Halle Lidner

Halle Lidner (ハル・リド ナー, Haru Ridonā) is a member of the SPK working with Near to catch Kira.

Appearance
Halle is a tall, slender woman with golden-brown eyes and a fair complexion. She has medium-length blonde hair with choppy, straight-cut bangs, and she usually wears red lipstick. She wears business attire while working for both the SPK and Kiyomi Takada and is considered attractive by many. Her looks combined with her position as Takada's bodyguard cause her to be a popular figure in the media.

In the video game, Halle has blue eyes and slightly darker hair.

Character
Halle is a former Secret Service and CIA agent who 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 nor Mello's side in their competition to defeat Kira and surpass L. Although she ultimately works for Near, she still leaks information to Mello, sometimes at Near's request.

Halle is intelligent, professional and dedicated to the Kira investigation. She cares for both Near and Mello, trusting Mello to the point that she lets him hide in her apartment and speaks up for his actions during the final confrontation.

Like several other members of the SPK, Halle uses an alias throughout the Kira investigation. Death Note 13: How to Read states that she is "an individual thinker" with "first-rate" skills as a bodyguard.

Plot
Some time after Mello's Mafia base explodes, he gets in contact with Halle, who keeps him up to date regarding Near's theories on the Kira investigation.

Near predicts that Mello will come into contact with Halle and has her inform him of his theory about the second L being Kira. He places bugs on Halle and has her install cameras throughout her house. When Mello learns that Near has a photograph of him, he threatens Halle to let him into SPK headquarters. There, Halle convinces him not to shoot Near.

In Japan, Near assigns Halle to go undercover as one of Kiyomi Takada's new bodyguards. Though she works as a diligent handler, her mission is to uncover the connection between Takada and Kira. While at work, she assists Anthony Rester in taking Misa Amane and Kanzo Mogi into custody.

When Matt fires smoke grenades outside of NHN, Halle hands Takada over to Mello and informs Near of the situation. She instructs the other bodyguards to follow Mello's motorcycle, but he slips away from them. When the SPK and Japanese Task Force arrive at the church where Takada is being held, the church is up in flames and Halle realizes that Mello is dead.

During the final confrontation in the Yellow Box warehouse, Halle speculates that Mello had planned for the exposure of the real notebook when he kidnapped Takada, and in doing so, made the final breakthrough in the case.

In the one-shot chapter set three years after the conclusion of the Kira case, it is revealed that she continues to work with Near, Rester, and Gevanni.

TV Drama
The television drama character Shoko Himura is an amalgamation of several characters including Halle Lidner, Naomi Misora, and Mello. Himura's real name is Halle Lidner, and similar to Lidner, she works with both Near and Mello to help stop Kira.
