SSS-Ranked Awakening: Reincarnated as Extra with the strongest system

Also know as Extra's Pov: Reincarnated as the weakest villain! ... Well in most stories there were truck-kun, heroes and villains. In such stories the hero always kills the villains and get the girls and live a happily ever after ending. So what was I supposed to do now that I had reincarnated into the body of a villain, not even a third rate villain a villain that was killed in the early chapters of the novel. This time I wasn't going to die useless, I was going to be a villain the most powerful...the first villain to kill the hero and steal his girls in history. Just watch me!
