Vampires

Vampires are human-like creatures who suck the blood of humans. They are a focal aspect of Call of the Night.

Description
Vampires are preternatural beings who like to suck the blood of humans during the night.

All vampires possess extreme physical qualities and supernatural abilities:


 * Super strength: Vampires are known for their superhuman strengths, they can tear down concrete walls and floors with bare fists and slice apart another vampire's arm singlehandedly. Their kicks are able to send another vampire flying away.
 * Super speed: It is nearly impossible to see a charging vampire with the naked human eye, as their pouncing speed exceeds the limits of human sight. Only vampires are able to keep up with their own kind in face-to-face combat, but experienced people like Anko Uguisu can dodge and outsmart vampires. However, their flight speed is much slower than their pouncing speed.
 * Enhanced sight: Vampires have dynamic sight that allows them to see other vampires' high-speed movements clearly. When one becomes a vampire, sight issues like myopia is also improved. Note that vampires don't have night vision.
 * Regeneration and resistance: Vampires are able to heal small wounds rapidly, and sucking blood allows them to quickly mend large wounds， even penetrating injuries. Despite healing abilities, they also have hardy bodies, able to remain conscious after a straight shot in the head or with a gaping hole in the chest.
 * Flight ability: Vampires possess the ability to fly airborne. This flight is not based on physical powers like wings, but more like a magic that makes the vampire weightless and able to maneuver in the sky. Usually, one has to take a leap off a solid thing as a fulcrum to start flying.
 * Intangibility: Vampires can phase through structures or let objects go through them. This ability is not as easy as it may appear, as one has to forage through unknown structures while carefully controlling the body part that phases through. If one terminates the ability while a body part is still phased with a solid thing(e.g. arm passing through a wall), the body part will be expelled by the object, thus be broken apart. If used wisely, a vampire can use its phased body part to dodge its opponent's attacks or trap the opponent's weapons in its body.

They take a human form, however there are distinct differences between them and normal humans. Vampires can be told apart from humans by the following features:


 * They have no pulse;
 * They possess unusually long and sharp canine teeth, designed to pierce skin to suckle blood;
 * They can also grow long, sharp nails, although it seems that this trait can be concealed at will;
 * Their reflections cannot be seen in mirrors;
 * They are noted to all be exceptionally beautiful by human standards, which is an evolutionary trait evolved to efficiently make humans fall in love with vampires, as noted by Kabura Honda.

Vampires do not age as regular humans do, often looking youthful in appearance, and are also able to heal wounds that they have been afflicted with very rapidly, meaning that they're presumably immortal and thus immune both to death by old age and death by bodily harm. Due to the fact that most vampires have lived for a very long time, they often quickly forget their memories from when they were human.

Vampires have a reflexive and innate thirst for human blood, and if they're deprived of it for long enough they may begin to lose their sense of reason or even die. However, blood doesn't necessarily always taste nice to vampires. Nazuna Nanakusa notes that it tastes the best when it's sucked from a human between the time they're beginning to fall asleep to the time they actually fall asleep, and the blood of people like Kou Yamori also tastes unusually good.

Not much is known about the actual history of vampires other than the fact that they seem to have existed unknown to humans for a very long time.

Weaknesses
Anko Uguisu has noted several weaknesses vampires have that can be used to kill them. Even if one does not possess fatal weaknesses, it is definitely not invulnerable, injuries like broken spines and broken neck will immobilize it the same, and attacking weak spots like eyes will also deprive it of its senses. Pain is not relieved even if one is immune to damage, so vampiric combat is often accompanied by agony.
 * Human Memories: If a vampire comes into contact into something that was important to them when they were a human, it has the potential to kill them. The deeper the emotional bond the greater the effect.
 * Lack of Blood: Vampires die if they do not ingest blood for 10 years. The more time they spend without blood, the weaker they become, sometimes reaching the point at which they become almost delusional and lose all their senses other than their thirst for blood.

Servants
Vampires are able to turn other humans into other vampires if two conditions are met: the vampire is able to drink the human's blood, and the human is in love with the vampire who intends to convert them. Vampires who are created this way are referred to as "servants", and often act as subordinates of vampire who converted them due to the fact that they are infatuated with them.

A vampire can have multiple servants. This amount has no known limit, but with some exceptions like Kiku Hoshimi, most vampires have around five or less.

Birth
Vampires can also be created as humans are if at least one of their parents is a vampire themselves. Vampires created this way don't seem to lose any of their additional vampiric abilities or aspects despite having human blood.

After being born, they will grow to physical adolescence within a very short amount of time, however their brains still require regular socialization and they do not hold any innate knowledge despite their rapid maturation.

Nazuna Nanakusa is the only known vampire to have been born this way.
