After a freak accident, Keiko Igarashi (and her dog Kumo) is summoned by a goddess desperate to save the realm from tragedy and evil. And with Keiko's skills and pure heart, she's exactly the kind of hero this world needs! Except...she wants no part in a hero's journey. She's read enough manga to see where this is going. She's not cut out for the hero life; she simply wishes to spend her days living peacefully in a small village, nice and comfy with her dog.

But then she sees a familiar face in the tavern—the Demon Prince from her favorite light novel series! Somehow she's been transported into the novel four years before the villain rises to power and takes over the realm. (Not to mention, she used to have a huge crush on him back in the day. Just a little bit.)

But he seems so different now... And when she's forced to accompany him on his journey to the capital, she wonders how he ever became the terrifying villain, and whether or not she can change him for the better.
