Halle Lidner

Halle Lidner (ハル・リド ナー, Haru Ridonā) is a member of the SPK. Like the other members of the SPK, she works under a false name since Kira needs to know a person's real name and face before he can kill them.

Appearance
Halle Lidner is a tall, slender woman with a fair complexion and golden hair worn in a medium-length cut. Halle's bangs are choppy, going straight across her forehead, and they reach her eyelids. Her eyes are golden-brown.

Halle's appearance is a bit different in the video game, which shows her with slightly darker hair, blue eyes, and a jaw less broad than in the anime and manga.

Character
Halle Lidner is a former Secret Service and CIA agent who works for Near as part of the SPK, and is the only female member of the organization. She joined the SPK to avenge a close acquaintance who was killed by Kyosuke Higuchi at the time when he acted as Kira. She states that she is on neither Near's nor Mello's side in the competition to capture Kira. Although she ultimately works for Near, she still leaks information to Mello, sometimes at Near's request.

Halle cares for Mello, even trusting him to the point that she lets him hide in her flat. When she arrives at the scene of a fire, she is concerned when she realizes that Mello has died inside the burning vehicle.

Death Note 13: How to Read states that Halle is "an individual thinker" with "first-rate" skills as a bodyguard.

Plot
Halle was chosen over Stephen Gevanni to infiltrate the bodyguard unit that protects Kiyomi Takada, with the purpose to get more information about Kira through her.

In order to attain Takada's trust, Lidner acts out the role of a diligent handler while covertly trying to uncover the connection between Takada and Kira. Her position as a bodyguard of Takada, as well as her beauty, made of her a very popular figure in the media, right behind Takada. In the one-shot chapter set three years after Light's death, it is revealed that she continues to work for Near.

Drama
Halle is undercover for most of the series as Shoko Himura (村章子, Himura Shouko) with the NPA. The character also shares some traits with Naomi Misora, such as being a former FBI agent and having worked with L in the past.

Himura appears to join the Task Force under Soichiro Yagami along the other NPA members, but she had in fact infiltrated the NPA as a cover and was already working with L from the start. L and Himura had worked together in the past and he trusts her. She is very quiet and reserved with the Task Force in the beginning. The alias she is given as part of the Task Force is Taeko Makimura (牧村妙子, Makimura Taeko).

After L's death, when Near's taken over the investigation, she apparently defects and kidnaps Sayu Yagami. But this is in fact part of Near/Mello's plans.

Light controls her with the Death Note. After returning the Death Note to Light, she kills herself in a suicide explosion in an attempt to also kill Near/Mello.

Himura is portrayed by Megumi Seki (関めぐみ, Seki Megumi) in the drama.
