Aiber

Aiber (アイバー Aibā), whose real name is Thierry Morrello, is a professional con-man in the employ of L. Aiber plays the role of Eraldo Coil (エラルド・コイル Erarudo Koiru), one of L's detective aliases, during the investigation of the Yotsuba Group. Aiber uses his initial "A", just like L, when communicating through computers.Aiber doesn't like the idea of guns and using them, but when there after Higuchi he fires a shot at Higuchis head. Its a miss though. In the manga, after L's death, Light Yagami writes Aiber's real name in the Death Note. Aiber dies of liver cancer in a hospital in Paris, France with his family at his bedside. In the anime Aiber suddenly dies in front of his family (probably from a heart attack as only his name was shown to be written in the Death Note). Aiber is voiced by Takuya Kirimoto in the Japanese anime, and David Orth in the English version.

According to Obata, his editor told him that Aiber was a "sarcastic, comic relief" character. Obata said that he wishes that he could have drawn Aiber to be "more comedic." Obata believes that if he drew Aiber and Wedy to look "a little bit more original," Ohba could have included the characters in a larger role in Death Note.

Trivia

 * The fact that his real name is Thierry, and the fact that he died in France with his family both suggest that he is in fact French. The fact that he is also seen as staying near the famous landmark known as the 'Arc de Triomphe' in Paris during his call to the Yotsuba group further strengthens this.But the surname Morrello doesn't exist in France.
