hi! i saw one of your posts (or maybe it was @mikami ās) saying that L: Change The worLd was not part of the manga DN universe and just wanted to ask if the case was the same with the labb murder cases, Iāve always assumed it was canon due to the fact that beyond birthdayās serial killings were mentioned in the manga
Hi! It is included in the official timeline of events for the manga series in the How to Read Vol. 13 book. But I don't think that it was originally conceived by Ohba and Obata as something that was meant to be included in the manga timeline; I think it was mostly the brainchild of the writer NISIOISIN, and it was published shortly after the manga series ended as official Death Note affiliated content.
The way I picture it probably going is that Ohba just made up a name for a case that L remembered Naomi from without thinking up too many more details about it (as Ohba claims in the HtR13 interviews that he hadn't really fleshed out L's past at all whenever he first started writing him as a character):
And then later on NISIOISIN (an established professional writer in his own right) wrote the novel, and he decided to take the name of that case from the manga and to make up the story behind it. I am not sure how much O&O collaborated with him on it, if at all. The cover art for it was made by Obata, and apparently Ohba has read it and seems to like it, because he mentions it a couple times in the HtR13 interviews. Though it also sounds like some of the things that were included in it were surprises to Ohba.
These were the references to the novel I could find again while skimming the behind the scenes book:
So I think how much you want to take it seriously as canon should be kind of up to you? The way I see it, if you couldn't get the story behind the LABB case from reading the manga itself then it technically shouldn't be considered canon to the same degree that the original manga story is, especially since it wasn't written by Ohba.
But that being said, I do like the novel, and I love B as a character. I like imagining it as part of the storyline too, and so do a lot of other fans. It does somewhat create plotholes for the manga timeline and make Wammy's edgier than it originally appeared as well though, so I don't necessarily take it all that seriously. I always prioritize the manga's version of characters and rules and events over the novel's, and if the novel ever conflicts with the manga I usually ignore the novel's spin on things in favour of the manga's. To me the novel is more so the canon source for stuff about B himself than for stuff about Wammy's and the other previously established characters, if that makes sense. In my eyes it's like a fun additional thing you can look to when creating fan content, but the main source of material for when I do critical analysis of the original story and so on is just the manga itself.
