It's not a straightforward answer. Sometimes Domino is shown as having a black appearance in comics, but there are variations across different storylines and artistic renditions.
I'm not sure. It depends on the specific context and source of the story. Some stories labeled as 'Domino' might be based on real events, while others could be purely fictional.
As of the current Marvel Comics canon, there's no indication that Domino is gay. Her focus is more on her superhero activities and the challenges she faces in the comic universe.
Well, typically, it's a good idea to begin with the earlier works of RH Sin as they often lay the foundation for the themes and styles explored in later novels. However, if you're more drawn to a specific genre or theme, you might want to start with the novel that focuses on that.
I recommend "I've become a curse mark" and "Naruto: The Strongest Kakashi". Both of them were stories about Gunmaro's transmigration to another world. The former was based on the curse mark, while the latter revolved around Kakashi. The two novels had compact plots and loud titles. They were suitable for readers who liked light novels, doujinshi novels, and Naruto novels. I hope you like this fairy's recommendation. Muah ~😗
