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

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, right behind Takada in terms of popularity. In the one-shot chapter set three years after Light's death, it is revealed that she and Rester continue to work with Near.

Although not stated, Lidner seemed to somewhat care for Mello. Although she was ultimately working for Near, she appeared to share more information with Mello than Near was aware of. Also, when Lidner realized that Mello had died inside the burning vehicle, she thought, "Oh no...Mello..."
