What I am asking for may be very broad so please recommend the ones you like, not the ones that just fit the category. I am searching for a novel or manga with either a female or male main character. I would like these characters to be somewhat overpowered. It is fine if they are not overpowered from the start, but I would like for them to be. I would like them to be somewhat emotionless. Not completely emotionless, but kind of socially awkward I guess. I would also like to have no annoying characters. I just want the main character’s companions to not be stupid and irritating. If it’s a antagonist or something similar, they can be annoying. It’s their job in a sense. I do not mind if it is a revenge story. Please do not recommend me any stories with a boring plot. Thank you for all your help.
