Recent college graduate Musashi Shinonome is visiting the Shitamachi God Heaven pachinko hall after inheriting it from his late grandfather. Inside, he stumbles upon a girl sleeping in a futon, who wakes up upon his arrival. She introduces herself as Hanabi Hana Ariake: a self-proclaimed perfected pachislot machine that has turned into a human. To prove this, she demonstrates her ability to transform and shoot fireworks out of her body. Over the following days, Musashi meets two of Ariake's human pachislot machine sisters—the energetic Versus Ikusa Takanawa and the loving Thunder Rai Nihonbashi. Now, Musashi and the dynamic trio must work together to make the grand reopening of Shitamachi God Heaven a success.

Obsessed with their rather ordinary classmate Ken Kirio, high school students Aimi Miyoshi and Nami Sometani form a peculiar friendship. Every time the girls hang out, they talk about Kirio and fantasize about interacting with the boy they usually just observe from afar. Aimi and Nami are mostly satisfied with the status quo, but they occasionally cannot help but be jealous of those who get to be near their crush—though this still rarely leads them to approach him directly.

The film's story begins with Shinnosuke and his friends of Kasukabe Defence Force experiencing a one-week stay in Tenkatōitsu Kasukabe Private Academy (nicknamed Tenkazu), an elite boarding school that is administrated by a state-of-the-art AI, Otsmun. All the students are given a badge initially with 1000 points and their points are increased/decreased by Otsmun based on their behaviors and academic performance. In there someone attacks Kazama. As a result, his intelligence is reduced, and strange bite marks are left on his butt. The Kasukabe Defense Force joins forces with the school's dropout student council president Chishio Atsuki, who was a former athlete, to form a group of detectives and solve the mystery.
