One day, out of the blue, I got dragged into a different world by my stepsister. The first thing I heard was, “Is the Hero here?” I immediately knew it was trouble and without hesitation, I pointed at my stepsister. “It’s her.” “Big sister, that’s so mean!” What’s so mean about it? Who else but you, blessed with beauty, brains, and athletic prowess, could be the “Hero”? So, I decided to pass on this troublesome task. This is the story of a lazy older sister, who is a perfect supergirl, and her adventures in a different world. (Note: The protagonist is practically invincible from the start.)
