This is a warning. Due to the foolish acts of humans, a deadly virus has spread. Unfortunately, the human race will perish.

–The annoucement

One day, a mysterious virus appeared that seemingly killed all humans over the age of thirteen, and vampires suddenly emerged taking the surviving children underground.

A few years later, Yūichirō Hyakuya and Mikaela Hyakuya live there and give their blood. Yu hates the vampires and gets into trouble with them, but Mika gives his blood to Ferid Bathory in exchange for good food and anything he might want. That night, they eat the curry Mika earned and decided to escape.

During the attempt, Ferid slaughters their entire family. Yu is the only one to escape having to leave Mika behind. He flees to the surface and runs into Guren Ichinose, who calls Yu a guinea pig and says he will use him to defeat the vampires.


List of characters in order of appearance:


As an aircraft can be seen flying over a city adorned in lights, as people are seen going about their days; walking through the city on chilly winter night. Among this crowd of humans a duo of adults can be seen walking side by side, until one of them seemingly vanishes leaving the other confused. Taking in her surroundings, the girl looks around for the man only to see him lying on the ground. Beginning to approach the latter, she suddenly clutched onto her chest, gasping for breath eventually joining the other on the ground, coming face to face with an unexpected death. The other adults can be seen following suit as a car crash occurs, and the plane crashes on to the ground; all of them now having collapsed with the society the world had known until today.

Krul Tepes leading the vampires to enslave the remainder of humanity

Among the renaming ashes of a big chunk of humanity, third Progenitor: Krul Tepes, is leading a her faction of Vampires, as she strides down the streets of Tokyo, taking in the aftermath of the events that had just taken place.

Through the chaos emerging due to the sudden disappearance of adults, group of kids lead by Mikaela Hyakuya can be seen running through the streets, with the animals such as dogs barking, clearly terrified too. Seeing an active source of light Yūichirō Hyakuya comes to a halt, only to witness a man vomit out blood and pass away right in front of him. As his mouth falls open in shock, he sprints to catch up with the others.

Continuing to run for their lives, they can hear an announcement beginning to explain what exactly had happened. It spoke of a warning to the rest of the human race, blaming their foolishness for the spread of the virus, saying that it was only inevitable that the entire race would perish.

Mika, Yu and Akane with other orphans

Directing them to a play room Mika slams open the door only to see the orphanage director lying on the floor, as Akane Hyakuya points out his condition. Taking in the situation, Mika tells Yu to look after the others as, as they are trying to reach out to the director. The announcement goes onto say that children under the age of 13 would not be infected by the virus, confirming that they, the direct unit of Krul would start "protecting" the children in the district. Watching a shadow go across his face, Yu moves his gaze along to window where a vampire can be seen shattering the glasses with extreme ease, as he walked in. Much more terrified than, the kids now huddled together in a corner. As the door opens once again, another vampire walks in.

On the highway, above the river that now looks like it's flowing rich with blood, a number of green trucks can be seen carrying children, Yu and Mika among the lot. Sitting close together, Yu looks down at a smaller boy, who trembles against his touch.

The children lining up

Four years later, over the eerie scene of the Sanguinem, a young children are seen forming lines, walking out of a tunnel like system, waiting behind some sort of a barricade. Moving ahead, Yu can be seen confirming his identity and moving forward in line waiting there for Mika, who also had to confirm his identity. After he's done, he can be seen walking to the same place as Yu as they venture up a flight of stairs.

The girl getting her blood drained

A girl can then be seen, sitting down as a pipe is inserted into her neck, drawing her blood. Looking weaker, Yu walks with his hand around Mika's shoulder, after which the latter can be seen sitting down on a flight of stairs as he drinks a liquid from a bag. Clearly not pleased with the taste Mika scowls as Yu grunts, crushing his packet. Concerned, Mika asks Yu if he would be drinking it or not, as Yu simply sits down beside the other, looking at the drink in hand. Yu affirmed that could not drink this "disgusting piece of crap". Mika looked at the other as he said that Yu's palette was extremely gourmet, as the man in question looked away in retaliation. Yu goes onto say that Mika should stop doing everything that they said. Face going grim, Mika stands up and to say that it wasn't that bad. Yu, taken aback exclaimed and asked the blonde if he was serious. Mika plainly said that they wouldn't be killed in there and they could live with their family; asking Yu about that not being enough, as he proceeds to toss the packet in the bin. Egging on the argument, Yu said that he was not their livestock, throwing his packet at Mika (who easily dodges) when he told him not be so stubborn.

Yu's anger at vampires results in being held over a ledge

As the packet falls on the ground two children could be seen drawing on the floor. Noticing the situation Yu calls out as a pair of hooded vampires approach and walked straight into the children; one stepping on one child's hand while the other kicks the second out of the way. Enraged, Yu attacks one of them, who dodges with extreme ease as Mika apologizes on the latter's behalf trying to explain how Yu is "messed-up in the head" as he tried to think of a possible excuse for the Yu's actions. As Yu still continues struggling, the vampire now holds Yu over the edge of the walkway, ready to drop him at any given moment. Mika visibly panics.

Mika cheerfully greets vampire noble, Ferid

As Yu's life hangs in the balance, he looks down at the clearly long fall, as the vampire puts his hand out; fully concentrated only to be disrupted as seventh Progenitor and noble; Ferid Bathory as he makes his grand entrance, greeting the lot. The vampire holding Yu over the ledge finally tosses him back onto the walkway before taking his leave as the latter began gasping for air in a coughing fit due to being held by his neck. Yu, now curious questions if Ferid was a noble, only to be proven correct as Mika cheerfully runs up to him greets the vampire, calling him Lord Ferid. Walking closer, Ferid greeted Mika in return, asking if everything was okay, and Mika simply said it was nothing and one of his family members was just causing some trouble, to which the former told Mika that he had too much to worry about. Moving in even closer, Ferid strokes Mika's cheek asking him if he would like to come by his mansion tonight as Mika nods, saying yes please. Ferid calls him a "good boy" saying that he had delicious blood and was always very much welcomed there. Now looking over at Yu, he asked if he would be joining them too, beginning his reply with a clear no, Mika cuts the former off by saying he's too shy, and maybe he could tag along next time. Ferid shrugs it off saying that was too bad.

Mika and Yuu talking

Now pulling Yu along, him and Mika can be seen walking down a corridor, as Ferid lets out a soft chuckle and walks away. Walking side by side, Yu had asked Mika about why he had apologized, saying that he was about to kick that guy's butt. Mika sighed and looked at Yu, looking extremely used to this, saying there went the latter with his nonsense again, additionally saying there was no way a human could beat a vampire. Yu managed to retaliate by saying that they'd never know until they tried. Mika again said that it was not possible, telling Yu to not overwork himself, additionally saying it was an extremely close call. Stopping in his tracks, Yu turns back to Mika asking the latter if he and Ferid knew eachother, and he indirectly responded by asking if it was important, additionally saying that if her offered his blood to thee noble, he would give the blonde whatever be wanted; including good food and to survive in a place like this, they had to use their heads and be smart. Yu now walks up to him giving the other a gentle punch on his face and walking away. Holding his hand against his face, he asks Yu if there was something he wanted, but the latter simply cut him off before be could finish, saying a no. Mika is now left staring at Yu as the other walks away.

Asking why he isn't with Mika, Akane reminds Yu his family are waiting

As the day turned to dusk, Akane finds Yu lying down, pouting on a rooftop. Perking up, she states that Yu was there again; implying that the latter had already been there before. Carefully walking down the roof, she begins asking Yu about what he was doing there and why Mika wasn't accompanying him. As Akane takes a seat to him, Yu sits up; still sporting the grumpy pout.

Still not making eye contact, he said that he wasn't with "that idiot", which genuinely surprised Akane, making her ask Yu why he was upset. Yu told her to be quiet and not come near him, to which Akane responded by moving closer and asking him why not, stating that they were a big family after all. In retaliation, Yu told Akane that he didn't have a family, finally making eye contact with the girl. Now forming a pout of her own, she contradicts Yu's statement by saying that he did have a family; the director had told them so. Sighing and looking into the distance, Yu said that it was stupid as he begins to remember his time at orphanage.

The director introducing Yu to the other orphans

During his flashback, Yu can remember the director introducing him to the rest orphans, saying that he was a new family member, and that they should all befriend him. Mika was the first to respond, waving his hand as Yu looked away in the other direction.

Yu goes through his bag of stuff, as Mika comes up to him with two other orphans, introducing himself. He goes onto saying that he was orphan, just like Yu, but he had a big family now and Yu was now a part of it. Yu simply said that concept of "family" was stupid, cutting Mika off and leaving the latter confused.

Mika extending his hand

Talking about his past, he said that his father had tried to kill him and his mother had screamed about Yu being a demon child, killing herself after; resulting in him ending up in the orphanage. Getting angry, he tries to explain what a family is to him, only to be cut off by Mika who extends his hand. Mika stated that he thinks that must have been difficult, but starting today, they were his new family just as the flashback ended.

Still looking into the distance as bells ring in the background, Akane tells him that they should get going now as Yu snaps back into reality. Telling him everyone was waiting for Yu to eat dinner, she goes back up the way she came, telling the latter to come straight home. As she walks away, Yu sighs, lying back down again.

He comes in, and Akane is preparing curry for all of them. The children are all so excited that they began saying its their birthday. Akane reminds them all to be sure to thank Mika later. The children dig in, but Yu refuses to eat, knowing what was involved in getting it.

That night, Mika returns quietly into their house, Yu hears his creaking on the floorboards. They chat briefly, Yu says he will give his blood next time but Mika insists that no one wants his nasty blood. Mika breaks into tears for a moment when he tells Yu that Yu gives them hope. Then, they go back downstairs, and Mika serves some curry for himself. He puts some of his plate into a separate bowl for Yu. Yu insists he does not need it, but Mika already realized Yu did not eat any earlier. He gives Yu the gun he stole from Ferid and tells Yu to build up his strength. They chat, and Mika suggests that they escape from this world.

The orphans decide to escape Sanguinem where they live as livestock

Akane hears them and comes down the stairs to see what they were doing. Excited, Mika pulls out the map that he stole and tells Akane to wake everyone up.

The children sneak through the sprawling underground city. At one point, a vampire guard hears them, but they hide in a grate and managed to avoid detection.

The group manage to reach the exit

They come into view of the exit of the city and walking with the assurance that they have made it, Ferid steps out from beside the gateway and basks in their expressions of shock and disbelief. He comments about how he loves this game and then proceeds to slaughter the children one by one.

Yu is able to use the gun against Ferid

Akane is murdered, leaving only Yu and Mika alive. Mika takes the gun back and charges at Ferid, who pierces Mika through the chest with his hand. Mika raises the gun at Ferid's face, but Ferid slices off Mika's arm. Mika tells Yu to run, however, Yu catches the gun and shoots Ferid in the head.

Yu holds a badly injured Mika

Yu cries as Mika falls to the ground. Pulling Mika to him, he tries to drag Mika to the exit but falls. Mika pushes him away, not wanting them all to die as other vampires have arrived. Crying and covered in Mika's blood, Yu races and stumbles as he escapes the underground.

It is night as he runs outside into the snow, but he can see a ruined human city before him. He struggles and is eventually come across by Guren Ichinose and his aides, Shigure Yukimi and Sayuri Hanayori.

A man called Guren was expecting Yu

Guren calls him a guinea pig of the Hyakuya orphanage and tells him he will be useful for fighting the vampires. Yu cries and says that's what he wants. He hugs Guren so tightly that he eventually knocks Guren over leaving him baffled.

Four years later, 16-year-old Yu walks the ruined streets above ground in his military clothing.
