People say that fireworks soothe the spirits of those who have passed. For Tomoya Sugisaki, Aoi Harukawa, and Ryou Kobayashi, the pyrotechnics were what brought them into contact with the Summer Ghost. Thought to be the spirit of a young woman who took her own life, this apparition appears only in one particular place and can be seen solely by those who are close to death.
Tomoya is a creative mind burdened by the pressure of getting into a top university. Aoi is a timid girl constantly tormented by classmates. Ryou, once a basketball prodigy, had to abandon his dream after receiving a bleak diagnosis. What ties these three together is their shared ability to perceive the Summer Ghost, who is rumored to answer any question about death—something the teens are desperate to learn.
Unhappy with their first encounter, Tomoya searches for the Summer Ghost again. Yet each visit peels back more layers of her mysterious existence. Each time he approaches, the veil between worlds thins further, revealing fragments of her past that defy explanation. His curiosity grows, yet the answers he seeks become more elusive with every encounter.
