A professional con-man, Aiber is hired by L for his skills. He was proven helpful in playing the role of Eraldo Coil in the Yotsuba Arc, and in coaching Misa for her interview with the Yotsuba group. He died from liver cancer on 7 April, 2005. Aiber is also known by his initial "A", just like "L" and other people who have great influence in the organization that hunts down Kira.
Namikawa is the Vice President of Sales. He initially encourages the Yotsuba Kira. After receiving a telephone call from Light he ceases participation and observes the scenario. How to Read describes him as the "most talented" of the board members who has the potential to "make it to the top" without Kira. He has a talent in shogi at the professional 4-dan level. How to Read 13 states that he detests useless subordinates.
Hirokazu Ukita is the most emotional of the Kira investigation team that is lead by L. When Misa Amane has Sakura TV broadcast a message from her as Kira, Ukita rushes to the station to stop the broadcast, without any prompting by the rest of the team. Since Misa has the Shinigami Eyes, she kills him as soon as he approaches the door and is about to shoot. He is voiced by Hidenobu Kiuchi in the Japanese anime and Jeremy From in the English dub. In the film, he is portrayed by Ikuji Nakamura, and appears notably older. Ukita does not die in the film.
Hideki Ide is one of the few police officers who remains with Soichiro during the Kira Investigation. He initially leaves when he disagrees with L's methods. Ide later returns and plays a relatively minor role in the Kira investigative team. He helps coordinate their efforts, and performs actions such as organizing a blockade of police cars to trap Higuchi. Later, after L's death, he rejoins the investigation, though he states that he only did so to be with Aizawa. Ide trusts Light more than any of the other Task Force members, except for Light's father.
Stephen works for Near as part of his investigation team, along with Lidner and Rester, and later plays an important role in stopping Kira. When suspicions arise towards Mikami, Near assigns Gevanni the task of following him, studying his methodic lifestyle, and finding his connections to the Death Note. Before the final showdown with Light at the warehouse, Near has Gevanni steal both the fake and real Death Notes from Mikami, and tampers one of the fake's pages. He also creates another fake, replacing the real one, that is later used as Light's ultimate downfall, and ends up being Near's key to proving Light's identity as Kira. While looking for the SPK members' real names, Mikami views his real name as Stephen Loud through his Shinigami Eyes. In the one-shot chapter set three years after Light's death, while he didn't have any speaking lines and much any involvement in the short story, he did appear in one panel alongside Rester and Lidner. This suggests that he may still be working with them under the new L, Near *Wiki
Birthday: February 18, 1980 Height: 180 cm Weight: 52 kg Blood Type: B Likes: Jacuzzi Dislikes: Insects Halle Lidner, real name Halle Bullook, works for Near as part of his investigation team, along with Gevanni and Rester. She is mentioned to be a former CIA agent. In the manga, Lidner knows Mello and leaks SPK information to Mello; Near is unaware of Lidner's SPK information leaking. When Mello questions her and asks her which side she is on(Near or his), She replies that she is on neither side, and merely helps both of them because they are after Kira. Later on, she calls Mello and tells him about Near's plan(Having Mikami write everyone's name down in the notebook), and he replies "I'm the only one who can do it.". This can be seen as the real push that drove Mello to kidnap Takada and eventually save the lives of both investigation teams. Mikami views her real name, Halle Bullook, with his Shinigami eyes and proceeds to write her name as well as the other SPK members' names into his Death Note, but she remains alive due to the notebook being a fake.
