Monster Girl Encyclopedia

A NSFW encylopedia fleshing out a setting of monstergirls written and impressively illustrated by Japanese hentai creator Kenkou Cross.

The Setting

The long and short of it is simple. A Succubus has married the human Hero and together they defeated the old Monster Lord, god-like ruler of all monsters. Taking the throne for herself, the Succubus has enacted a plan to bring about her vision of peace upon the world: transforming all monsters into lusty monstergirls, known in universe as mamono, and setting them out to score themselves human husbands.

The Factions

What are the big groups running around in the setting? Well, so far, these various fuckers here.

Monster Lord

The aforementioned Big Chief Succubus, her human husband, their daughters, and pretty much every freaking mamono in the world. Want to bring about peace between humans and monsters by making human man/monstergirl relationships the norm of the world.

Sabbath

A sub-group of the Monster Lord's faction, led by the Baphomet mamono. This group is comprised entirely of loli mamono and is dedicated to spreading lolidom over the world. Or, in other words, they want to convert all women into loli mamono, convert all non-loli mamono into loli form, and convert all human men into "Big Brothers" (lolicons). Technically allied to the Monster Lord, but with definite plans to usurp her if she doesn't agree with their goals after conquering the world.

Zipangu

The not!Japan of the setting, technically loyal to the Monster Lord and the shining example of what she wants to achieve, with humans and monstergirls living together relatively peaceful. Kind of Mary Sue, but what do you expect when the creator is Japanese?

Pandemonium

A faction operating out of a timeless demiplane. Allied to some power called "the Fallen God", they're basically extremists on the Monster Lord's plan who seek to reduce all existence to one eternal, never-ending orgy. KC only made two profiles for this faction - the Dark Angel and the Dark Priest - but hasn't touched it for ages. Maybe because they tended to be the biggest fuel for the "anti-mamono interpretation" of the setting in the early days.

The Gods

The creators of the world. Currently torn between those who support the Monster Lord's plan and those who support the Chief God, who wants to slay the Monster Lord and return things to the original cycle. Mentioned goddesses in the first faction include Poseidon, Eros and Ares.

The Order

The chief religion of the setting and basically your standard Weeaboo take on semi-Christianity. Dedicated to the Chief God first and foremost, their duty is to train Heroes to fight monsters. It's kind of unclear if they don't know that the new Monster Lord wants to end the cycle, or if they do know and are deliberately lying to general people so they still believe that all mamono want to kill and eat them. A lot of fans like to portray them as essentially a fantasy take on The Imperium.

Grimdarkness

Think this sounds like a happy-fun setting? Yeah, it looks that way, on the surface. But it ain't. Under the surface, it's pretty damn fucking grimdark.

The original Chief God created humans, but got worried about their numbers. So he created monsters to slaughter humans in sufficient numbers to cull them. Then he created the program of the Heroes and the Monster Lord; the Heroes get empowered when humans are too weak to disrupt the monsters' attack by killing their demigod leader, the Monster Lord, and then eventually a new Monster Lord rises up and starts the same shit over again.

He also forced the other gods to get in on this - Poseidon supports the new Monster Lord because she's sick of having to kill people with tidal waves, storms and sea monster attacks.

Think the new Monster Lord is any better? Only if you don't mind the fact that she's bungling her job, and so mamono have swapped "kill and eat humans" for "kidnap and rape" humans. Or the fact her stated goal is to drive human women extinct so human men have to marry monstergirls, and so she is actively seeking to convert (physically and mentally transform) all women into mamono.

To say nothing of the fact that, because the Monster Lord and new Chief God are fighting, a side-effect is that mamono can only birth more mamono, rather than mamono and human sons. So, potentially, the Monster Lord could cause a fucking extinction event if she doesn't sort something out before there are no human women left. And she's not slowing down on the "convert all human women into mamono" front anytime soon, by the way.

Creepy Shit

• There are lolis everywhere. No, seriously. Some of these girls are depicted as being so young it's fucking creepy.
  • Dwarves in particular look practically toddler-like. What's worse, the dwarf men apparently found their new women so hot that they eagerly supported the conversion, and now they're all extinct. There's only loli-dwarf women left.
  • Alices are "eternal virgins". After you fuck one, she regenerates her hymen and completely forgets what happened. KC tried to retcon this by revealing that they remember it subconsciously and eventually wander off to "Wonderland" where they get over this part, but seriously. Oh, and they also mind rape you so that even if you wouldn't initially tap that ass, eventually, you will. Fucking hell.
  • The Sabbath thinks lolis are superior, and wants to conquer the world. Up to and including forcibly converting all other mamono into lolified mamono.
• Mamono daughters start craving sex at about preschool age. And they'll happily fuck their dads if they can't get anyone else. And most mamono moms will not only let them, they'll fucking help them.
• The Sabbath runs the official mamono preschools. And they both happily let the girls fuck anyone who comes to visit and use them to recruit new members.
• If you're gay, the Monster Lord doesn't want you - getting exposed to "mamono mana" will transform you into a lusty flat-chested succubus variant called an Alp.
• When you boil it down, the Monster Lord basically wants to mindrape and physically convert every living soul on the fucking planet.
• The Monster Lord has that many advantages on her side it's basically in the bag that she's going to win.
• "Mamono mana" terraforms the world around monsters into the Monster Lord's vision of heaven. So even if you don't want to get involved, just letting monstergirls fuck their husbandos nearby will eventually poison the land you live on, causing more mamono to literally pop out of nowhere - your freaking pets and livestock may spontaneously transform into beastman-type mamono, and that's just for starters - and slowly mindrape you into supporting the Monster Lord.
