Secretive, meticulous and cunning, L's desire to win coupled with his intellect give him the reputation of being the best detective in the world. His disheveled and childish exterior masks his sharp and analytical mind, throwing off his adversaries. Reclusive and paranoid, L solves his cases by communicating with the outside world via his assistant Watari and a computer with voice scrambler. L has a sweet tooth, and can often be found crouching instead of sitting normally while snacking on cakes. He is adept at mind games and much like a child, is willing to do almost anything to win, aided by his mysterious, impassive expression and his monotonous voice, which make him impossible to read.
