Guided by her visions revealing the location of the King of Salvation, Jeanne Kaguya d'Arc flees with the polymath Leonardo da Vinci from the West Star to the East Star. There, she encounters Nobunaga Oda—the son of a local feudal lord who, following a brutal defeat dealt by an enemy clan, has sworn to conquer the world with his friends. Quickly convinced that Nobunaga is indeed the King of Salvation, Jeanne pledges allegiance to the Oda clan. Meanwhile, King Arthur, the ruler of the West Star, sends his ruthless general Gaius Julius Caesar and his combat machine army to conquer Nobunaga's planet and seize the Holy Grail. Although Kaguya believes that Arthur is the King of Destruction, the reckless behavior of Nobunaga The Fool—who named his own combat suit after his nickname—on the battlefield sows doubt in his capability as a leader. With the help of Himiko, the Yamato Queen, Nobunaga and his clan must unify in order to overcome tragedies, recover from betrayals, and eventually save the world.

Tousuke Rokudou is a first-year attending Aomori High, a school full of delinquents. He is often bullied by his classmates due to his incompatibility with their behavior, the only exceptions being his two good friends who are also social outcasts. Frustrated at the way they are treated, the three wish they could stand up and claim the fun, peaceful school life of their dreams. However, Tousuke's life takes a drastic turn when he receives a package from his late grandfather containing their family heirloom, a scroll said to possess the power to save him from impending danger. Upon holding the scroll, a sudden glow emanates, leaving a strange mark on Tousuke's forehead. Thinking that he's received the means to free himself and his friends from their daily treatment, Tousuke is shocked to find out that its effects are far different than what he had imagined. Although his bullying continues, he realizes that the mark from the scroll acts as a charm, capturing the hearts of delinquent girls—in particular, Ranna Himawari, the strongest of them all.

The Labyrinth is an expansive space deep underground where humans live in clusters known as colonies. Over the years, the surface has become a distant memory—even perhaps only a fantasy to those who have never experienced its wonders. Making sure humanity survives the harsh conditions of the underground, a colony's citizens can take on a variety of specialized jobs. These include Workers, who mine precious ore to fuel the colonies, and Markers, who journey into the Labyrinth's surprisingly lush environment to bring back information that eases navigation. However, humanity also faces a threat to its existence—creatures called kaijuu whose sizes range from that of a small child to an enormous building, and are hostile to any human they see. Moreover, kaijuu that are large enough can force their way into the colonies, further increasing their threat level. Memenpu is a nine-year-old college graduate whose inventions have greatly benefitted the Workers in her local colony. Recently, however, she has been dreaming of a place with a neverending ceiling not bound by bedrock. These aspirations fuel her desire to become a Marker and explore the Labyrinth's vast unknown in search of such a fantastical place. Despite her father Gagumber's vehement disagreement, a certain incident with the kaijuu jumpstarts a dangerous yet exciting adventure that will surely alter humanity's course forever.
