After her crushing defeat of 21-0 at the National Junior Badminton Tournament, Nagisa Aragaki's love for her sport begins to distort. Unable to deal with the shame of loss, she starts to terrorize the members of her high school badminton club. Her grueling drills bring some to the verge of tears while others quit the club outright. With the team losing members and new prospects being too terrified to join, the future of the badminton club looks exceptionally grim. That is, until Kentarou Tachibana joins as the new head coach. Not only is he an Olympic-level player, but he also comes bearing a secret weapon: Ayano Hanesaki, the girl who defeated Nagisa six months ago. However, Ayano is not the rival Nagisa remembers, but a girl with conflicted feelings wanting to distance herself from badminton. With her future in sports now on the line, Nagisa must find a way to face her fears of inadequacy, heal her rival's troubled heart, and bring victory to Kitakomachi High School's badminton club.

The mauling of a vicious, prehistoric-sized African elephant makes international headlines. Featured in reports of the aftermath, the sole survivor of one of the animal's rampages attributes its death to a lone, unarmed man—unknowingly describing Yuujirou Hanma, nicknamed the Ogre and often labeled as the strongest creature on Earth. Elsewhere, Yuujirou's 18-year-old son Baki spars with an equally formidable beast: a praying mantis. Content with his training and determined to overtake his father, Baki abducts American President George Bosch to begin his plans. This leads to his deliberate imprisonment at the infamous Arizona State Prison where Oliva Biscuit resides—the strongest man in the United States and an inmate allowed to leave of his own volition. Hoping to gauge his abilities, Baki challenges Oliva to a fight; but Oliva is preoccupied with his eccentric rival, Jun Guevaru. Known as the Second, he is the only other prisoner to receive special treatment from the guards. Bewildered yet intrigued, Baki learns about his fellow inmates and tolerates the hellish conditions of prison life while waiting for an opportunity to present itself.

When the head of the family announces his retirement, the six Miyanomori brothers are left to vie for his position. With 18 years of experience separating the oldest and youngest brothers, frustration and competition are rife. As a result, Haru is left to deal with each of the vastly different siblings and explore the depths of their true selves. All the while, a greater conflict lies in wait with the potential to destroy everything their father has built for them.
