The time is Sengoku. Japan is fractured into many independent nations entangled in ceaseless war. At the center lies Ashina, a land of sacred earth and ancient mystery. Two decades after Sword Saint Isshin Ashina reclaimed the region in a brutal coup, a new threat emerges from within: The Interior Ministry. Desperate to protect his homeland, Isshin's grandson Gen'ichirou turns to forbidden powers. The only hope lies in a kidnapped boy—the Divine Heir—and his silent protector: a loyal shinobi known only as Sekiro. This is the story of a lord and his retainer—and their quest to restore balance to a nation on the edge.

Sentenced to death, ninja Gabimaru the Hollow finds himself apathetic. After leading a blood-soaked life, Gabimaru believes he deserves to die. However, every attempt to execute him inexplicably fails. Finally, Sagiri Yamada Asaemon, a fledgling member of a famed executioner clan, is asked to take Gabimaru's life; yet Sagiri makes no move to kill him as requested. Insisting that Gabimaru will not die because of his love for his wife, Sagiri instead offers him the chance to obtain a full pardon for his crimes. If he can travel to the island of Shinsekyo and obtain the Elixir of Life—which supposedly grants immortality—and bring it back for the shogun, then his freedom will be assured. But of the many who have traveled to Shinsekyo in search of the mythical Elixir, not a single person has returned sound of mind, if at all. Though unaware of the numerous dangers ahead, Gabimaru decides to accept the offer—alongside ten other death row convicts—in hope that he and his wife may finally live in peace.

As the year nears its end, the time for final exams arrives at Rigarden Magical Academy. Despite being the only student without any magic aptitude, Will Serfort aims to score perfect grades in every subject, which would allow him to ascend to the Wizard's Tower and reunite with his childhood friend, Elfaria Albis Serfort. However, Will's hard work comes tumbling down when he fails the very last, biased exam, disqualifying him from entering the Wizard's Tower. Meanwhile, Elfaria and the other Magia Vander—the five most powerful mages—perform the annual ritual that protects their world from the dangerous Celestial Hosts. As the ritual temporarily leaves the Magia Vander drained of magic, a large army of monsters suddenly appears and begins attacking mages and civilians alike. To make matters worse, the mages are unable to hold off the invasion due to the monsters' special weaponry that nullifies their magic. Refusing to let the world end in despair, Will and his masterful swordsmanship quickly become a cornerstone in stopping the attack. [Written by MAL Rewrite]

In an isolated village, two twins were born, separated by day and night.

On an otherwise inconspicuous day, a group of armed men riding in helicopters, referred to as "dragons" by the citizens, assaults the village in search of Yuru, killing every adult on sight. When Yuru attempts to meet up with Asa and flee, he finds a dead body instead—on top of that, the person who killed her claims to be Yuru's true twin sister. Before the woman can capture him, Yuru is rescued by a man named Ryuu "Dera" Tadera, an outsider who frequently visits the village. However, it is not long before the two are cornered. In a last-ditch effort, Dera makes Yuru give a gift to the deity of the village, summoning a pair of daemons whose existence is bound to reveal the truth behind these chaotic events.

Seventeen-year-old Jirou Azuma lives a quiet life with his grandfather, utilizing his supernatural ability to speak with animals to befriend and protect them. Both Jirou and his grandfather are descendants of a long-standing shinobi clan, training in combat to keep the art of battle alive within their family. Jirou's life is thrown into upheaval after rescuing a seemingly normal black cat, Ragou, only to discover that the cat is actually a mononoke—a demonic spirit that has long been at war with mankind. When a hostile mononoke comes looking for Ragou, Jirou uses his shinobi training to jump to the cat's defense, but immediately suffers a mortal wound. Faced with the decision of whether or not to devour Jirou's fading energy and restore himself to full power, Ragou instead chooses to give his remaining energy to Jirou. Reviving the boy, the transfer also grants him great supernatural powers that complement his own shinobi fighting style. This act is witnessed by Ryousuke Shiba, an officer in the Bureau of Espionage whose job revolves around dispatching aggressive mononoke. Shiba extends Jirou and his grandfather an offer: to join the Bureau's new squad, Black Torch, and help them battle powerful mononoke who seek to devour innocent people. [Written by MAL Rewrite]
