Mizuki Kawase is a 24-year-old office worker who's worked for her company for over three years.

Treating the act just like a sport, Mizuki has now locked on to a handsome new male employee named Kouki Asahina, who was assigned to the same department as her. Dead-set on making Kouki hers, Mizuki tries every method she knows to seduce him, but he seems completely unmovable. At first, she thinks that he's no ordinary person... but maybe he's actually just an idiot?! Who will win in this comedic romantic battle between the assertive beauty and the handsome, but air-headed younger man?!

Once, there was a man feared as the strongest hitman in the underworld. His code name was “Nightshade.” Master of a thousand techniques that sever the human nervous system, he could strip his targets of all five senses and lead them to certain death—a “Reaper” known to everyone in the criminal world. But that man no longer existed. To protect a certain girl, he defied an order and was executed by the very organization he served. Seventeen years after his death, no one could have imagined it: the man has been reborn and now lives as an ordinary high school student.

"Lets redefine the laws of the world." In 2032, an unprecedented theory in physics was proposed, fundamentally altering the nature of reality. From this, certain physical phenomena began to manifest in the form of girls—beings known as Fairy. These entities brought humanity both immense blessings and catastrophic disasters. 7 years ago, Fairy Hazard struck, devastating the city of Kobe—only for it to later be rebuilt. Living there is a boy named Kanae, who believed he was leading a peaceful life...until the day he heard her cry for help. "I killed 15 million people...with my own hands, all at once." A hidden truth about the world, and an unforgivable sin. Thus begins the fugitive journey of a boy and a fairy. From an award-winning author comes a deeply moving epic—now boldly released!
