Dimension: the Strongest Killer Driver

There are three memories in my brain. One is a killer, one is an otaku, and the most powerful one is: the protagonist from Assassin's Creed. Killers and assassins are both butchers hiding in darkness, and I am the god of death who constantly shuttles between darkness and light... Death may be that simple! Moreover, I also have a system that is not fully activated. He can obtain skill points by killing targets until he becomes a god. As I repeatedly played the game of killing and being killed, for some reason, there were more and more beauties around me, which was really annoying...
