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
Lidner is a woman with white-blonde chest length hair and amber eyes.

In the video game, her jaw is less broad, her hair is a darker shade of yellow, and her eyes are blue.

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 aquaintance who was killed by Kyosuke Higuchi at the time when he acted as Kira. She states that she is on neither Near's or 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 had 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 acted 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.
