●The Silver Case

The dispute among the Kanto Big 3 NGO Parties
(Nonprofit civic organizations)
The Diet-governed, market economy-based socialist state of Kanto, its economic activities drastically limited by government regulations, was exhausted and impoverished.
Severe reductions in both corporate taxes and private consumption only exacerbated the weakening of the government. Employing tactics such as exhaustive lobbying and direct communications with citizens, the three factions known as the FSO, TRO, and CCO―previously operating as nonprofit organizations―had finally forced the government to pay attention. Then, in March of 1979, the “direct governance system” was implemented.

This meant the “volunteerization” of everything from collection and separation of garbage to maintaining public order and security. But this caused a new problem to arise. Since the main source of funding for the three respective factions’ operations was political contributions from a wide range of both corporations and private citizens, the feud among the corporations developed into a war between opposing factions.

As time went by, this war gradually shifted into a battle between the FSO and the TRO/CCO alliance. En route to a symposium, TRO/CCO alliance chairman Ginji Nakane was assassinated in front of the TTV Station building. He was stabbed to death with a sharp, metallic tube-like object. The suspected assassin, Kamui Uehara―said to have been sent by the FSO―then went to the secret headquarters of the TRO/CCO alliance located inside TV Tower and murdered 10 top alliance members. Regional Investigation Unit Special Agent Tetsugoro Kusabi arrived at the scene and arrested Uehara. Uehara was thought to have carried out the assassinations alone under contract, but the person or persons who contracted him were never found.

Due to the victims of this attack being elderly, the incident was christened “The Silver Case”. Taking into consideration the possible effects on society, only the name “Kamui Uehara” made it into the mass media.

●“24 Wards” recognized by the government as a Special Administrative Region.

●Kaoru Hachisuka is appointed as the first mayor of the “24 Wards”.

As a means of avoiding unwanted conflict, the primary center of the government and Department of Finance are established around the former TRO, while the Department of the Environment and Department of Investment are run mainly by the former CCO.

However, the Department of Security is organized into a combination of the two factions: the Central Police Department/Heinous Crimes Unit (former TRO) and Public Security Department/Secret Security Unit (former CCO).

●Residents begin moving into the “24 Wards” Special Administrative Region

Residency in the wards – established as a “special tax area” - is put up for public offering to citizens throughout the country. Approximately 80,000 residents are selected. Resident selection criteria are based on education, income, and lack of religious affiliation.

●First “Shelter Kids” Project

TRO/CCO alliance chairman Hachisuka, worried about the decrease in vitality and viability in teenagers, implements the project as a “crisis control capability enhancement measure”, with approximately 1440 subjects, all two-year-old boys. The participants are made eligible for tuition exemption from elementary school through high school.

●Second “Shelter Kids” Project

Differing from the first project, this is a group abduction incident in which approximately 100 two-year-old boys go missing over a period of two years. Fortunately, almost all of the children are recovered unharmed in 1986. Twenty-two percent of them retain impressive vitality and high-level crisis management abilities.

●Establishment of the Heinous Crimes Unit

Shinji Kotobuki acts as ringleader, with four other establishing members: Tetsugoro Kusabi, Kiyoshi Morikawa, Shigeo Ishikawa, and Sawa Kobayakawa.

●“Royal Nine” Tsubaki Syndicate Conflict

This case, in which the HC Unit’s first female investigator Sawa Kobayakawa and Tsubaki Syndicate member Kenta Arai end up killing each other, develops into all-out war between the HC Unit and the Tsubaki Syndicate. The murder of dyed-in-the-wool HC Unit investigator Shigeo Ishikawa at the hands of the Kenta Arai sets Kusabi and Morikawa into full-on revenge mode, after which they go after syndicate head Tsubaki himself. The case is closed once Tsubaki is made to take responsibility.

●“Power Girl”

This is Sumio Kodai’s first case after his assignment to HC Unit 2. A romance between Sumio and a terrorist on the East Side.

●“Still Town”

Kusabi and Morikawa close off and clean up areas that have devolved into slums. The two agents completely wipe out a group of young criminals.


Nakategawa heads an investigation into a series of serial murders of high school girls. The perpetrator of the chain of bizarre crimes turned out to be the high school principal.

●“Gas Kids” Exhaust Fume Serial Murder Case

An industrial truck enters a quiet bedroom town. After several months, a string of elementary school students die under strange circumstances, one after another. Then, the driver of the truck is shot to death with a shotgun. Kusabi and Sumio rush to the scene. The culprit turns himself in. He turns out to be the father of one of the dead school children.


The high school girl serial murders begin again. Kusabi encounters a suspicious figure with a gun.

●“After Kamui” Copycat

The case occurring immediately after “#1 Decoyman”. A series of crimes are committed using the same M.O. as Kamui. Sumio and Hachisuka join together to investigate. A certain national university student arises as a suspect.


In accordance with the growing population, the 24 Wards―the Kanto Government Special Administrative Region is divided into five separate areas.

An economic rift developed among the residents selected from around the country, with 80% having relatively low income and the remaining 20% having much higher income. The most striking conflict and source of resentment between the economic classes was not the difference in income itself, but rather the discord stemming from stark differences in the distribution and dissemination of information between the two groups.

The crime rate began to soar, and various news programs and other news media propagated and inadvertently exacerbated said conflict.

The population hit 100,000. Mayor Hachisuka was about to enter his fifth term.

The central Police Department Heinous Crimes Unit was basically transformed into an organization tasked with promptly eradicating what became known as “transmittable heinous crimes”.
