According to the information provided, there were also some anime and doujin novels that were more popular, such as "Full-time Hunter,""Attack of the Giant,""Dragon Ball," and so on. At the same time, some authors might add content from other worlds. For example, Infinite Starry Sky would add accelerated worlds, black contractor, and so on. But overall, Naruto, Grim Reaper, and Pirates were still the mainstream subjects of Doujin novels. I hope you like this fairy's recommendation. Muah ~😗
