Harem King System: My System is a pervert

In my past life, I was the universe’s punching bag. Struck by lightning twice? Check. Lost my family? Check. Lost the ability to feel touch or emotion? Double check. I hated the world so much I tried to become a serial killer, but I was so unlucky I couldn't even get that right. My only escape was the novel Abyss Walkers Chronicles. When the author dropped the book, I tracked him down to kill him. Naturally, with my luck, I tripped and died instead. I woke up inside the novel. Not as the hero, or a cool villain, but as a nameless background extra. I thought my bad luck had followed me, until my 18th birthday. That’s when It awakened. [System Initialized. Welcome, Host. OOh Nice Ass.] I have the looks. I have the knowledge of the future. And now, I have a System that rewards me for being absolute trash. It wants me to conquer women, steal their bloodlines, and commit vile deeds to earn points. By day, I am the perfect student, the hero the Academy adores. By night, I wear the mask of "Zero," the greatest villain this continent has ever seen. To the world, I’m a savior. To the System, I’m a playboy. But in reality? I’m the one pulling the strings.
