I hate how people compare manga to real life. Are we just not gonna question the Kure clan and their powers? How about Ohma and his powers? Or how people are getting punched and slammed into the ground, and the walls, cracking/breaking them, and still fighting like it was nothing? Or how Niko deflected a damn bullet with his hand? I'm pretty sure someone getting their face dragged across the concrete and surviving at this point shouldn't be too surprising.
