One day, out of the blue, I was summoned to another world, dragged along with my stepsister.

Their very first question was, "Where is the Hero?" Immediately recognizing it as a hassle, I unhesitatingly pointed at my stepsister.

"It's her." "Big sis, that's awful!"

What's so awful about it? Who else but you, with your beautiful looks, brilliant mind, and athletic prowess—truly beloved by the gods—could possibly be the "Hero"?

...So, since that looks like a hassle, I'll pass for now.

An off-the-beaten-path adventure in another world, starring the lazy stepsister of a flawless, superhuman girl.

(Note: The protagonist is virtually invincible from the start.)
