If it weren't for some key words, I'd say this chapter was wrongfully added to the manga, but it seems it is indeed part of the manga. Such obvious immersion breaks are never good. Next, the chapter is even inconsistent in itself. I mean at the beginning (losing) girly had no hesitation to scare those random "playboys" off with magic but at the end she can't do that to some mafia thugs who think knives will work? What?
