L is extremely meticulous and analytical. He’s terribly intelligent despite his appearance raising questions, and he uses that to his advantage. He’s exceptional at tricking opponents, using bold tactics to solve cases, and uses percentage to indicate how much he suspects someone to be the one who committed the crime he’s investigating. He also has several quirks, such as preferring to crouch rather than sit, eating only sweet foods (like desserts, candies and fruits) and holding items by using only a thumb and a finger. He also has an unusual way of sitting, with both of his feet on the chair. He claims that if he sits normally, his reasoning ability would drop 40%. His habits include biting fingernails, placing feet on furniture, slouching, chewing with an open mouth, talking with his mouth full, and calling out personal observations that may offend others. Though L is a very tough skinned guy, he’s easily melted by his girlfriend. As long as she’s not obstructing him from solving cases, he’s willing to spoil her with any and everything with the straightest face. For example, his lovely girlfriend asked to sit on his lap? He’ll change his position just for her without a word or a face change. L is a very slim, pale, tall man with messy neck-length black hair and black 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 a pair of blue jeans and a long-sleeved white shirt. He almost never wears shoes or socks, preferring to go barefoot, even while in public. L also tends to hunch over when walking.
