One day, he has a stroke of luck: he's hit by a runaway bus and reincarnated as his game character. But something's gone wrong. . . Instead of the invincible warrior he mains, he's in the body of Nacht Schatten, the alluring dragon princess he made as a joke! Nacht's build is anything but optimized-she would never survive in the cutthroat world of an isekai story! And more to the point, she's a girl!
But perhaps things aren't as bad as they seem. Perhaps Nacht Schatten is more capable than she appears.

As Nacht's battle with the ancient demon Rinoa reaches its climax, the overpowered demiwyrm from another world is finally granted her wish and hears the story of what happened between the Hero and Rinoa's grandfather, the Lord of Calamity. This knowledge, of what happened to the two others who came from her world a thousand years ago, brings Nacht one step closer to answering the questions lingering in her mind: What is the link between this world and the virtual reality MMORPG Real World Online? What drives Rinoa to seek revenge against humanity? But something even bigger than an ancient demon lurks on the horizon, and by the time her battle is finished, Nacht Schatten will regret having left her servant Aisha to handle things on her own. . .
