Continuation of Ushio to Tora TV series.

On a train to her new middle school, Momoka Sonokawa is preyed upon by a molester, only to be rescued by a girl wielding dual pistols. The girl turns out to be Miou Ootori, Momoka's upperclassman and president of the Aogiri Academy's Survival Game Club, called Sabage-bu for short. Noticing Momoka's aptitude with a pistol, Miou takes a liking to her and tries to persuade her to join the club. In spite of her steadfast refusal, Momoka inexplicably finds herself a member of Sabage-bu. Sabage-bu is anything but a typical middle-school club. Its members' socially awkward behaviors scare Momoka. Their personalities range from the fanatical to the completely delusional. They do not hold back from walking around public areas wearing ghillie suits or even bungee jumping from the school building. Thrown together with this collection of survival game maniacs, the zealously ordinary Momoka must somehow adjust to her unexpectedly wild school life.

Despite having seemingly returned to their normal lives, Kei Kurono, Masaru Katou, and Kei Kishimoto are forced back into the lethal game after Gantz's recent activity. The black sphere continues to summon recently deceased people to fight alien invaders. And having survived the two previous encounters, the trio are more than prepared for the upcoming missions. As they progress through the tournament's stages, the three proceed in their attempt to earn 100 points, which is said to be the only way to leave the parallel dimension for good. However, with the constant onslaught of alien invaders and the threat of imminent death, they must first focus on the task at hand—immediate survival.

Tsukasa Akeuraji always dreamed of becoming a competitive solo figure skater, but starting too late in life meant his ambitions never got off the ground. Now barely scraping by, he takes on an assistant coach job, resigned to a future far from the one he once imagined. Before his first day, Tsukasa meets Inori Yuitsuka, a shy fifth grader sneaking into the rink to practice. Captivated by figure skating, but held back by her mother's overprotectiveness and her own self-doubt, Inori has never been encouraged to pursue her passion until she encounters Tsukasa. Beneath her personality lies great potential, waiting to be unlocked with the right guidance. Moved by Inori's determination to change and reminded of his own struggles, Tsukasa offers to coach and help her chase the dream she has been too afraid to voice. While the road ahead is long and filled with unfamiliar challenges and rival skaters, Inori dedicates herself to the art and strives to one day reach the Olympics and become a medalist.
