Yes, Single Female Lead, no harem no side chicks

It's realistic fantasy about fight and martial arts, dudes are already fighters, I'm sure you will love this but I recommend it for girls too, dudes (if you got any female friends who read novels) recommend this to them because I'm going to introduce various badass female characters in future, that can turn you lesbian or straight however you prefer

Next there won't be no cheat or plot armours, it shall be all about brain and brawls, though main character is already way too overpowered from start but it's entertaining, now I won't disturb anymore!
