L (エル, Eru) is a world-renowned detective who takes on the challenge of catching the mass murderer known as Kira. In his investigation, L becomes suspicious of Light Yagami and makes it his goal to prove that Light is Kira.
L is quite secretive, and only communicates with the world through his assistant, Watari. He never shows his face to the world in person, instead representing himself with a capital letter L drawn in "Old English MT" or "Cloister Black" typeface. It is more likely to be "Cloister Black" as Watari's "W" is different in "Old English MT."
After meeting the Japanese Task Force, he requests that the task force refer to him as "Ryuzaki" as an additional safety measure. The Task Force never learns his true name, and it is revealed in neither the manga nor anime.
L is very intelligent, though his disheveled and languid appearance masks his great powers of deduction and many question his abilities upon viewing him. L tends to second-guess everything he is presented with, and is extremely meticulous and analytical. He is good at deceiving his opponents, and is willing to take drastic measures to solve a case. Some of his tactics are quite bold, such as having death row inmate Lind L. Tailor pose as himself on live TV in order to draw out Kira, while others seem bizarre to those involved, such as handcuffing himself to suspected-Kira, Light Yagami. He is also shown to have a dry sense of humor, and he isn't above making sarcastic remarks to people. Although he tends to be polite, to some (such as Task Force member Shuichi Aizawa), L can seem condescending at times.
Using subterfuge, misinformation, disinformation, and an analytical knowledge of human nature to help lure a suspected murderer into a false sense of security and possibly make him carelessly over-confident, L sometimes gets what he wants through abnormal or possibly criminal channels. Whenever L gives percentages to indicate how much he suspects a person of committing a crime, such as "five percent," he may in fact be over ninety percent convinced of their culpability. Although L tells Light that he is among the least likely suspects with one of the lowest percentages of probability, in reality L is "pretty certain" that Light is Kira. As series writer Tsugumi Ohba said laughing, making light of L's tactics: "The truth is, he's a liar."
At the age of eight,[4] L was found by Watari and taken to the orphanage known as Wammy's House, a home for gifted children. Sometime after, Watari realized that L had incredible intelligence and later assisted him in his cases.[5] L became a detective at a young, unknown age and eventually gained a reputation as the greatest detective in the world whose opinion is highly valued.
