Rem Nighdrem

Rem Nighdrem is a Nightmare, who debuted in Chapter 69, where she asks Centorea for advice on finding someone to give nightmares to. While she appears shy and says it's normal for her species to cause nightmares in others, her trustworthiness remains skeptical.

Appearance
Rem is a tall woman with dark skin and light hair that is tied at the back of her head in a somewhat disheveled ponytail. She has black rings under her eyes and is wearing a light blouse with long sleeves. She also wears a black dress specially made for the lower body of a Centaur.

As a Nightmare, the most noticeable feature of Rem in her appearence is her headless horse's abdomen and pointy horse ears. Compared to Centorea, Rem has a rather modest bust size, but it is not known whether this is a personal characteristic or a basic characteristic of her subspecies.

Personality
Rem is shy, but also a bit inconsiderate when it comes to other people's feelings. This is seen as she gave Centorea nightmares, not caring that Centorea was already traumatized by the nightmares. In this respect she also seems to be a bit mischievous, since she gave Centorea many nightmares in a row, which was not previously agreed upon. It is not easy to judge if Rem cares much about the inconvenience of the people she gives nightmares to, which makes even Kimihito question whether she's a person to trust.

Rem also seems very proud of her affiliation as Nightmare. When Kimihito suggested solving the problem of finding someone Rem could give nightmares to by simply not doing it, Rem found the idea downright terrifying, since giving nightmares to others is an integral part of the Nightmares' culture and identity.

Skills and Traits

 * Hypnosis: With her pendulum, Rem can use hypnosis to put other people to sleep. As she explains in Chapter 69, this is a learned skill and not a natural skill of the Nightmares.


 * Nightmare Physiology:
 * Taste Buds: As herbivores, Centaurs generally have twice as many taste buds as omnivores (e.g humans), while omnivores have over twenty times as many taste buds as carnivores (e.g Lamia).
 * Normothermia: Like horses, Rem has a higher body temperature than Humans. Her's is 38°C (100.4°F) to be precise, which is the same as the average horse.
 * Centaurs Ears: A Centaur's ears are capable of reflecting the centaur's mood as they are able to move much in the same way as a horse's ears.
 * Cause Nightmares: As a Nightmare, Rem is able to cause other persons nightmares. If the person is not asleep, Rem can put them to sleep beforehand using hypnosis.
 * Sense of Smell: Due to their equine biology, Centaurs have a sense of smell that is 1000 times greater than that of a human.

Possession

 * Pendulum: Rem has a pendulum which she uses to put other people to sleep through hypnosis.

Zoological Classification
Nightmares are a demihuman subspecies of Centaur that can enter the dreams of sleeping individuals and create nightmares, however if the individual is awake they have to use hypnotism to put them to sleep.

Trivia

 * In their debut chapter Rem is simply called "Nighdrem". In contrast to the other Centaur girls in the Centorea Act (except Cheron), Rem's first name instead of her surname was not revealed before the omake of Volume 17.
 * After Lilith, Rem is the second character in the manga series that can use hypnosis, but in contrast to Lilith, Rem uses a pendulum because her hypnosis is a learned skill and not a natural skill of her species.
 * She considers "thinking about what can cause nightmares" as her hobby.
 * She recently has gained the problem of having a lot of nightmares herself.
 * Her last name is probably a pun on the word, nightdream and the first, REM which stands for rapid eye movement that is associated with sleeping state.
