Upon first seeing Earth from the Azatos Empire's survey ship, Chief Investigator Liza Luna plans to eradicate every lifeform on it immediately, leaving behind only useful resources. While surveying the planet, Liza discovers that human civilization has evolved at a pathetic rate compared to other lifeforms. Liza makes her way to the surface of the planet to properly inspect and understand its inhabitants. Still convinced that there is nothing beneficial to be found, the investigator makes her way into a cafe to gauge the planet's food culture.

Kazuma Yagami is a user of Fuujutsu, the ability to control the wind. He returns to his old home, the noble Kannagi household, after being banished four years ago for his inability to control fire and his subsequent defeat in a duel at the hands of his younger cousin, Ayano Kannagi. Returning after such a brutal exile already gives rise to many conflicts, but to make matters worse, several Kannagi family members have recently been murdered with Fuujutsu. This leads the Kannagi family, including the hot-headed Ayano, to suspect Kazuma as the culprit. Now, Kazuma must not only clear his name, but also aid the family he shares a mutual hatred with, in order to discover the true identity of the killer.

In Tokyo, there exists a peaceful cohabitation between supernatural creatures—elves, dwarves, vampires, and more—and humans. However, contrary to history, powerful dragons once ruled over this world of creatures and humans but have since disappeared. Consequently, a diabolical group under the alias Nine, who seek the miracles of the once godlike dragons, stirs up trouble in the streets of Tokyo, commiting mass murder and causing destruction. To combat the dangerous group of Nine, the police organize the Special 7—a group of highly skilled professionals whose abilities exceed those of ordinary humans. Caught up in a bank robbery turned hostage crisis, Seiji Nanatsuki, having recently become a detective, has a chance encounter with Shiori Ichinose, a member of Special 7. Assisting with the resolution of the robbery, Seiji is recognized for his clear sense of justice and refreshing character, suddenly earning him a spot on the elite unit. As he takes on new missions, Seiji finds that being a detective as part of Special 7 isn't the police work he expected, where working alongside a team of different species with special abilities and vibrant personalities brings unpredictability to his daily life and police work. While the everyday crime in Tokyo continues, Seiji and the Special 7 will fight not only to resolve special cases, but also obstruct the ill-intentioned plans of the merciless group of Nine.
