Haley Belle

Haley Belle is a minor character in the Death Note series. He is one of the twelve FBI agents who comes to Japan to assist L in investigating the Japanese police for the Kira case. He is only referenced in the manga, but he has a minor role in some adaptations.

Plot
Light Yagami controls Raye Penber with the Death Note to get him to write down the names of the other FBI agents working on the Kira case in Japan. Penber does so, and the eleven other FBI agents including Belle die of heart attacks.

L creates a list of the FBI agents along with the order they received the file and the order in which they died. Haley Belle was first to receive the file, and fifth to die.

L later shows Light a list of the FBI agents along with their times of death and the time they received a file. Belle received the file at 15:19 (3:19pm) and died at 15:52 (3:52pm).

2015 television drama
The character is renamed Henneth Belle in the Death Note 2015 television drama. In the third episode, Penber calls Belle to get the files of all the FBI agents, but Belle doesn't have the files and suggests he call the chief instead. Penber asks Belle to get the files from the chief and send them to him, and Belle does so. Belle has an English accent on the phone.

Musical
In Death Note: The Musical, Haley Belle essentially takes the place of Penber. Light finds Haley Belle's name because Belle's fiancé put information about them online, and he uses the Death Note to make Belle kill the other FBI agents by writing down their names. Belle dies by jumping in front of a train, as written by Light in the Death Note.
