I'm not sure as I haven't read it specifically. But generally, a 'regressor' in novel terms might imply a character who goes back in time or reverts to a previous state. So perhaps this novel is about a character who is not such a regressor and has a different kind of story, like a forward - moving adventure or a story based on present - day challenges.
Sadly, I'm not aware of the author of 'im the max level newbie novel'. There are so many novels out there that it's difficult to know every author. You could also try reaching out to local libraries or bookstores to see if they have any information on it.
I'm not sure specifically as I haven't read it. But generally, a 'newbie' in a novel often refers to a new or inexperienced character. And'max level' might imply that this newbie has reached an extremely high or top - level state in some aspect, perhaps in power, skills or knowledge within the context of the story.
I'm sorry, I haven't read this novel specifically. But generally, it might be about a sister's story in a world where she has a queen - like status. Maybe it involves her journey to gain power, deal with court politics, and relationships with other characters.
Shiny Pokemon are rare in the games, so in fanfiction, they're seen as valuable. Writers often make them high - priced to create a sense of exclusivity. For example, a trainer might have to go through many difficult quests to obtain a shiny Pokemon, and thus it becomes a symbol of great achievement and is priced accordingly in the fictional economy of the fanfiction.
The potential for different storylines. As I mentioned before, they could be on an adventure, training, or uncovering secrets. All these storylines can keep the readers engaged. For example, if they are on an adventure, the readers will be eager to know what new places they will visit and what Pokemon they will meet. If it's about training, we can see the Riolu grow and develop new abilities, which is always exciting in the Pokemon universe.
