I wasn't questioning the guide's canonicity inasmuch as the validity behind certain statements.
The manga serves as a rewrite of the original webcomic while the anime is merely an adaptation of the manga. Nothing confirms it's the new canon as of now.
No, I mean, the guide is official, and even though I am not entirely sure Murata and ONE made it themselves yet, I know some of the information there came from them as it revels some new stuff. But I am asking if you think the guide was only meant to be valid for the anime, because I think it is hard to believe ONE or Murata would just specify that that information is only valid for the anime version of the characters, instead of just answer questions about the characters themselves.
And, as I said, I know now the translation was wrong, it only means planet, but resuming our conversation from the other day, we agreed there are two versions of the story, and both are canon, so, if the ONE and Murata gave new information and explanation in that guide, does that mean that would make the anime a third canon? as it comes directly from the author itself and if not, then the information given there must be canon to the manga?
I am not sure, it got confused when the author itself is giving information and explanations for the animated version of his work, we usually know the anime is just an adaptation of a manga so the canon is clear there, but here we have the author itself being involved in a guide that maybe it is only meant for the anime or maybe it is meant to the characters in general...
...in any case, the important part is to see if it was not only made with the help of ONE but to know if ONE himself wrote those descriptions.
