One day a man sells his soul to a demonic spirit in exchange for his daughter gaining a life without burdens. However, after six years, the man observes that living without any burdens has shaped his daughter into a narcissistic, cocksure, and selfish girl. Feeling regretful, the man sneaks his way to the world of the demonic spirits, frantically shuffles through files, finds the terrible contract, and rips it apart, officially freeing his soul.
The demonic spirit is furious upon finding it and is prepared to ask his boss for permission on inflicting as many burdens, as much misery and woe as demonically possible. However it is now when he receives a warning slip (due to neglecting quite a lot of his work) informing him that his authority in inflicting pain had also been reduced.
The demonic spirit is at loss before one of his friends suggests that he simply take away the man’s ability to sleep. Apparently the longest record of a human functioning without sleep is eleven days, and by the end, the lack of sleep had made the record maker vision impaired, and had permanently harmed his memory and cognitive abilities. The demonic spirit is filled with glee at the idea of seeing the man who tricked him slowly break down before his eyes.
Follow the man who is unable to sleep and must seek the demonic spirit for forgiveness. He has a time frame of eleven days and within this time he becomes an extremely unreliable narrator, doing acts he later has no recollection of doing, or having no reasonable explanation of the rationality of his actions. He becomes caught up in several large scale crimes without being fully aware of them. Near the end of the story it is extremely difficult to differentiate what is real in the man’s mind and what are his hallucinations.
