Entropy's Servant

Part 1 character summary

Navillus (Grand Slime)
Notable skills: [Omni-digestion] [Long-range control]

One of the 5 Demon Generals, Navillus is made of slime, an odd shade of turquoise. She has a hard time maintaining a human form, so it's a bit wobbly, but generally, whenever she's taking a human form, she looks well-endowed and fairly charming. She's completely monochrome, though. Because of her semi-transparency, even shadows are hard to see, after all.
Of course, there are no reproductive organs on her human form. As such, she wears no clothing.
Her thought processes are primitive and often focus on food, and because of her race, she can eat practically anything. Despite that, she might occasionally come up with a decent plan exactly because of her simple thought processes.
As she is a slime, she can take on any form she likes. She can even separate her slime into several pieces she can control using the [Long-range control] skill.
To her, Astaroth is her owner, as well as the provider of food.
As she's a perfect garbage disposal and often cute to boot, she has a favourable relationship with practically everyone in the castle.

Lilith (Arch-Devil)
Notable skills: [Hell magic] [Devil Shamanism]

One of the five Demon Generals, Lilith has purple skin and hot pink, shoulder-length hair and her face is covered in strange markings. As she is a Devil, she has two horns on her head, and the tail sprouting from her lower back is tipped with a heart. She wears a sleeveless crop top, a pair of hotpants and boots long enough to reach halfway to her knees. Due to her 'assets', this outfit can be stimulating.
Lilith can easily be described as 'perverted', and she will often be found reading books that are either suggestive or outright pornographic in nature. She enjoys the sight of beautiful men and women alike, and due to her personality, skills like [Increase Charm: Devil] have an increased effect on her. She has a tendency to be slightly impatient, sneaking bites of food before the meal begins.
Despite her generally carefree personality, she bears a grudge against Yxon, the Shield Hero, and by extension the Goddess of Light, for sealing away her entire tribe, and when it matters, she shows significant magical talent and a capacity to become incredibly angry if not controlled.
Charlotte, another of the five Demon Generals, is almost like an older sister to her, and capable of consoling her when no one else can.
To Lilith, Astaroth is her life saviour, but she holds no particular romantic interest in him--it is always either a joke or an involuntary, skill-based bodily reaction.
Incidentally, if she were to find someone she takes romantic interest in, the odds are high her regular behaviour would become more 'decent', since she'd feel bad for the other party otherwise.
In her past, when she lived with her tribe, it seems there was a mysterious black-eyed man who taught her about the Goddess of Darkness. At some point, for unknown reasons, he stopped coming.
She's moderately popular in the castle, and many Demons have made passes at her. So far, despite her personality, she hasn't reciprocated any, since she'd like to save that for her 'special someone' she hasn't met yet. As a result, she'd even refuse Astaroth.

Charlotte (Vampire Princess)
Notable skills: [Bloodworks] [Heiress of the Vampire Kingdom]

One of the five Demon Generals, Charlotte has white, wax-like skin and deep red eyes like oceans of blood. Her black hair flows to her hips, and she takes meticulous care of it. Unless she's making an effort to hide them, her fangs are usually visible, protruding from between her lips, equally colourless as her skin. She wears 'gothic lolita'-style clothing, frilly clothes which are mostly black with some white, designed to cover most of her skin. The only part of her skin which is visible beneath her neck is her right wrist; The rest is covered, be it by her knee-length skirt, her thigh-high black socks or her elbow-length gloves. Despite her danger, she looks and sounds like a little girl.
Charlotte places a large amount of importance on 'manners', aiming to conduct herself as much as possible as a 'proper lady' should. Despite this, her fighting style often involves hiding herself in the shadows or facing her opponents head-on in a battle of speed.  Due to her [Bloodworks]  skill, as long as her opponent has blood of some kind, any victory in combat directly increases her fighting strength.
Because of her personality, despite her appearance, she acts as an 'older sister' figure to Lilith and occasionally Davna, though because of their proportional ages to the age of maturity, she's stricter towards Lilith. She's having a hard time drilling the concept of 'manners' into Lilith's head.
A Vampire's evolutionary path could be described as unusual--the more they evolve, the higher their 'court rank' becomes. For example, a Vampire Marquess or a Vampire Marchioness is far more powerful than a Vampire Baron or a Vampire Baroness. Only Vampires born of royalty can evolve into Princes or Princesses, however. Theoretically, a Vampire Archduke is more powerful than a Vampire Prince, but a Vampire Archduke can no longer evolve, whereas, given the proper circumstances--legitimacy to the throne and the death or abdication of the previous monarch--a Vampire Prince could become a Vampire King, and a Vampire Princess a Vampire Queen.
Charlotte's view of Astaroth is unknown, but she's shown expressions of resignation whenever the latter has displayed his tendency towards sadism, his doting on the Goddess of Darkness or expressions only a villain would make. It can be assumed she thinks of him as slightly troublesome, at the very least. Given she continues to serve him, she probably does not dislike him.
In the castle, Charlotte is well-known by nicknames such as the 'queen of good manners' and 'collective big sister'. She's well-respected, especially by the vampires.
Does she know the mysterious black-eyed man...?
