Nineteen-year-old Naruse Noka works hard everyday to become an idol, doing everything she can to get the job; however, her reality is twisted when she meets a strange girl on the Human Zoo of Hell—a place where you can see the lives of those who failed. The manga is based on the song "Spinal Fluid Explosion Girl" by rerulili, sung by the VOCALOIDs Hatsune Miku and GUMI.

The story centers around Mizuki Hijiri, a high school girl who just transferred schools. At her new school, she has a fateful encounter with boys suffering from chūnibyō (adolescent delusions of grandeur). There is Noda who dreams of becoming a hero, the tragically handsome otaku Takashima who only likes 2D girls, Nakamura the supposedly "reincarnated" angel or devil, and the self-professed string-puller Tsukumo.
