According to Nostradamus, the world was destined to meet its end in the seventh month of 1999. Presently, it is July 21, 1999. From a young age, Maruyama Sakura has vehemently trusted this prophecy, unwavering in her conviction that she would perish at the age of nineteen. This perception has led her to view everything with minimal regard. With the final days of her life in sight, Sakura exists in an insipid state. However, everything transforms when Mori arrives on the scene. Sakura now has ten days left before the world terminates.
