Set in a dystopian society, the story follows a government program designed to instill appreciation for life by randomly selecting citizens to die at a young age. The narrative centers around a civil servant tasked with delivering "ikigami," a death notice given 24 hours before the recipient's predetermined demise. As he witnesses the varied reactions of those receiving the ikigami, he begins to question the morality and impact of the system. Through these encounters, the book explores themes of life, death, and the value of human existence, prompting readers to reflect on the meaning of life and the societal structures that govern it.
