Nomura

Nomura (野村) is a character in. She is a member of the mysterious "Tokyo" organization.

Appearance
Nomura appears as an older woman with sharp purple eyes and long purple hair.

Matsuribayashi-hen
Her true motive is to have the old Koizumi faction in Tokyo fall down due to the Great Hinamizawa Disaster and the research project becoming a mess afterwards. She is shown to be a skilled manipulator of emotions, using Takano's grief and acting as though she understands in order to gain her trust and become the new backing up of the research institution.

When the Great Hinamizawa Disaster occurs, Nomura promises Takano that she will be allotted a new research facility elsewhere and that she will be able to research as much as she pleases- however, Takano has her doubts as well and figures that she will probably be disposed of by the SDF one day in the future.

Nomura has been purposely plotting for Takano to make the Great Hinamizawa Disaster happen in order to make the Alphabet Project become questioned and ultimately have the Old Koizumi, Chiba and Okuno faction fall. She is not using her real name with negotiations and has several nicknames that she uses with different people i.e. speaking to the Chief Cabinet Secretary as 'Maizawa', etc.

Although Takano bribed the Mountain Hounds with enough money to have them assist her in carrying out the Great Hinamizawa Disaster, it seems as though Okonogi is in direct contact with Nomura (under the codename 'Cuckoo') and is directly influenced by her as evidence by the 'backup scenario' (involving Takano committing suicide under the pretense of a 'gunfight breaking out') he presents to Takano during Matsuribayashi-hen.

Higurashi Outbreak
Nomura forces the Prime Minister of Japan to give control of the situation in Hinamizawa to the Alphabet Project.

Trivia

 * Given that Nomura is shown using several different names over the course of, it is possible that "Nomura" is not actually her name but an alias that she uses with Takano and the Mountain Houdns.
