At a geisha house, the female androids have gone out of control. They have taken hostage two members of a foreign body, the Minister of Foreign Affairs, the Minister's secretary, and the head of the Minister's Support Association.

The situation is complicated by a feud over authority between the police and the military. Section 9 Chief Aramaki lends a helping hand and brings in his unit to resolve the crisis.

At a press conference, the Superintendent-General makes himself a prime target for the Laughing Man's threat. Section 9 has gathered enough evidence to arrest Nanao=A, but before they can, he is able to release a modular, delayed-action virus. The virus seems to only affect those on the security detail that is guarding Superintendent-General Daidō. However, Section 9 will not know who on the security team has been taken over by the virus until the symptoms begin to manifest. By that time, it may be too late.

A high-level hacking has occured at the Ministry of Health, Labour and Welfare. Section 9 has traced the source of the hack job back to a vocational aid center located high in the mountains.

The hack was done by someone very skilled since it only took two hours to crack the MHLW's ultra-secure barriers. The odd thing is that the MHLW has not filed a formal complaint about the incident. Togusa is sent undercover to discover what is going on at the aid center.
