Yuusei Fudou is out to get back what was stolen from him. The world of dueling has evolved, with Riding Duels becoming the peak of entertainment for the residents of Neo Domino City. They are played on D-Wheels, a hybrid between Duel Disks and motorbikes. After the mechanically skilled Yuusei managed to build his own D-Wheel, his former friend Jack Atlas stole it alongside Yuusei's best card, Stardust Dragon; ditching their decrepit hometown of Satellite, he escaped to Neo Domino City. In the two years since then, Jack has risen to the top of the dueling world, while Yuusei has been making preparations thanks to the help of his friends. With his new D-Wheel finished, he now sets off to Neo Domino City, his only goal to find Jack. Unbeknownst to either of them, there are far bigger things at stake than they can imagine, with puppeteers pulling the strings behind the scenes. [Written by MAL Rewrite]

Hailing from America, Jabberwock—a street basketball team with skills comparable to those of the NBA—has come to Japan to play an exhibition match against Strky, a team of former third-year students who once played in the Interhigh and Winter Cup. However, due to the vast difference in skill, Jabberwock easily wins. Their captain, Nash Gold Jr., mocks the basketball style of all players in Japan by comparing them to monkeys.

Infuriated by the nasty comment, Kagetora Aida challenges them to a revenge match. Because of pride and the belief that the results will be no different, Nash accepts the challenge. Kagetora then assembles Vorpal Swords, a team composed of the Generation of Miracles, including Kuroko Tetsuya and Kagami Taiga, for they are the only ones who stand a chance against a foe that seems unbeatable from every angle.

Kimito Kagurazaka is a commoner with a fetish for men's muscles—or at least that's the lie he must keep telling if he wants to keep himself out of trouble at the elite all-girls school, Seikain Academy. Kidnapped by the school under the assumption that he prefers men, Kimito is made to be their "commoner sample," exposing the girls to both commoner and man so that the transition to the world after school is not jarring. Threatened with castration should his sexual preferences not match the school's assumptions, Kimito keeps up the facade to protect his manhood. But there are eccentric individuals around every corner who begin to make Kimito's life even more difficult. Among them are Aika Tenkuubashi, a social outcast who blurts out whatever comes to mind; Hakua Shiodome, a young genius; Karen Jinryou, the daughter of samurai who is obsessed with defeating Kimito; and Reiko Arisugawa, the perfect student who has delusions of marrying Kimito. Along with the commoner himself, these four girls make up the Commoner Club, which attempts to teach the girls more about life outside the school, while Kimito gradually learns about the odd girls surrounding him.
