I'm afraid we don't have enough data to determine the creator. It might be someone who is really into a specific genre or fandom and decided to create this fanfic. There are so many fanfic writers out there, and without more context, it's impossible to point to a specific person.
Since we have no information about the specific fandom it might belong to, we can only guess. Maybe it's a fanfic where a character has some sort of special power related to blood and has to face a threat in the form of a worm - like creature. Or perhaps it's a more symbolic story where the 'blood' represents family ties or heritage and the 'worm' represents a corrupting influence that this heritage will eventually expose. But again, this is all speculation without further details.
I don't know who created the 'worm online story' as there's no information given. It could be an individual writer, a group of storytellers, or even a company for some educational or entertainment purpose.
I don't know who created the 'worm never ending story'. There could be many independent storytellers or it might be a relatively unknown work by an individual.
The term 'crashing out worm fanfic' is rather ambiguous. It could be that in this fanfic, there is a worm - like creature or entity, and the 'crashing out' could refer to it escaping from a confined space, or perhaps it could be about a digital or technological 'worm' that is crashing out of a system. Maybe it's a unique take on a known story where the author has introduced these elements to create a new and different narrative.
There's no way to tell who created the 'blood in roses best story' just from this title. It might be someone who writes in a very niche genre, like dark romantic or gothic literature. Maybe it was written by a local author in a small community for a specific audience, or perhaps it's part of a larger collection that hasn't gained wide recognition yet.
Well, if it's a relatively unknown fanfic, it might be a bit of a hunt. First, consider reaching out to fellow fans of the genre or related works. Social media groups dedicated to fanfic can be a great resource. You can post a query about it there. Additionally, some smaller, niche fanfic platforms might also have it. However, these might not be as well - known as AO3, so you'll need to do some more digging. It's also possible that it's a self - published or privately shared fanfic, in which case it could be much harder to find.

I'm sorry, but I have no idea which author is behind 'out of the dark sakura fanfiction'. Fanfiction is often created by a wide variety of individuals, and without some sort of attribution or more context, it's difficult to determine the creator.

Since I don't know the specific 'worm dragon fanfic', it's hard to say. But it could be the worm dragon itself as a main character. There might also be a brave adventurer or a curious scientist who is trying to understand or interact with the worm dragon.
