With a title inspired by “Stomiiformes”, an order of deep-sea ray-finned fish called, this story follows Tomioka, a late-night security guard at a supermarket who laments his drab and solitary life. Feeling it unnatural to exist alone, he wishes upon a shooting star one night for a true friend. Soon, a mysterious woman appears in his life. She is Azusa, a next-door neighbor who instantly falls in love with him. But as the kind of social awkwardness, Tomioka is obtusely unaware of her feelings for him. Can love bloom between these two? Especially when compounded by the sudden emergence of a homeless guy, who calls himself a “life wanderer”, and then an enigmatic death threat in the form of a letter that reads: “You will lose your mind within a year and die”. Life is suddenly turned upside down.
