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. 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. 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.
