Two young doctors, the passionate and well-liked Osanai and the ambitious Tatsugaura, are both investigating the mysterious 'Monmo' disease, found only in one remote village, which causes bizarre bone deformation, making its victims take on a beastlike appearance before their deaths. Osanai, caught between the allure of his urban medical world and the rural peace offered by the remote village, does his best to help the victims retain their humanity in the face of a medical establishment which views them only as guinea pigs and oddities. Meanwhile, Tatsugaura schemes against Osanai and tries to infect his rival with the disease in order to gain fame from researching the results.

A serial-murderer is on the loose who just so happens to also be removing the hearts of his victims and taking them with him. His victims however, are not merely random humans as thought by the police. They are in fact, the past and present guardians of the gateway of the afterlife. On the day he is to be married, Detective Kanzaki, who happens to be on the case, discovers that his fiancé Mina has been murdered with her heart also missing. He also learns that the killers are Kudo, a geneticist, and his evil secretary Rei. The two are trying to obtain six hearts from the guardians so that they may call forth a horde of demons from the Gate of Rage and have their every desire granted. Only problem is, once they open the gate the entire world will be covered in darkness. Meanwhile, in the afterlife, Mina encounters Izuko, the Guardian of the Gate. Izuko gives her three options: Mina can choose to ascend to heaven and be reborn, she can choose to forever walk the earth as a ghost or she can choose to curse one of the living to death and as a result be cursed to descend to hell. Mina has 12 days to make her choice. - Wikipedia.

Aboard the Advenna Avis in 1711, a group of alchemists summon a demon in the hopes of gaining eternal life. The demon gives them an elixir of immortality and the method of ending their existence by "devouring" one another. Soon after, one among them begins to devour his companions. Realizing the danger posed by staying together, they scatter across the globe. Centuries later in 1930's America, a certain federal investigator tries his best to combat the rise of organized crime during Prohibition, send a particularly infuriating terrorist to Alcatraz, and catch an outrageous thief duo. Meanwhile, the transcontinental train, the Flying Pussyfoot, begins its trail of blood across the country. In 2002, a small group of the original Advenna Avis alchemists are on a journey to find the rest of their fellow immortals. However, there is one companion they did not expect to meet again. Seemingly unrelated events, from a sleepy Italian city in the early 1700's to a modern luxury cruise ship traveling across the Pacific, reveal themselves to be far more connected than anyone could imagine.

Six months ago, Karukozaka High School was sucked into the demon world, and in the ensuing chaos, only two survivors emerged: Nobu, who defeated the Demon Lord that took over the school, and Yumi, who possesses latent demon powers of her own.
