Haruka Sayaki lived life only to find herself in the hands of death at the pinnacle of her misery. In response, a demon decides to make her last wish become reality - the chance to relive her life once more. The supernatural being's actions are neither out of kindness nor pity, but for the chance at some entertainment. It's not on her side, but not necessarily against her or so it seems. In fact, this time, the chances of success are even more slim than they previously were. She doesn't recall the majority of her memories and was placed in a seemingly random situation with no real idea of what to do. With no real will to live to begin with, she attempts to untangle the complex web of mystery, lies, physiological factors, and deception she's caught in before she even realizes it. The odds are against her and it might as well be considered impossible to get a perfectly happy ending, but at this point, she might as well give it a chance. At the very least, she can hope reach a slightly better ending. That or something far worse.
