Monster Girls



Monstergirls, also known as mamono or sometimes just monsters, are the stars of the Monster Girl Encyclopedia and its many subordinate publications. While they come in a cornucopic variety of shapes, sizes, and dispositions, in the Monster Girl Encyclopedia world they are all united by an overwhelming love of sex, with supernaturally beautiful bodies to make sure they get it.

Decried as the enemy of mankind by the Order of the Chief God - the theocratic world-church to which the vast majority of humans belong - monstergirls' inhuman looks and questionable dating practices means they really are viewed with dread by most of the other races of the world, even though for the most part their intentions aren't any more sinister than giving the men they capture a really, really good time.

General Features
The monstergirls were created as magical hybrids, combining the traditional blood-drinking, skull-crushing monsters of the age of the Former Demon Lord with the sultry, seductive, and sexy succubus race. What popped out the end were creatures that still walk on eight dagger-tipped legs or a million writhing tentacles, but at the same time have rockin' tits and a literally irresistible sexuality. Their monster heritage endows them with superhuman strength and an instinctive urge towards wanton mating, but it also means they have great difficulty with the word "no" - meaning that encounters with human males regularly end in hot, sticky reverse rape.

The habitats of monstergirls are as varied as their forms. Some remain in the haunting grounds of their monstrous predecessors: barren wastelands, deep forests, and spooky graveyards. Others make their homes deep under the sea or high on the mountaintops. But, once the monsters were gifted sexy forms and divested of their propensity to murder everything they set their eyes on, inevitably there are some humans who are happy to live alongside them in mixed communities. Here monstergirls are generally more placid, and prove enthusiastic workers in roles from high-class prostitute to... err... other varieties of high-class prostitute.

As the above suggests, not all monsters are violent in their endless pursuit of coitus; different species' behaviors run the whole gamut from one-sided kicking and screaming violation through equitable human-style courtship all the way to enticing men to rape them. Still, whatever method they use, if a monstergirl spots you, you are unlikely to come out of the encounter with your pants intact. Not even gender will necessarily save you - many monsters enjoy yuri raping women almost as much as they enjoy raping men. So while monstergirls won't club you to death and suck the marrow out of your bones like their progenitors did, if anything they have become more dangerous to other races now that sex has been honed into a superweapon.

A Succubus' Plan: Monsters become Monstergirls


When the world was created by the original Chief God, monsters were slavering, shambling horrors that fed on the flesh of man. The history of the world is an eternal cycle of rise and fall: monsters pillage human civilization when it is weak, and are pushed back to their dark lairs when it is strong. It was a yin-yang balance that ebbed and flowed for uncountable eons... until one being - not a god or even a human, but a monster succubus - had an idea. Succubi were odd creatures by the monsters' standards, as they fed on semen instead of blood, so their lives were dedicated to pleasuring human males rather than ripping them to pieces. And the succubus' idea was: if all the other monsters were like succubi, then there need be no more endless slaughter.

It was a crazy utopian pipe dream which actually could be - and, in the end, was - realized. The succubus teamed up with (and married) a sympathetic human hero, and went on to have herself crowned as Demon Lord, the demigod of the monsters. Using the magical power of that office she cast a great enchantment, which channeled her succubus traits into all the other monsters in the world - and thus monstergirls were formed.

It is not a solution without teething problems. Major, potentially-wipe-out-all-sentient-life-in-the-world problems. The most obvious one is that the gods are not especially amenable to upstart mortal sex-demons unilaterally editing the whole metaphysical character of their world. By this point, however, the Demon Lord had grown strong enough that (with her husband's help) she could actually hold her own in battle against the Chief God. Astonishingly thwarted in her attempt at a decapitation strike, the Chief God has retreated to Heaven and settled back into a long game of holy war, directing her mortal and angelic servants to battle the monstergirl menace wherever they find it.

A more slow-acting but probably more dangerous problem is that the Demon Lord's monstergirl-making enchantment didn't actually do what she'd intended it to. The sexy, pro-active monsters are all according to plan, but the eventual product of all this sex turned out to be only female children. Monstergirls give birth to more monstergirls, whereas the Demon Lord had expected an issue of monster daughters and human sons. Obviously, this is a feature that leads first to demographic imbalance and later to total extinction.

Book Information
There are more passages in the Monster Girl Encyclopedia books that describe monster's general features than any other topic. In addition to the few below, see especially All for the Sake of Sex, Races of Monsters, Encounters with Monsters, Fundamentals of the Monsters, etc.
