Emergency Manual No.34

Emergency Manual No.34 (緊急マニュアル第34, kinkyū manyuaru dai-sanjūyon) is a document shown in Minagoroshi-hen approved for execution by the Prime Minister and the Director General of the Defense Agency. It is the cause of the Great Hinamizawa Disaster.


1. Employment of the Manual

If Hinamizawa Syndrome threatens to spiral out of control, and the official accepts that this is the case, then the Irie Clinic must make the final decision to preserve the secret and prevent its detection by others.

2. Execution of the Manual

The following is an outline of how to execute that final resolution:
  • Terminate all patients above L2.
  • Destroy all evidence inside the Institute.
  • Conceal the fact that this manual was administered
The contents of this manual must be executed by the Institute Director within 48 hours of the incident. If the Director is not available, the Chief Officer must execute it in his place.
The Institute Director may demand support from the Chief Officer in executing this manual. If this manual is expected to be executed, the Chief Officer may issue the preliminary orders.

3. Final Resolution

The final resolution must be executed in the following steps.

4. Disguise the Incident as a Natural Gas Disaster and Quarantine the Area

The quarantine unit must disguise themselves as police officers and isolate the Hinamizawa region from the outside world. The official explanation must be that there is a gas disaster within the village.
The equipment for the operation will be stored at the vacant lot where Yagouchi Quarry used to be. The equipment must undergo routine maintenance.
In the event of external breach or internal escape, if they do not respond to notice of the gas disaster or orders to evacuate, use of firearms is authorized. The approval to use firearms is given by the Chief of the Secrecy Preservation Unit to the Chief of the Traffic Blockade Unit.

5. Shut Down Communications

The Communication Sabotage Unit must ensure that all forms of communication, including radio, have been disabled in the Hinamizawa area. They must take care not to fall under suspicion, and communications must be disrupted for a minimum amount of time.
The facility belonging to the telephone company is inside of the traffic blockade, so any civilians inside may be shot and killed. The chief of the Secrecy Preservation Unit may give permission to use lethal force to the chief of the Communications Sabotage Unit.

6. Assemble the Infected Carriers

The Secrecy Preservation Unit must assemble the infected populace in the Hinamizawa regional disaster shelter. Refer to the enclosed documents for gathering procedures. Upon assembly, the unit must count the number of the infected and confirm that everyone is present.
Be sure not to allow the infected to expose the true nature of the gas disaster.
Additionally, the infected must not be allowed to bring any large personal belongings with them. However, they may take their valuables, including bank books and cash. The infected who refuse to assemble may be shot, but the chief of the Secrecy Preservation Unit must carefully consider the decision to do so.

7. Terminate the Infected

Once they are assembled, the Secrecy Preservation Unit must terminate all of the infected. Before that point, care must be taken to ensure that they are not suspicious of the story of the gas disaster. Be sure that they are treated as humanely as possible.
If any problems occur, the unit has approval to fire their weapons. The Chief of the Secrecy Preservation Unit must also make that decision.
Bodies with gunshot wounds should not be placed together with those that have been poisoned.

8. Concealment of the Institute

The Institute Concealment Unit must collect all of the classified items (refer to the 193 items in the appendix) in the Institute in order to suppress the evidence. Refer to the appendix for more detailed instructions. The research staff at the Institute must assist with this operation. This unit must exercise extreme caution, as they will be handling a number of toxic substances.
Strict quarantine must be maintained of the concealment block. The airproof door must be welded shut, and the underground area must be flooded. The entrance to the area must be welded shut and concealed completely. Furthermore, the concealment block will be completely removed within three years.
The Institute Concealment Unit must eliminate all civilians who would try to approach the Institute. The use of firearms is not permitted, except in emergencies. The Chief of the Secrecy Preservation Unit may give the order to fire.

9. Searching the Village

The Secrecy Preservation Unit must search the whole village for any survivors. Any person who was not present during the assembly must be found. Any survivors found after the termination of the infected may be shot immediately. However, if the survivor is willing to surrender, do not shoot, and instead take them into the custody of the Secrecy Preservation Unit. The Unit must then terminate the captive, using the same method as for the other infected.

10. Post-Mission Transfer to General Forces

Transfer the job to the official disaster recovery team. Make sure not to arouse suspicion.

11. Complete Withdrawal

After the completion of all operations, the Secrecy Protection Unit will retreat from the Hinamizawa area. They must be careful not to be suspected by the disaster recovery team. Furthermore, the Institute will continue to secure the concealment block until complete removal is finished.


  • As Director, Irie is supposed to be the one to execute the manual; however, he supposedly commits suicide, and Takano executes the manual in his stead.
  • Like one of Takano's scrapbooks, this manual is named after her, as the kanji for 3 (三) and 4 (四) make up Takano's first name (Miyo).
