos to protect it from threats within the police and government. It is headed by Hajime Handa.

The Metropolitan Police Public Security Division (首都警・公安部, shutokei kōanbu, lit. 'capital police public order division') is the other branch of the Metropolitan Police, specializing in intelligence-gathering and espionage. It has an interservice rivalry with Kerberos. It is directed by Bunmei Muroto.

The Tokyo Metropolitan Self-Police Department (警視庁, Keishichō) is the Self-Police of Tokyo Metropolis or, for works implied to be set before 1954, Tokyo City. Into the late 1940s and the 1950s, they were unable to maintain public order in the face of spiking levels of terrorism and crime, sparking the creation of the Metropolitan Security Police Organization. The Self-Police and the Metropolitan Police share a jurisdiction over Tokyo and have many of the same duties, resulting in an uneasy relationship between them, though they are shown to cooperate with the Public Security Division more than Kerberos.

The Spezial Sturm Gruppe (SSG) is the elite counterterrorist police tactical unit of the Tokyo Metropolitan Self-Police Department. They are largely based on the German Federal Police's GSG 9 but are otherwise analogous to the Special Assault Teams of real Japanese police, and are essentially the Self-Police's version of the Metropolitan Police's Special Armed Garrison. In Kerberos Panzer Cop Act 4, they respond to the Lufthansa Flight 666 hijacking at Tokyo International Airport and are briefly involved in a standoff with Kerberos during a dispute over who will engage the hijackers. They are ultimately assigned to resolve the hijacking, but are beaten to the plane by Kerberos.

The 1st Airborne Brigade of the Japan Ground Self-Defense Force. It is a "Panzer Jäger Unit" (ギア部隊) or "Armored Soldier" (機甲隊員), essentially the military equivalent of the Metropolitan Police's Special Armed Garrison, and is likewise also equipped with Protect Gears; however, they primarily use anti-tank rifles instead of machine guns. It is led by Tetsurō Kai.

• Tetsurō Kai (甲斐哲朗)

Appearances: Kerberos Panzer Cop - Part II (Act 5 and Act 8)

The commanding officer of the 1st Airborne Brigade. He infiltrates Kerberos as a trainee and, impressed by Midori, invites her to a JGSDF public exhibition held at Mount Fuji. When Midori goes there with fellow instructor Hachiro Tohbe, they see Tetsurō Kai presenting JGSDF Protect Gear. Later, Kai leads the 1st Airborne Brigade against Kerberos during the Kerberos Uprising.

The Sect (セクト, sekuto) is a left-wing terrorist group that emerged from mergers of other anti-government and leftist movements, especially after the Metropolitan Police and Kerberos began cracking down on such groups. The Sect relies on the Tokyo sewers to transport and store firearms and explosives. Notably, young girls wearing red clothing, nicknamed Little Red Riding Hoods (赤ずきん, Akazukin), are used by the Sect's Division Jacobson (ヤコブソン機関) to smuggle materiel, most commonly bombs, using their non-threatening appearances to smuggle without drawing suspicion.

• Nanami Agawa (阿川七生)

Aliases: Kurzhaar (Short Hairs)

Cast: Eri Sendai

Appearances: Jin-Roh

An adolescent girl used as a Little Red Riding Hood by the Sect. When confronted by Kerberos member Kazuki Fuse while attempting to flee in the sewers, Nanami detonated the bomb she was carrying instead of surrendering or allowing other Kerberos members to execute her, killing herself and causing a power outage during a riot. A character similar to Nanami, but not specifically her, appears in Kerberos Panzer Cop Act 2.

• Kei Amemiya (雨宮圭)

Appearances: Jin-Roh

Cast: Sumi Mutoh

A 17–18-year-old[1] girl who originally worked as a Little Red Riding Hood until she was caught by the Public Security Division, who proceeded to use her to entrap a Kerberos member—Kazuki Fuse, with whom she developed a friendship—and ruin the unit's reputation. Fuse learns of the plan and rescues Kei from Public Security with assistance from Jin-Roh, but is ultimately forced to kill her to protect her from being pursued by Public Security forever.

• Foxy Croquette O-Gin

Appearances: The Red Spectacles, Kerberos & Tachiguishi, Tachiguishi-Retsuden, Onna-Tachiguishi Retsuden

Cast: Mitsuhisa Ishikawa, Mako Hyōdō

A Little Red Riding Hood courier until she was caught by Kerberos. Brought to the Public Security Division, she was used as a mole by Bunmei Muroto. She was a tachiguishi from 1946 to approximately 1960. She appears in The Red Spectacles as a silent young lady who leads Koichi Todome through Tokyo; the film's trailer introduces her as an allegory for fate. After the National Diet Building incident, Foxy Croquette left Tokyo and reappeared in the West Bank as a guerrilla known as "AK Ginko".

• Kusaba (草場)

Appearances: Kerberos Panzer Cop (Act 2)

A saboteur who infiltrates the Metropolitan Police to sabotage Kerberos's new Fa-666 "Jagdhund" attack helicopter.

The Four Seasons League (四季協会, shiki kyokai) is a communist terrorist group. A splinter group of the Sect, it was formed after the Sect's leaders made a compromise with the government to disassociate with its most extreme and violent members. Its background and modus operandi resemble those of the real-life Japanese Red Army.

• Kazuya Fujiwara (藤原 和也)

Appearances: Kerberos Panzer Cop - Part I

The 28-year-old leader of the Four Seasons League. He hijacks Lufthansa Flight 666 at Tokyo International Airport, apparently with the intent of facing off with Kerberos, and sends another group to attack the German Embassy as a diversion. After a battle with Kerberos members Koichi Todome, Midori Washio, and Soichiro Toribe aboard Flight 666 leads to it crash-landing on Showa Island, Fujiwara survives, but is shot and killed by Midori before he can be apprehended by the Self-Police.

The 808th Propagandakompanie (立ち食い, Dai 808 Senden Chutai) is a unit of the Wehrmacht during World War II, deployed on the Eastern Front.

• Cpt. Maki Stauffenberg (マキ・シュタウフェンヴェルク大尉)

Appearances: Kerberos Panzer Jäger

Cast: Yoshiko Sakakibara

The leader of the Wehrmacht's 808th German Propaganda Company (808th Propagandakompanie, 第808宣伝中隊). He leaves the Warsaw station to deliver Protect Gear parts to the 101st Panzer Company fighting the Soviet Army at the Battle of Stalingrad.
