Satsuki and Keiichirou Miyanoshita, a pair of siblings, are still grieving the death of their mother. When they move to her old hometown, they find that their new school is an aging building filled with whispers of paranormal activity. At first, they dismiss these stories, but they soon realize the ghosts are real and hold a particular grudge against them.

As night falls, beautiful yet terrifying beings emerge to rule the darkness, striking fear into all living things. These bloodthirsty predators approach, and the water freezes, signaling the inevitable doom of their prey. Fortunately, the vampire population is dwindling thanks to the courageous bounty hunters who relentlessly pursue these nearly immortal creatures. One evening, the Elbourne family suffers a devastating tragedy when their daughter, Charlotte, is taken by Meier Link, a revered vampire lord protected by a legion of monstrous followers. To save Charlotte, the family hires the Marcus Brothers, a brutal band of vampire hunters, along with D, a dhampir armed with a sword—one who possesses the strengths of both vampires and humans but none of their weaknesses. Rushing to Charlotte's rescue, the hunters know that if she is transformed into a vampire by her captor, they will have no choice but to end her life. Furthermore, they must complete their mission before Meier can reach the impenetrable vampire fortress of Carmilla, sealing Charlotte away from human salvation forever.

Boogiepop is a legendary shinigami said to exist unseen. Five years ago, a series of brutal murders caused widespread fear, with some students blaming those deaths on this supposed god of death.

Ceres was a tennyo—a celestial maiden—who descended from the heavens to bathe in a stream. She placed her hagoromo, or feathered robe, on a nearby tree; that robe was her means of returning to the sky. However, a man stole it and forced her to become his wife, giving rise to a family line mingling human and tennyo blood. In the present day, Aya Mikage is a descendant of Ceres and carries a significant amount of tennyo blood. On her sixteenth birthday, she and her twin brother Aki are given a party. But during this "party," Aya's grandfather intends to kill her: unlike others in the family, she possesses tennyo powers and can actually transform into Ceres herself—and destroy the Mikage family. Yet Aya is able to revert, so this transformation occurs frequently. With her protector Yuuhi at her side, Aya must control Ceres and prevent her from reemerging. However, her relationship with a former employee of her wicked grandfather may prove to be a distraction.

Even after death, life is still filled with paperwork and criminals. Tsuzuki Asato is a cheerful, somewhat goofy 26-year-old shinigami tasked with ensuring the dead stay dead and remain in their proper realms. Despite holding this job for over 70 years, he works in the worst division with meager pay. He also has a habit of driving away partners—shinigami are required to work in pairs—but he may finally have found one who sticks: the stubborn, sharp-tongued, serious, and defensive 16-year-old Kurosaki Hisoka. As they investigate each case, they draw closer to uncovering the conspiracies surrounding serial killer Dr. Muraki Kazutaka. Tsuzuki's bond with Hisoka grows stronger and more intimate, yet a dark secret about how Tsuzuki died continues to haunt him, refusing to let him find peace.

As Amon now runs wild again, destroying everything in its path, the chance of Akira regaining control over the entity grows more uncertain.

Instead of finding the legendary ninja, she encounters Yasaburou Manajiri, a wanderer being chased by "deathless ninjas"—mysterious warriors who can survive seemingly fatal wounds. Realizing they share a common enemy, they join forces to confront the ruthless lord and destroy the sinister puppets that conceal a terrifying secret.

Harry is hardly your typical American teen; he embodies the archetype of the isolated youth, with no friends at school, odd behavior, and intense anxiety that frequently borders on paranoia.

At the same time, sinister forces that recognize Harry's capabilities attempt to control and endanger him in disturbing ways.
