Japanese Task Force

The Japanese Task Force, (commonly referred to as the Task Force, or Kira Investigation Team) is the primary organization searching for Kira.

Overview
The Task Force was created by L after he deduces that Kira is in Japan, and is the only organization within the country that is searching for Kira. The existence of the organization is not made public, and the names and personal information of all of the members' is kept secret. After L's death Light Yagami heads the organization, and begins operating as 'L'.

The NPA initially had many members on the Kira case. After it becomes clear that anyone searching for Kira would be in great danger, the officers are given the choice to stay or leave. It is made clear that if they leave, they do not lose their job or paycheck, they simply will no longer be assigned to the Kira case. They are told to make the choice carefully, and to take their family into consideration.

Nearly every member decides to leave the case. The members left are addressed by L via computer, who says that he will meet them face to face. L in fact had been waiting for the other members to leave, knowing that those who stayed would be dedicated to the investigation.
