The Sabbath is a religion of the Monster Girl Encyclopedia world, its two fundamental tenets being to “impart the charm and indecency of tiny young girls” and “be devoted to pleasure like a monster” . Filled with loli supremacist monster girls, the religion is non-theistic, having neither a god nor any real supernatural connection at all. In fact it's one of the most technophilic and research-based organizations in the MGE, as they periodically hold "Black Masses" that are half magi-tech expo, half pedophilic orgy.
Under the supervision of the baphomet, the Sabbath's chief adherents are the witches and the familiars, but loli monster girls of any species are welcome. The Sabbath is very organized in its missionary outreach work, and maintains branch offices far and wide throughout the world. Much of the daily work of its members involves proselytizing unbelievers, and also "canvassing, holding periodic assemblies, developing spells and magical items, etc".
Today it's a global loli religion and probably one of the most organized monster associations there is, but the Sabbath's origins are quite different. It started life as the battle-magic division of the Demon Army, "originally a unit created to use magic in battle, and develop and test new spells and elixirs, but it ended up this way as Sabbath because baphomet ran it according to her own whims". This may account for its continuing interest in R&D, a hold-over from its original mission.
The Sabbath is headquartered in Royal Makai, and its head baphomet (sometimes referred to as the Baphomet) lives in the Demon lord's castle. The bulk of the Sabbath's rank-and-file are the witches, a lot of whom were formerly human sorceresses who volunteered for monsterization in the quest for "eternal youth" . The baphomets can grant youth permanently via the pride and joy of their magical research, the spell of pedomorphasis; or just let monsters try on a childish body for a little while, with a "one-day lolification elixir" . Aside from witches and baphomets, many monsters that are actually children (as opposed to just looking like it) are enrolled in the Sabbath by their mothers, in the hope of giving them a head start by getting lusty and pregnant as early in life as possible . To continue targeting children, the Sabbath operate childrens' clothing stores where garments are enchanted with pleasure runes; often with goat or dog motifs, "because the ruling baphomet is like the biggest dog lover ever".
As part of their missionary work, the Sabbath is currently pursuing cultural exchange with the Fairy Kingdom; teaching the innocent, childish fey the joy of sex and monsterization . Fairies easily become corrupted when exposed to monsters' demonic energy, and so after playing with child-like Sabbath monsters they are quite receptive to learning about a different "game" they can play with human men.
Despite the aggressiveness and assertiveness of the Sabbath's loli supremacy (to the point that they actively dislike busty, curvy monsters like the holstaurs), and the fact that the Sabbath only exists because the baphomets shirked their responsibilities in the Demon Army, it seems the Demon Lord and the lilims have no problem with the organization. In Baphomet Complex, a lilim even sets in motion a new Sabbath branch office herself through Lilia Flimlight.
A religious group lead by Baphomet who is one of the main leaders of the Demon Lord's army. Its doctrine is to be given to lust just like a monster, and to acknowledge the so-called “loli girls” with their immature bodies as supreme. They preach about the wonderfulness of “loli girls” day and night. All of the monsters in it, including Baphomet and her underlings the “witches” have the forms of young little girls. Other types of monsters belonging to the group also have their forms changed to look like young children, and special magic is used to stop them from growing. Besides the monsters, human men that love them little are also part of the group.
They're always soliciting human men day and night to get them to become “lolicon big brothers.” They tempt women by offering eternal youth and great magical power, transforming them into “witches.” They periodically have a gathering called “black mass.” It is said that they do various things there such as thoroughly indoctrinating the men and women who have gathered into their ideology and educating them, having witches unveil their familiars, holding feasts for witches without familiars and monsters without husbands, and unveiling newly developed lewd items and spells.
They have branches in every region of the world. The founder of every group is “Baphomet.” Furthermore, to put it more accurately, they are the “spell casting unit of the demon lord's army.” It seems the original duties they were charged with by the Demon Lord were engaging in magical combat, and developing and testing new spells and magical items.
The monsters have peculiar values that differ from those of humans.
Sabbath is a religious organization with activities based on those peculiar values that is run by “Baphomet (p.180),”  the champion of the demon realm who is the most important leader in the demon lord's army. They have young, small bodies, and they preach about the wonderfulness of little girls, and sex with them, to humans and monsters. It's a group of so-called “lolita supremacist” monsters who practice what they preach day and night. This time I'll introduce details about the demon realm's Sabbath based on materials provided by Sabbath Demon Realm Headquarters.
Sabbath has two fundamental principles:
“Impart the charm and indecency of tiny young girls,” and “Be devoted to pleasure like a monster.”
Their bodies overflow with charm, and by using them for sex as much as desired, they also impart the wonderfulness of a lewd, childish body to human men. Under the great childish leader Baphomet, all of the adherents, including her subordinates the witches (p.182), have assumed the forms of tiny young girls. They assault and have sex with human men day and night. In order to increase the number of “lolicon big brothers” who love sex with a childish body more than anything else, they do various activities day and night including: canvassing, holding periodic assemblies, developing spells and magical items, etc. Aside from “Sabbath Demon Realm Headquarters” which is ruled by Baphomet, the greatest leader of the demon lord's army who resides in the demon lord's castle, there are many branches in other regions, and it's an enormous organization. All of the branches of Sabbath are ruled by different individual baphomets. Each of these various branches has decided on its own uniform. Everything other than the crest of Sabbath placed on their chest is different depending on the particular branch, but all of them are designed to turn on human men, or rather, “big brother,” and ensure some vigorous love-making. Care is taken to ensure that the designs, while cute, are also licentious.
Other than the uniforms based on a goat motif worn by the witches featured in this book, there are also said to be witches who wear fluffy uniforms based on a dog motif which were designed that way because the ruling baphomet is like the biggest dog lover ever. Additionally, wearing the uniform isn't required. Wearing plainclothes while actively participating is also allowed, but they are recommended to wear something that accentuates the charm of their young bodies, causing big brother to get fired up and just hug them without thinking because it's so cute. By the way, the official name of Sabbath Demon Realm Headquarters is “Demon Lord's Army: Spell Casting Unit.” It was originally a unit created to use magic in battle, and develop and test new spells and elixirs, but it ended up this way as Sabbath because Baphomet ran it according to her own whims.
Most of the members who comprise Sabbath are witches who were formerly human women who transformed into monsters after receiving the baphomet's demonic energy within their bodies.
Being the baphomets' servants, they all totally adore them, and they're completely brain washed by Sabbath's doctrine. Along with the baphomets, they're responsible for the core of activities.
Other than the witches, there are various other races of monsters who are members. There are monsters who originally have the forms of young children that seek to learn how to seduce men better, or how to have even more enjoyable sex with the men who became their husbands using their childish body, and there are monsters who actually are young children who catch men and have sex while they're still young, becoming a prisoner to the pleasure of their immature body. Some are recruited by other members, and some become entranced with having sex in the form of a child after being transformed by using the “one day lolification elixir” that Baphomet invented. There is no end to the number of individuals who entered the faith for various reasons.
And since all the monsters who enter the faith are permanently transformed into young little girls by Baphomet's “spell of pedomorphosis (p.186),” the monsters who belong to Sabbath are all adorable little girls. Recently Sabbath has been making ties with the fairy kingdom (p.94) and the dwarves (p. 100), exchanging technology and information. Many dwarves and fairies participate in Sabbath to acquire sexual techniques for pleasing men using their own bodies. And let us not forget the male acolytes who form the core of Sabbath, along with the witches. They are commonly referred to as “big brother.”
Some of these “big brothers” already found a childish body attractive to begin with, and some of them were enthralled as a result of being assaulted and given a thorough taste of the childish body of a monster from Sabbath. The majority of them are “lolicon” who are brainwashed by the doctrine of Sabbath, adore the baphomets, and love the body of young children beyond all else. Those who aren't can also be found among the ranks of Sabbath, but eventually they will be. The monsters who belong to Sabbath, love their big brother more than anything else. They love being wrapped in the arms of a big brother who is way bigger than themselves and ravished. There is mutual attraction. They love to rape, and be raped.
Since their bodies are way smaller, what they love more than anything else is how much bigger big-brothers stiffy feels when they receive it in their tiny, narrow, childish vaginas. The objective of most of Sabbath's monsters is to find themselves their very own big brother, and spend every single day mutually enjoying indecent pleasure as brother and sister, or rather, husband and wife. Sabbath has an exemplar reputation among the mothers of young monster girls. Parents are pleased that their own cute daughters are catching men and enjoying sex so much while still young. They expect them to grow up to be even more lascivious by putting them in Sabbath.
And the black mass that is held periodically is the main activity out of everything. Black mass starts off with a spectacle that unfolds as human men and women who were canvassed and gathered by Sabbath are trained and thoroughly indoctrinated with pleasure into the pedophilic ideology of Sabbath. The adherents choose big brother, and women are made into witches. And then, after welcoming new friends, new techniques for more enjoyable sex in the body of a young child, and newly developed magical items with indecent effects are unveiled. The monsters of Sabbath can enjoy sampling new items and techniques with their big brother using their bodies right then and there.
After getting warmed up from this, the monsters' eagerly awaited orgy of pleasure begins.
The assembly hall where black mass is held is protected by the baphomet's demonic energy, so the monsters of Sabbath can just focus wholeheartedly on going at it with their big brother, and indulging in pleasure. Since the condensed demonic energy generated by the baphomet and many monsters having sex at the same time permeates the entire assembly hall, the bodies of all the monsters change, becoming even hotter, and even more sensitive to pleasure. Hence, the monsters are able to experience sex with big brother that is far more frenzied and pleasurable than ordinary.
By showing off the indecency of child sex to one another, they reaffirm the wonderfulness of a child's body. Besides that, they like to introduce, or show off and boast their favorite big brother by having everyone watch as they're being violated by him. The insane feast of young flesh continues until morning. Eventually, the monsters become covered in their beloved big brothers semen, outside and inside. They get tired and fall asleep. They breathe happily in their sleep while big brother carries them in his embrace as they leave the assembly hall together.
