Lawliet, L

エルローライト

Spoiler

L, who also goes by the aliases Hideki Ryuga, Ryuzaki, Eraldo Coil, and Deneuve—the latter two having earned him reputations as the second- and third-best detectives in the world—is quite secretive and interacts with the world solely through his assistant, Watari. He never reveals his face to the public, instead representing himself with a capital L in Cloister Black font. After meeting the Kira investigation team, he requests that the task force refer to him as Ryuzaki for the sake of discretion. The Kira investigation team never learns his true name.
L's disheveled and languid appearance conceals his formidable powers of deduction and insight. He tends to second-guess everything presented to him and is extremely meticulous and analytical. He has several quirks, such as preferring to crouch rather than sit, eating only sweet foods like desserts and fruits, and holding items very delicately. He spent five years in England, during which time he was the champion of the England Junior Cup in tennis.
L suggests that despite eating only sweet foods, he remains underweight because the brain consumes the most calories of any organ in the body. He also states that if he sits normally, his reasoning ability would drop by 40%.
