an argument for aroace L Lawliet

It’s true that this doesn’t come from primary canon (manga & anime) but from what I would consider more periphery sources, which are the only places we actually get a look into L’s thought processes on anything other than the Kira case & solving it. So you could also argue the contrary based on what you consider canon. Or, you could argue about how honest L’s being here. It’s not 100% proof, but, I still find these two quotes very interesting. It’s much more straightforward statements about being aspec than you usually get from a character in, like, any media ever…

The Monster Speech (Relight)

There are many types of monsters in this world. Monsters who will not show themselves and who cause trouble, monsters who abduct children, monsters who devour dreams, monsters who suck blood, and monsters who always tell lies.
Lying monsters are a real nuisance. They are much more cunning than other monsters. They pose as humans, even though they have no understanding of the human heart. They eat even though they’ve never experienced hunger. They study, even though they have no interest in academics. They seek friendship, even though they do not know how to love.
If I were to encounter such a monster, I would likely be eaten by it; because in truth, I am that monster.

Exchange from L: Change the WorLd novelization (page 45)

After Maki led Kujo by the arm out of the room, Suruga whispered in L’s ear, “Hey, Ryuzaki. She’s a little naïve, but beautiful. Things are going to be more exciting around here, eh?”
L looked lost, as if he‘d been asked his opinion about some profound impressionist painting. “Beautiful…? Such things, I don’t know about.”

L describes himself as someone who 1) doesn’t know how to love, and 2) doesn’t know about looking at another person and thinking they’re beautiful.

So there you have it. Aroace L Lawliet :)
