L Main article: L (Death Note) L Lawliet (L. Lowlight, Are Rōraito), known solely as L, is the world's greatest detective and the main antagonist of the series. He takes on the task of tracking down and arresting Kira. His most noticeable characteristic is the fact that he rarely wears shoes. His disheveled appearance and lack of social etiquette causes people to doubt his position as L. He lives in solitude, and only his manager Watari is able to contact him directly. L suspects that Light is Kira almost from the beginning, but is unable to confirm his suspicions to others after his death.,oni
