I am okay with the suggestion of op, although something should be noted on this matter.

As someone already pointed out, quite a few people would accept the information of the guide book as canon. Think about it, in this world we have both Catholics (manga+guide book) and Protestants (manga only) and both of them believe their claims to be legitimate with "more strict people" usually being a minority. I do not think there is a pressing need to change the wiki because of the huge amount of work, but if you are "that devoted" that's fine too.

And frankly it is true that manga is the original work and should be the most canon information source. But in reality manga's audience is just one fraction of the anime audience, and base on my everyday observation people consider anime series far more canon than the manga. You have to recognize the fact that in this fandom or reddit the people are usually a very specific group of core users. I am not saying we should change the way how we view the anime to cater anime-viewer-tastes, but another thing that can be improved for the wiki is to provide more details on the anime-only characters and their scenes, since the basic function of a wiki is for "common" people to search the stuff they want.
