L 
                                                             (death-note)

                                                                   L
(エル, Eru) is a world-renowned detective who takes on the challenge of catching the serial killer known only as Kira. In his investigation L becomes highly suspicious of Light Yagami, and makes it his goal to prove that Light is Kira.
L is a very slim, tall young man with black hair and dark eyes. One of his most noticeable features is the shadow below each of his eyes, a result of him being an insomniac. L is always shown to be wearing blue jean trousers and a long-sleeved, white shirt. He almost never wears shoes or socks, preferring to go barefoot while even in public. This was shown when he visited Light Yagami's school and was seen barefoot while sitting on a bench, not bothering to wear his shoes until he got up to walk.
