Recently I rewatched the episodes of the anime where Allen gets his Crown Clown and the thing with the name of the Akuma who appears during this arc has always weirded me out. If some of you have ever checked the D.Gray-man wiki, you will know this Akuma is known as "Thread", with the wiki even saying it's a name the anime gave him.

However, as far as I know, this Akuma has always been unnamed. Neither in the manga, anime or extra material like databooks his name has ever being stated. He has always been referred as just a "Level 3 Akuma" without any other name, even in the anime the credits just refer to him as such, and there's an episode of the D.Gray-theater where the show outright makes fun of the Akuma because he doesn't has a name.

Saying that, I want to ask if anyone knows the source of name "Thread" for this fellow and is it's an official name from some obscure source or is just a name fans invented to make him more identifiable. Sorry if this post comes as random, but it's something I have thought for a while and if someone is more informed than me I would like to know it.
