In a world overtaken by war and conflict, Hypnosis Microphones—devices through which a user channels lyrics that can affect the listener's brain and even cause physical damage—were introduced to the masses by the Party of Words. Revolutionizing warfare, Hypnosis Mics have transformed words and music into the sole weapons used by gangsters, terrorists, and the military, with physical weapons having been banned from use. As a result of swooping in during the chaos, the all-female Party of Words rules over the Japanese government. Women in Japan now live in Chuuouku, while men battle over surrounding territories outside the ward through rap battles. With intentions unknown, the Party of Words begins to gather the former members of the now-disbanded legendary rap crew The Dirty Dawg to fight not for territory or war, but for their respective crew's pride and honor in the greatest rap battle of all time. The first Division Rap Battle is about to commence, and practice is not something these rappers are going to need.

Mikoto Shinozaki is a high school student lacking in social awareness. In addition, due to his untidy appearance and low self-esteem, he is an easy target for bullies. Regardless, any misfortune that falls upon Mikoto is partly his own fault—at least, that is what Yuki Fukuzawa, the most popular girl in class, believes. With this assumption, Yuki invites Mikoto to join the school's bicycle club, in hopes he can improve himself and gain new friends. Motivated by feelings he has for Yuki, Mikoto has no reason to decline her offer—except for the fact that he does not know how to ride a bicycle. Despite his lack of even the fundamentals, Mikoto cannot get over the image of himself on a bicycle. Eventually, he succumbs to his curiosity and sneaks into the school grounds at night to practice. This begins Mikoto's journey as he pedals his way through the vast world of cycling, where the scenery of his life changes in ways he never thought possible.

Natsuza Yuzuki has been playing rugby as a left-winger ever since he was a child. After enrolling in Doushisha University, he quickly becomes a rising star in the Kansai University League. His dreams are shattered, however, when a nasty motorbike accident leaves him with a spinal hernia—making him unable to be able to play rugby ever again. With no role available other than the position of manager, he accepts his new post and hopes his squad can obtain a league title. Yuzuki's team is an unlikely group, including his stoic best friend and full-back Seiichirou Jingyouji; hot-headed first-year Yasunari Tsuru, who harbors a strong dislike for Natsuza, filling his senior's old position as left wing; and Yuu Mashiro, who is struggling to hold his ground as a scrum half. Despite Natsuza putting his all into training his team for a league title, their squad still feels incomplete. A year ago, Ibuki Ueka, the genius fly-half that was once Doushisha's ace, suddenly quit rugby—and now Natsuza is determined to get him back.
