After Being Forgotten by the World, I Became an Eraser

The day I awakened my powers, the bully was slapping me in the face with his cell phone. "Smile, you loser." In the next second, his sense of existence was completely erased, and even his parents forgot that they had such a son. I was addicted to the pleasure of being an "eraser" until I met the only girl who was immune to my abilities. "Welcome to the Forgotten Containment Station," she smiled. "By the way, you were supposed to be the first person to be erased."
