Intriguing and mysterious, ACCA: 13-ku Kansatsu-ka is a politically-themed mystery that reveals a world of diverse cultures and lifestyles, with intricate connections between its characters, as the truth of the coup d'état slowly unfolds.

For the last three years, Teikou Middle School has dominated the national basketball scene with its legendary lineup: the "Generation of Miracles." It consisted of five prodigies who excelled at the sport, but a "Phantom Sixth Man" lurked in the shadows and helped earn the team their revered status. Eventually, their monstrous growth jaded them from the sport they loved and made them go their separate ways in high school. In search of new members, the Seirin High School basketball team recruits Taiga Kagami and Tetsuya Kuroko, two freshmen who seem to have significant differences in abilities. Having returned recently from America, Kagami has both a natural aptitude and relentless love for the sport. Meanwhile, Kuroko lacks presence and exhibits no outstanding athletic talent. However, it is later revealed that he is Teikou's Phantom Sixth Man—the player once part of the Generation of Miracles. Kuroko wants to prove to the Seirin team that he is strong in his own way. Seeing his conviction, Kagami forms a dynamic partnership with Kuroko, the latter promising to support Kagami's "light" as his "shadow." Alongside their new Seirin teammates, they aim to conquer the upcoming Interhigh championship, but the reappearance of Kuroko's former teammates complicates their plan.

With the Interhigh Championship finally over, Seirin's basketball team refocuses their efforts, training harder than ever to get the chance to participate in the Winter Cup. Both Tetsuya Kuroko and Taiga Kagami see old friends walk back into their lives, providing a challenge both on and off the court. As new skills are developed and new alliances created, enemies from various teams—giants of high school basketball such as Yousen, Shuutoku, and Touou—stand in the way of Seirin's steadfast attempts to get to the top. All of these schools prove to be formidable foes whose abilities progress exponentially, while Kuroko struggles to find a balance between his resolve to play as part of a team and his desire to win. With old wounds reopening, new challenges to face on the court, and a new set of foes—the "Uncrowned Kings"—vowing to defeat the new hopefuls, will Seirin ever be able to achieve their dream of beating the Generation of Miracles?
