Hi guys srry if im being a noob but im very curious about what happened in Chapter 33 Page3.
You can obviously see that the biker shot Nishi directly in his head but Nishi quickly reacted and shot with hix x-Gun the biker too. The bikers head blew up but nishi remained ok.

Now im not sure why Nishi survived the shot. Is it because by killing the person who shot you, you don't die or is it a certain trick that he used ?
