Devil

The Devil Race (デビル系他種族), known simply as just "Devils", 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.

Culture
Mischievous by nature, Devils seem to find the suffering and frustration of others to be hilarious and will actively attempt to cause drama or trouble for their own entertainment.

Physiological Attributes

 * 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.
 * 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.
 * 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.
 * It is currently unknown for what purpose Devils use their tails for.
 * 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.

Lesser Devils
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.

Greater Devils
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 Devils
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.

Trivia

 * Devils are the first liminal species that does not seem to have a standard race as a default, though Lesser Devils can be considered as the "default" Devil race.
 * Life energy is often considered the most potent form of energy, with a being's own soul/spirit being the apex of the most ideal energies to absorb; however, only the most malicious entities will endeavour to absorb a being's soul for their own sustenance. Those that do, however, will often either absorb copious amounts of life energy from the host over an extended period of time until the soul/spirit beneath is exposed for them to absorb or they will induce the host into an increasing sexual state; during which the being's body will be fooled into emitting steadily increasing levels of life energy in preparation for mating with the malicious entity. The output of life energy will continue up to orgasm; during which the host's life energy output explodes exponentially and their soul is exposed for the entity to absorb. The entity will then latch onto and siphon out the soul either by forcibly coercing it out of the being via their mouth, nipples or genitals during orgasm or by inserting an appendage such as a tentacle into the being's body and siphoning their soul/spirit through the appendage into their own body. The absorption of the soul/spirit instantly kills the being or otherwise renders them "undead".
