Nothing ever happens in the village of Sotoba. In fact, it is viewed as nothing more than a hick town by its most outgoing and fashionable resident, Megumi Shimizu. She wants nothing more than to live in the city, far away from the villagers and their outdated ways of thinking. So when a new European-style house is built on a hill in the village, Megumi believes its residents must be cultured and refined, so she decides to pay them a visit.

However, Megumi doesn't return home that night. After a grueling search, she is found the next day, weak and anemic, with strange bite marks on her. But Megumi is just the first victim in what will soon become an epidemic in Sotoba as the bodies start piling up. The village doctor Toshio Ozaki, along with the priest Seishin Muroi, the loner Natsuno Yuuki, and the Tanaka siblings Kaori and Akira, begin investigating the strange deaths. But the answer to their predicament may be more than any of them can handle, for soon the dead could outnumber the living.

Samamiya, Akaza

Bloody is a vampire unlike any other that Ichirou Rosario di Maria has met. He has red hair and red eyes, refuses to drink blood or hurt humans, and cannot die even when exposed to sunlight. The two meet when Bloody rescues Ichirou from a group of vampires who desire the coveted "Blood of Maria" running through his veins—its delicious scent lures in vampires like a siren call, which has caused Ichirou recurring problems. After defeating the low-level nuisances, Bloody begs Ichirou, whom he calls "Maria," to finally end his interminable life.

At first, Ichirou is skeptical that Bloody is as harmless as he seems, and does not know why he would be able to successfully kill a seemingly immortal vampire. As it turns out, Bloody has him confused with another "Maria"—Isaac Rosario di Maria—a famed priest and exorcist who lived four hundred years ago. Ichirou inherited the cross-shaped rosario that his grandfather carried, and should possess the same ability to exorcise even the strongest vampires—such as Bloody—but is unfortunately unaware how to call upon his dormant powers.

Determined to survive the repeated attacks on himself, Ichirou makes a deal with Bloody, who he renames "Mary"—until the day comes that Ichirou can fulfill Mary's death wish, the vampire must do everything he can to protect this single human.

Susumu Nakoshi is a middle-aged man who spends his days between a lavish first-class hotel and a park full of homeless people. One day, an eccentric young man approaches Nakoshi in search of subjects willing to partake in trepanation—the procedure of drilling a hole in the skull. 

This mysterious person claims that Nakoshi is the perfect man for the experiment. Initially rejecting the offer, he doubles back on his decision after his car gets towed off. Nakoshi agrees to let Manabu Ito, a 22-year-old medical student, drill a hole in his skull in exchange for 700,000 yen. The procedure bears no results at first, with Nakoshi showing no abnormalities. This normalcy comes to an abrupt end, however, when Nakoshi begins seeing the homunculus in every person. With his perception distorted, how will Nakoshi face these homunculi?

Lonely high school student Kei Kurono isolates himself out of a growing cynicism toward his fellow man and the cruelty they are capable of enacting. One day, while waiting to take the subway to school, Kei's classmate Masaru Katou leaps onto the tracks in an effort to save a drunk man. Driven by an uncharacteristic desire to rescue someone else, Kei follows Katou down into danger. While successful in saving him, the two boys are killed by the train.

Kei wakes up beside Katou in an apartment full of strangers and furnished by a giant black orb with a glass-like outer surface. After finding out that everyone in the room has recently died, words appear on the black ball tasking them with killing a strange creature. The ball equips Kei and the others with power suits and mysterious guns before sending them off to collect this bizarre bounty.

Although Kei discovers the mission to be far more deadly than originally suspected, he manages to survive. He is teleported back to the apartment where he and the other survivors are rewarded point values according to their actions in battle by the black sphere, which a fellow survivor says is called "Gantz." Despite his death earlier that day, Kei is granted the ability to return to his daily life with one condition: he can be uprooted from his day at any time and summoned back to the apartment, where Gantz will task him and other recently deceased with the assassination of another target. 

While Katou dreads the inevitable return to Gantz, Kei finds himself living for the sole purpose of carrying out these missions. Thriving in the heat of battle and learning to care about himself and his comrades, Kei faces escalating monstrous threats that begin to bleed out into his normal life outside of Gantz.

Seventeen years ago, mysterious immortal soldiers known as divine warriors appeared on the battlefields of Africa. These life forms later became known as Ajin, or demi-humans, and were considered to be one of the greatest discoveries of mankind. The government declared their existence to be compatible with humans; however, it is rumored that they instead offer bounties for captured Ajin to secretly perform inhumane experiments on these rare beings.

Kei Nagai, an apathetic high school student, is studying to become a doctor and only wishes to live a normal life. However, this simple dream is shattered after he suddenly gets into a deadly traffic accident. Revived at the scene, he is immediately labeled as an Ajin by bounty-hungry witnesses. Unable to understand his immortality or prove his innocence, he starts to live his life on the run and fights for survival. He barely escapes the government's reach when a group of anarchistic Ajin contacts Kei, asking him to join their forces to retaliate against the government. But who is Kei's real enemy, and which side will he take when it comes down to humans versus Ajin?
