Devil

This page details the Devil liminal race, for the Devil personality archetype featured in Monster Musume: Everyday Life with Monster Girls Online; see Monster Musume Online Character List. The Devils (デビル), known simply as the "Devil Race" (デビル系他種族) and their close relatives known as "Succubi", are a humanoid liminal race that sports tanned skin, horns, black sclera, bat-like wings, and tails that end in spade-like points. As a race, Devils are highly variable with such things as wing size, wing strength, horn size, horn count, tail shape, and even possibly physiological body type. Devils appear to come in both male and female sexes, though males as yet have only been seen as background characters and never referenced in dialog. Succubi may possibly be all female, or at least unable to satisfy their appetites via males of their own kind (given their specific focus on the fluids of human men).

General Information
It is difficult to get a general picture of Devils, as both the appearance and the behavior of a Devil depend on which subspecies it belong to. Devils are one of the few species that have magic, but the exact type of this magic or its strength also seems to depend on the respective Devil subspecies or even to be individually different. For example, Lilith seems to only have hypnosis, while Sitri can turn everything into chocolate, even though both are Lesser Devils. Lesser Devils and Greater Devils usually use their magic to play malicious pranks on others or to sow discord but this often brings them into conflict with the Cultural Exchange Between Species Bill. This is in contrast to the Elder Devils, who are generally calm and relaxed and don´t play pranks on others.

Succubi are an unusual female Devil subspecies, because they are characterized by the peculiarity that they individually look like Lesser Devils, Greater Devils and Elder Devils, even though they belong to the same species. They also lack the horns of regular devils. While it is not known if they can use magic as well, they are referenced as dream demons, though in context the reference is that Nightmares (Chapter 69) are the actual literal succubi and incubi of myth and the succubi devils thus may merely have the name rather than the power over dreams. They are best known for their high libido and enthusiasm in seducing men, to the point that it can be difficult to get them to follow public decency rules and when single will readily engage in an orgy. However, should they find a man they like Succubi remain extremely loyal, focusing all their lust on him, and outside of sex generally seem to be of a quieter, more sensible manner than some of their prankster relatives. It is unclear if male succubi (i.e. incubi) exist as the one reference to incubi thus far has been about how the nightmare race are the actual incubi and succubi of myth, not the Devil subspecies.

Physiological Attributes

 * Devil horns: A devil's horn shape is inherited, as well as the number of said horns. Normally, Devils possess one or two horns, but there have been individuals who have four horns.
 * However, Devils often get their horns become smaller via surgical means, as the horns can become problematic and interfering with daily life.
 * Succubi don't have horns, but in return they sometimes have tiny wings that grow out of the side of their heads. Examples of this are Pako-Chan and the Succubus from Chapter 78.
 * Devil magic: Devils are among the few species that are said to employ magic, with some skilled in psychic abilities such as hypnosis, which is how Devils typically sow discord, though this form of meddling is in conflict with the restriction of liminals harming humans.
 * Devil ears: A Devil's ears are capable of direction-focused hearing and are employed mainly for the purposes of extremely effective eavesdropping to make their mayhem more precise.
 * Devil tail: It is currently unknown for what purpose Devils use their tails for.
 * Devil body: Because a fully-grown Devil's body stops developing at a certain point, it is common to find out Devils are much older than what their bodies look like.
 * Devil wings: Although Devil´s have wings, they cannot fly as their wings are not fully formed and in fact the wings are an obstacle to daily life. However, this restriction could only apply lo Lesser Devils and Greater Devils, as the wings of Elder Devils may be airworthy due to their largest wing span.
 * Energy Consumption: Devils can detect and consume the life energy of biological beings to survive. However, it is possible that not all Devils and Devil subspecies have this ability, because although Saki has this ability, Lilith does not seem to have it.
 * Longevity: At least Elder Devils are known to have extremely long lifespans, and can live several centuries. However, nothing is known about the lifespans of Lesser Devils, Greater Devils and Succubi, as it's only pointed out that Elder Devils have the longest lifespans of all Devil species.

Lesser Devil
Lesser Devils (レッサーデビル) are devils that have the bodies of humans in their childhood. Lesser Devils have small wings and bodies that are comparable with children, even though Lesser Devils can be fully grown in actuality. Lesser Devils usually use their petite bodies to get away with affording things at children admissions rates.

They enjoy playing pranks, such as teasing and scaring others, and they can even use simple hypnotism technique. However, their physical abilities are similar to those of children, making them weak to counterattacks.

Greater Devil
Greater Devils (グレーターデビル) are devils that have the bodies of humans in their late teens. Despite the name, Greater Devils are not matured Lesser Devils, but rather their own Devil class. They enjoy dressing in human fashion and venturing into the city at night to play rather malicious pranks.

However, because their actual age is much greater than their apparent age, much like Lesser Devils, they can be out of touch with fashion trends popular among younger people.

Elder Devil
Elder Devils (エルダーデビル) are devils that have the bodies of humans in their adulthood. Appearing even older than Greater Devils, they are the voluptuous/highest class of Devil, and boasts the largest average wingspan.

Though it's unclear if it's because of their older apparent age, Elder Devils have the longest lifespans of all Devil species, and it's not uncommon for members to live several centuries. It might have to do with the their extremely long lifespans, but Elder Devils are quite calm and composed, and are beyond playing pranks.

Succubus
Succubi are a devil subspecies that can be similar in appearance to Lesser, Greater or Elder Devils but lack devil horns, possess a Womb Tattoo-like marking on their lower stomach, and possess a prominent interest in sex and all things sexual.

Religious traditions in human culture hold that Succubi live by sustaining themselves on “life energy" stolen through sexual intercourse and that repeated sexual activity with a Succubus may result in the deterioration of health or mental state, or even death. While whether this is true or not is unknown, Succubi culture is entirely rooted around the act of sexual intercourse; with the desire for sex, fornication and pleasure forming the basis of their cultural thinking and moral values, and as a result they are an extremely lustful and openly lascivious race. Not only are they physically beautiful, everything from their gestures to their voices will charm an individual and inflame lust. Their techniques for seducing and pleasing men and women alike are highly valued and are in some ways more effective than raw fighting abilities. They notably refer to sex as "eating", and well before they were specifically named as a race were shown as an example of a type of monster that feeds on "human bodily fluids" (in this case semen and sperm), suggesting that their intense libidos are due to both sexual desire and regular appetite. The ability of devils to absorb energy would further suggest that for succubi this energy is absorbed via the fluids they get from men during sex.

While it is true that Succubi have extraordinarily high libido, it is later revealed in Chapter 66 that they remain extremely loyal should they find a man they love, only having sex with him and never cheating. There is possibly a male variant of this subspecies, the Incubus, which are mentioned in Chapter 69, though the context of this mention (that nightmares are the incubi and succubi of myth) may have no relation to incubi existing as the male sex of succubi (since the succubi themselves have no connection to the nightmare race).

Despite their usually extreme lack of inhibition regarding sex, at least some succubi are seen to have a reliable work ethic and sense of responsibility (especially compared to lesser devils), one being hired to actually help catch guests breaking rules of propriety at Yukio's inn. Said succubus also waits until she is done with work to go out with a prospective lover.

Baphomet
Baphomets are a demihuman species with goat-like attributes in similar vein to Satyrs and Pan Fauns but with the addition of raven wings. Closely linked with occultism or outright Satanism throughout history, since the 1800's the species has been associated as members of the Hierarchy of Hell and as such their image has been imprinted as the official symbol of the Church of Satan. Baphomets are always crossed with pentagrams.

Trivia

 * The term "Fiend" is a catch-all name used to collectively refer in a nondiscriminatory way to Demons, Devils or Daemons as a whole, and the sub-varieties of each of those races.
 * Medieval Christian tradition use Devils and Succubi as an explanation for morning wood, wet dreams and unexplained pregnancies as it was believed that Devils and, particularly, Succubi visited people in the middle of the night to have sex with them. Additional sleep related ailments such as sleep paralysis and restless sleep were also attributed to Devil/Succubi visits. In the Monster Musume world the actual source of these myths are apparently the centaur subspecies called nightmares.
 * Cambions are a race of half-devils (half-fiends) born when a male devil mates with a human female. Similarly, Alu-Fiend's are an all-female race of half-devils born from a human male and a Succubus. A Tiefling, is a descendant of either a Cambion or an Alu-Fiend. There is no evidence any of these creatures exist in the Monster Musume world.
 * Lilith claims that it is so much more comfortable when there is some discomfort in the world; a lack of public safety. In her opinion, Japan is almost too safe for devils, although that does lower people's guard and makes it easier to spring bad stuff on them.
 * Succubi were first seen in the series in chapter 31 as one of the monsters invited to the Dating Pool that Yukio had set up. They would likewise cameo in chapter 49 when Kimihito is thinking about monsters that "feed on human bodily fluids" and imagines a succubus doing just that. They are first mentioned by name in chapter 40 when Lilith claims to be a succubus in an attempt to seduce Kimihito. However, the race would not truly be introduced and detailed until chapter 64 when a group of them starts stirring up trouble at Yukio's inn in their search for a mate. Another succubus would later in the same arc be hired as a bouncer for the inn to help lure out problem-causing guests.
