Halle Lidner

Halle Bullook aka 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 is a young woman with white-blonde hair, and amber eyes.

Character
Halle 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 one of her relatives who was killed by 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 seemed to somewhat care for Mello, even trusting him to the point that she let him hide in her flat and even showered in his presence while he was armed with a gun. When she arrived at the scene of a fire, she realized that Mello had died inside the burning vehicle, and thought, "Oh no... Mello..."

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

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 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 with Near.
