One day, I was suddenly dragged into another world by my step-sister. When asked "Where is the hero?", I immediately judged it as a troublesome situation and pointed at my step-sister without hesitation. "It's her." "That's mean, sis!" What's so mean about it? Who else but she could be the hero, with her beautiful appearance, brilliant mind, and athletic abilities? She's loved by God. ...So, I'll pass for now because it looks troublesome. This is the story of a lazy older sister, a perfect superhuman girl, and her unconventional adventures in another world. (*Note: The protagonist is almost invincible from the start.)
