Alps are a unique variant of succubus born when a trans woman is monsterized by demonic energy—rather than turning them into incubi, in accordance with their sex, it resonates with their inner desires and turns their bodies female.

Devil Bugs are monster girls with the arms, legs, wings, and antennae of a cockroach. They are sentient, but rarely use higher reasoning, instead blindly seeking sex.

They never show their true form—a petite woman draped in black except on the New Moon, when they lose the ability to transform.

Ghosts are monster girls born from disembodied human souls infused with demonic energy. They are lustful by nature, but lack a physical body with which to copulate.

When a Dryad and her mate are having sex within, the tree produces a sticky sap that attracts other monster girls.

Dwarves are a race of diminutive monster girls with an inborn talent for fine craftmanship. They were originally normal humanoids, but due to monsterization practically all dwarven women are succubi, and almost no dwarf males exist.

They have been on good relations with humans since ancient times, and frequently trade in ores and handicrafts.

Elves are a proud, reserved humanoid race with pointed ears and delicate, natural beauty. They see themselves as superior to humans and other races, and live in isolated forest villages. They value their moral purity above all else, and disdain sex for the purposes of pleasure. For this reason, female elves are a favorite target of succubi, and the number of pure elves is decreasing as the population of succubus elves is increasing. They exile any elf tainted with demonic energy to keep the monsterization from spreading.

A succubus-elf is an elf who has succumbed to lust and demonic influence, and become a succubus. Due to her original purity, a she-elf does not initially grow horns, wings, or a tail when she becomes a succubus. She simply becomes unable to control her sexual urges, and uncharacteristically shameless in her seduction of attractive humans. The longer she resists her urges, the more powerful a succubus she becomes. Then, in contrast to her earlier austerity, she becomes remarkably perverted, reveling in the "filth" and decadence of sex.

Fairies are a playful, carefree race of miniature flying humanoids. They are typically no larger than a human hand, with iridescent, butterfly-like wings. They are not monsters by nature, but due to their naiveté, they are easily turned into nymphomaniac mamono by lewd pixies or imps. Alone, they are easy to rebuff—but when they attack in a swarm, it is easy to fall victim to a "vortex of sex" where you are being pleasured from every angle. They live in the Fairy Kingdom, a magical realm inaccessible to humans, unless guided or abducted by fairies.

Flow kelp are aquatic plant-type monster girls with long, dark, wavy kelp for hair, and kelp appendages instead of arms. They are quiet, gloomy creatures who grow on the ocean floor, but if they encounter a human they will tackle and tangle them up in the kelp draping their bodies, then have sticky, slimy sex. They prefer to cling to their human mates at all times. As they absorb fluids, their bodies tend to swell up, gaining a more voluptuous figure as their vaginas become more slimy and moist. They can also start to dry up if left unattended on land for too long.

Gazers are monster girls with who have a single, sinister red eye on their faces and many black tentacles with eyes at their tips. They are mean and arrogant by nature.

Their skin is pale, with splotches of smooth black skin over their arms and legs.

Genies are mischievous spirit-type monster girls with olive skin and pale hair. Genies live inside magical golden lamps, and when a human rubs the lamp, they emerge in a burst of purple smoke to serve their "master". They have godlike wish-granting powers, but they must first collect enough mana to grant each wish. A genie gathers mana through sex, so the greater the wish, the more sex she must have with her master to grant it. Even then, genies often twist their master's wishes to have unforeseen erotic consequences. If she has a mate, a genie can be free of her lamp for good.

Ghouls are undead monster girls with dark skin, light hair, and red body paint on their arms and legs. They are lustful, ferocious creatures that pounce on humans and lick them all over. Ghouls love to give fellatio and cunnilingus, and drink human cum. Their saliva makes a human's body more sensitive, so that even an affectionate nibble can cause spasms of pleasure. They rarely use their vagina for sex, and for that reason it is much more sensitive than the pussies of other monsters. They often pass out with pleasure when they have vaginal sex for the first time.

Houri are petite, angel-type monster girls with pink wings and hair. They are kind, gentle, loving beings who emanate an aura of purity and innocence.

They view sex as a sacred act of mutual love, and always enjoy having passionate sex with their chosen humans.

Giant ants are a species of monster girl with the torso of a human woman and the abdomen and antennae of an ant. They are diligent workers who live in large colonies centered around a queen. They have superhuman strength, and their pheromones attract human males. Giant ant workers who have sex with humans often gain the ability to reproduce, and leave the colony to form their own colony elsewhere as queen, along with their chosen mate.

Giant slugs are gentle monster girls with the antennae and lower body of a slug. They immediately make a beeline for any attractive human they see—however, they move very slowly along the ground. If a slug girl does catch up to a potential mate, they will be trapped by the slimy, sticky mucus covering her body, and be forced to have sex with her. Slug girls prefer to take their time having slow, moist, sensual sex, sometimes for hours at a time. Exposure to salt causes their bodies to temporarily shrink, but it does not kill or harm them.

Girtablilu are scorpion-like monster girls with light or dark brown skin and the lower body of a scorpion. They obtain mates by sneaking up on humans like assassins, then using their stinger to inject them with a venom that causes paralysis and arousal. They like to be dominant, often paralyzing their human mates with venom before sex. A human male's penis may become larger and harder as he is injected with more and more venom.

Dark gnomes are gnomes who have been consumed by sexual lust and demonic energy. The sprouts and vines on their voluptuous, earthy bodies have turned dark, and black markings like tattoos have appeared on their skin. They are ravenously lustful, and have sex with their covenanter (or mate) almost continuously, as if the two are rooted to one another. As a result of her corruption, a dark gnome's land will turn dark, and produce sinister-looking fruits of the demon realm. The demon fruits are nutritious, but have arousing aphrodisiac effects which further spread their perversion.

Glacies are frigid, spirit-type monster girls with sleek bodies made of crystalline ice. They are cold, unfeeling servants of the ice queens, and typically do not have any interest in sex. However, if a glacies is in close physical contact with a human for a long period, her frozen heart may thaw, allowing her to feel love and lust for the one who warmed her. A glacies can then feel joy from the love and warmth she receives from her mate. Her body will then start to thaw as well, until it feels soft and warm like human skin.

Gremlins are short, cunning imp monster girls with the ears of a beast. They are naturally skilled with machinery, and wield various lost technologies such as jetpacks, mecha arms, ray guns, and drones. They also develop sexual tech to please their human mates, including aphrodisiacs and stamina boosters. They can also sabotage various machines, and cause mechanical monster girls like golems and automatons to malfunction—turning them into sex fiends.

Grizzlies are monster girls with brown hair and fur, and bear paws and ears. They are ordinarily gentle and docile creatures, but turn ferocious and aggressive when aroused. Their favorite food is alraune honey, which they always harvest with their right paw. Sniffing this paw will cause them to become aroused and go feral, often destroying human settlements with their powerful limbs. They love to give their human lovers bear hugs.

A covenant is a magical, binding agreement made between an elemental monster girl and her human mate, or covenanter. Tantamount to marriage, it typically states that the human will continue live with the elemental and provide her with mana (through sex), in exchange for a portion of the elemental's magical powers. The covenant is typically formed the first time an elemental and her human mate have sex, but it cannot be made without the consent of both parties.

Gnomes are earth elemental monster girls with bodies made of soft, fertile soil and budding sprouts growing from their head. They are gentle, benevolent nature spirits who tend to the land they were borne of. They approach humans they like by embracing them with their voluptuous female body, tempting the humans with sex and a covenant. Gnomes enjoy cuddling and slow, sensual lovemaking. A gnome's health is linked to the land she oversees—the more sex a gnome has, the more beautiful and bountiful her land becomes. They can create multiple bodies out of the earth.

Goblins are short, demihuman-type monster girls with pointed ears and small horns. They are cunning and mischievous by nature.

They tend to be quite possessive, and help themselves to any human they want as their mate.

Greenworms are monster girls with the antennae and long, segmented lower body of a caterpillar. They are voracious plant eaters with soft, squishy bodies. Their antennae secrete a liquid with an alluring, weakening scent. When they've eaten enough to metamorphose, they seek a mate who will keep them company inside the chrysalis. They have sex with their mate inside the chrysalis, feeding on each other's bodily fluids, until the greenworm emerges from the chrysalis as a papillon.

Gyoubu danuki are cunning, ambitious monster girls with the fluffy brown ears, legs, and tail of a tanuki and yellow eyes. They are typically successful merchants by trade. They can use magic to perfectly disguise themselves as human. They infiltrate human society, using their impressive business acumen to buy out competition and reach positions of power. They use debt to force humans into submission, then have sex with them. Though underhanded, they are compassionate at heart—they hoard power in order to create a prosperous and peaceful human-monster society.

Golems are monster girls made of clay, animated by magic. They have arms and legs of brick or stone, but a torso which is soft and smooth like skin. They are programmed to extract spirit energy from humans through orgasm, then bring that spirit energy back to their mage-creator, but their programming can be overwritten by erasing or changing the runes inscribed on their arm. If a golem falls in love with a human, that golem will gain emotion and a will of her own, and follow only her heart.

Griffons are fierce, proud monster girls with magnificent eagle wings, taloned hands, and the tail, paws, and fur of a lion on their otherwise humanlike lower half. They are zealous guardians of legendary treasure, attacking and having sex with any human who comes close. As a treasure hunter has wild sex with a griffon, their desire for treasure will slowly subside, replaced with desire for the griffon. Griffons are flattered by that desire, and respond with passion and devotion.

Hakutaku are calm, wise monster girls with the horns of a cow, a long, bushy white tail, furry legs, and hooves. They are dedicated scholars who have wide knowledge on a variety of subjects, particularly other monster girls—they can teach a human to seduce and pleasure any kind of monster girl. They can transmit or receive knowledge through touch. As a result, they become gradually more physically intimate with their human students, leading to hands-on sex lessons and sometimes marriage. Through touch, they both learn their mate's sexual preferences, and teach their mate their own.

Hellhounds are monster girls with black skin, red eyes, and the black paws, ears, and tail of a hellish dog. They are ferocious creatures who hunt down and have sex with any human they find. They prefer wild, violent sex, and will fuck their human mate as roughly as they can without harming them. They are considered totally untameable; though they sometimes consent to submissive play, they always return to being the dominant partner. A hellhound loves her mate with a burning passion, and will attack all who threaten her mate with unmatched ferocity.

Harpies are cheerful monster girls with wings for arms and taloned bird feet. For most of the year, they are friendly and helpful creatures who get along well with humans.

Once mating season is over, they are warm and loving towards their human mate, with no sign of their initial agression.

High orcs are monster girls with the ears and tail of a boar, and furry arms and legs. They have brown skin, and wear boar skulls like crowns. They are strong, quick-witted warriors who lead packs of lesser orcs into battle. High orcs have a pungent musk which arouses both orcs and humans. They love to capture and dominate humans in sex. However, when defeated in battle they become submissive to their human master, and use their voluptuous bodies to pleasure them. Their powerful scent becomes like an addictive aphrodisiac to their human mates.

Hinezumi are hotheaded, pugnacious monster girls with the ears and tail of a mouse, and flaming arms and legs. They are skilled martial artists who are only aroused by humans who beat them in a fight. Their flames burn only pleasantly warm to the touch. Ordinarily a hinezumi's flames ignite fighting spirit—but if she is aroused, the heat of her flames incites lust and arousal instead. If a hinezumi's flames are doused by water or cum, she becomes temporarily timid and submissive. A hinezumi can briefly share her coat of flames with her mate.

Holstaurs are gentle, docile monster girls with the horns, tail, and furry legs of a cow. They continuously produce delicious, nourishing milk from their massive breasts. They are simple, slow-witted creatures who express affection and arousal towards humans by rubbing their huge breasts up against them. Ordinarily they are perfectly harmless; but if they see the color red, they go feral like minotaurs and have rough sex with the first human they see (or, if they're married, rush back to their human spouse for sex).

Honey bees are monster girls with the abdomen, antennae, and translucent wings of a bee. They live in a hive centered around a queen. Most bee girls are workers, whose duties include gathering pollen and alraune nectar for the hive, as well as finding potential mates for the queen. They test potential mates by having sex with any humans they meet, then bringing them back to the hive. They are gentle and dedicated by nature.

Kamaitachi are monster girls with the ears and tail of a weasel. They can use the scythes on their forearms to create blades of wind. They always appear as a trio: a buxom one, a svelte one, and a petite one. When the trio see a human, the svelte one knocks them down, the buxom one cuts off their clothes, and the petite one rubs medicine in their wounds. The petite one's gentle winds calm the human, and the medicine contains an aphrodisiac that causes the human to find them attractive. They then have sex with the human in a perfectly-coordinated foursome.

Kappas are friendly aquatic monster girls with green skin, webbed hands and feet, a small turtle shell on their backs, and a dish-shaped object on their heads. They are mischievous creatures who like to sumo wrestle—playfully at first, but then as a way to push over and pin their desired mate. Kappa tend to choose their childhood friends and wrestling partners as their mates. They are most powerful when their bodies are dripping wet. Kappa seem to wear sexy form-fitting swimsuits, which are in fact a thin, removable layer of scales. They love to fondle and eat cucumbers.

Hornets are monster girls with the abdomen, antennae, and wings of a wasp. They are similar in appearance to bee girls, but of a mean-spirited and voracious nature. Their stingers contain a paralytic and aphrodisiac venom, which they use to immobilize humans before having rough sex with them. If the queen does not need a mate, they will keep any human they find for themselves, to dominate whenever they please. They are the natural enemies of the honey bee, and attack any they find on sight.

Ice queens are elemental monster girls with shapely bodies of fine white snow, who wear regal dresses of dark frost and a crown of brilliant ice. They are powerful magic beings whose presence cools the weather of the frigid regions they rule over. Their magic freezes even their own hearts, making them cold, unfeeling rulers. Chilling winds constantly blow from their bodies, freezing the hearts of any who come close. But if a human should kiss her, an ice queen's heart may thaw, and fill with love for her human consort. She will then hate to be apart from her spouse's warmth.

Ignis are fire elemental monster girls with erotic bodies wreathed in intense flames. They are lustful, carefree creatures who are always seeking humans to have sex and form a covenant with. The flames on their bodies are only pleasantly warm to the touch, but will cause sudden, intense arousal in a human the ignis is interested in. They then have wild, passionate sex, binding the covenant. Ignis often have crude, impulsive personalities, but their love for their covenanters is earnest and strong.

Dark ignis are ignis that have been transformed by desire and demonic energy, as a result of having too much sex with their covenanter. Their ordinarily bright, fiery bodies are covered in black markings and dark, armor-like skin on their arms and legs. They are relentlessly lustful creatures who ravish their covenanter at every possible opportunity. Not only do their flames turn into arousing, corrupting hellfire, but all the flames in their vicinity become hellfire as well, spreading their uncontrollable lust and causing orgies for miles around.

Inari are reserved, dignified monster girls with the ears and tails of a fox. They prefer to find mates through polite courtship and seduction. They conquer sexual partners through skillful sexual service and technique. They tend to be more devoted and monogamous towards their human mates.

Imps are short monster girls with demon horns and tail, and small bat wings attached to their waist. They are simple-minded creatures who are blunt about their feelings and desires.

It is possible for a mage to bind an imp as their familiar through a contract, but the mage must take care that their roles are not reversed.

Ittan-momen are enigmatic monster girls who are sentient pieces of living cloth animated by demon energy. They have complete control over the shape of their bodies, and bend and fold themselves to mimic the appearance of a human woman. They are made of soft, cotton-like fabric, but they can simulate the sensations of a woman's body as well, from the feel of breasts and skin to the warmth and wetness of a vagina. They love to wrap themselves around their human lovers to pleasure them, then absorb the cum into their fabric bodies.

Jabberwocks are dragon girls with dark purple scales and light brown skin. The Queen of Hearts transformed them into lascivious dominatrices.

Kesaran pasaran are bright, cheerful plant-type monster girls with bodies covered in what looks like balls of fluff. They have small, light bodies, and they typically drift from place to place on the wind. The fluff on their bodies is actually a hallucinogen which causes a pleasant, intoxicating high when inhaled. Humans who breathe it in will mindlessly seek pleasure and happiness, likely having sex with the kesaran pasaran. The more mature a kesaran pasaran is, the stronger the euphoric, hallucinogenic effects of her fluff are.

Jiangshi are undead monster girls with pale bluish-grey skin and sharp violet nails who wear a Chinese hat and robes. Their bodies are immaculate and unmarred by death, but their movements are stiff and abrupt, and they often move around by hopping. They have superhuman strength and high intelligence. Having sex warms and loosens up their bodies, allowing them to move more freely. Attached to their hat is a paper talisman which gathers demonic energy. Changing the characters on the talisman can slightly change a Jiangshi's powers and disposition, but not without her consent.

Jinko are calm, reserved monster girls with the ears, tail, and striped fur of a tiger on their arms and legs. Jinko are ordinarily dauntless, disciplined fighters who show little to no interest in sex. But during breeding season, they become horny and flushed, and throw themselves at the first human they can get their paws on. They then have wild, relentless sex with that human, continuously, until their powerful urges are sated. Junko will revert to their stoic selves after breeding season, but they can go into heat anytime if they sense that their mate is horny.

Jinns of the jar are mimic-type monster girls with a large jar around their waist, olive skin, and pale hair. Like mimics, they pose as ordinary jars, then suck approaching humans into their personal dimension to have sex with them. Being timid creatures, they unconsciously use charm spells to force the human to make the first move on them. There is no escape from the jar except by the jinn's own power. Breaking a jinn's pot before she sucks you in will strip her of her powers, but it also makes her inconsolably sad.

Jorou-gumo are monster girls with a yellow-and-black striped spider lower half. During the day they are gentle and friendly, seducing humans with kindness, but by night they are fierce and sadistic, binding humans and having sex with them for hours on end. If their partner is submissive, they will become more dominant and sadistic—but if their partner dominates them during the day time, their sadistic tendencies will start to recede and vanish.

Jubjubs are harpy monster girls with large, plump breasts and floofy pink feathers and hair. They are just as friendly as ordinary harpies, but much more lustful.

Kitsune-bi are spirit-type monster girls with fox ears and tails, and bodies composed of spectral flame. They are spontaneously produced from the demonic energy of youko and inari. At first they are only entities of lust with little consciousness of their own, but through having sex with humans they gain a sense of identity and the capacity for more complex thoughts and desires. In the process, their flickering bodies become more solid as well. They can also possess human women, turning them into kitsune-tsuki.

Kakuen are monkey-like monster girls with prehensile tails, and fur on their forearms and lower legs. They are cheerful, arrogant, selfish, and cunning.

Karakasa-obake are monster girls who are umbrellas that came to life. They have a humanlike body with a giant umbrella hat that has a single large eye, and along, wide tongue. They use this to ensnare potential mates, and prepare them for sex. They have a fetish for being used, and are always seeking an "owner". Their personality depends on how they were treated in their past life. By closing their umbrella around their owner, they can create an isolated pocket dimension for just the two of them to share. Karakasa-obake get horny on rainy days.

Living armor is a ghost-type monster girl which possesses a suit of armor. Ordinarily only their armored exterior can be seen, but their chosen human can see their true form, a translucent, spectral woman within the armor.

Armor girls are shy and inept at expressing their feelings, though they are very devoted to protecting their wearers.

Kitsune-tsuki are ordinary human women possessed by one of the fox spirits, or kitsune-bi, produced by youko and inari. They keep their memories, consciousness, and appearance from being human.

In rare cases, kitsune-tsuki who have had copious amounts of sex may transform into youko or inari, depending on their personality.

Khepri are monster girls with olive-to-dark skin and a scarab's golden chitin on their arms, legs, and wing covers. They live in desert ruins in large groups, and when a human arrives, the khepri will take them to the "king's bedroom," and treat them to excellent hospitality while having sex with them one after another and feeding them balls of demon energy. Eventually the human will become an incubus or succubus, and rule over the selfless, devoted khepri and their ruins as pharaoh.

Kikimora are monster girls with the ears and tail of a dog, feathers on their wrists and tail, and feet like scaly boots. They are gentle, devoted maids who are skilled in every kind of housework, and devote their entire being to a single master. They are so sensitive to human emotion they can sense their master's needs and wants with only a glance. They happily attend to their master's sexual needs as well, though they never seek sexual gratification for their own sake. The only thing they won't tolerate is laziness—they always encourage their master to be productive using sex.

Kobolds are docile, friendly monster girls with the fluffy ears, paws, tail, and fur of a dog. They are completely harmless creatures who are loyal to a human master. Intelligent but single-minded, they express their emotions in simple, straightforward ways. When they want affection, they snuggle up against their master; when they're happy, they wag their tail. They get aroused from being petted, or simply smelling their master's scent. A kobold's master will gradually become accustomed to touching her in lewd ways, and even having sex with her.

Krakens are large, aquatic abyssal monster girls with ten squid tentacles in place of legs, and a squid's crown on top of their heads. They are powerful, amorous creatures who will drag entire ships into the sea to be with a human they love. The kraken then spits out black energy to darken the sea, so that the only thing the human can see is her glowing white body, and they have no choice but to swim into her loving embrace. They are calm and carefree by nature, but like Scylla they keep their mates wrapped up in tentacles as they have sticky, slimy sex at the bottom of the sea.

Large mice are small monster girls with the ears, tail, and forelimbs of a rat. They are restless, hasty creatures who are always skittering about in dark places looking for their next mate or meal.

After changing her target's heart, a kunoichi stays by their side as wife and bodyguard. A kunoichi only reveals her face and personality to a mate she truly trusts.

Lamias are monster girls with the upper body of a human woman and the lower body of a snake. Their vagina is located at the juncture between their human and snake halves.

They become extremely horny just after their lower halves molt, about once per month.

Lava golems are ferocious, passionate monster girls made of living lava. The molten rock of their bodies is softer and warmer than human skin. They can harden or soften their bodies at will, but most of the time their hands, breasts, ass, and genitals glow orange with hot lava. The lava on their bodies only causes mild, arousing warmth. They are fierce and relentless during sex, and it is said they cause orgasms as intense as volcano eruptions.

Lesser succubi are monster girls in a transitional state between human and succubi. They have smaller horns than full succubi, translucent pink wings and horns and soft downy fur on parts of their bodies.

They show their mate a sensitive side of themselves they dare not show in public, and are submissive and devoted towards the one who defeated them.

Matango are fungus-type monster girls with a large mushroom cap on their heads and smaller mushrooms growing elsewhere. They are largely idle and unintelligent creatures. They grow with their feet rooted to trees or the forest floor, so they cannot walk or move around. They constantly spread parasitic spores which travel on the wind and infect passing humans. If a human male ingests the spores, he grows a giant mushroom on his head which controls his thoughts, leading him to seek out and have sex with the matango. A human female who ingests the spores will gradually turn into a matango.

Mad Hatters are monster girls who wear a colorful, dapper suit and a large top hat which is actually a mushroom grown from their bodies. They are keen, intelligent creatures who like to charm humans through suave, eloquent speech over a cup of tea. They persuade humans to have sex with them in polite, logical fashion, while the spores they emit make humans more receptive to their lewd way of thinking. They can remove their mushroom top hat as if it were an ordinarily hat, and if a human female puts that hat on, she will rapidly transform into a Mad Hatter.

Mandragora are timid, plant-like monster girls with roots growing from their bodies and a large, fragrant flower on top of their heads. They ordinarily dwell in the soil, with only their head-flower visible above ground. The sweet scent of their flower will attract humans to come uproot them. When uprooted, they let out a magical scream that causes any creatures in the vicinity to go feral, and act on pure sexual instinct. Once removed from the soil, a mandragora's body ceases to grow—the longer she has been in the soil, the more mature her body appears.

Medusa are prideful monster girls with the lower body of a snake and snakes growing out of their hair. Their gaze can turn humans to stone, but the petrification is harmless. They primarily use it to immobilize potential mates and drag them back to their lair.

Though they are stubborn creatures who hate expressing their feelings, the body language of the snakes on their head will always show their true feelings.

Mermaids are aquatic monster girls with the upper body of a human woman and the lower body of a fish. They are gentle, innocent creatures who spend much of their lives in romantic daydreams about their future human lover.

They will still try to be look stoic in public, but in private they are warm and loving towards their human mates.

Nureonago are slime monster girls with bodies formed out of white, translucent goo. Even among slimes they are excellent shapeshifters, able to mimic the shape of clothes, like kimono, and change color to simulate hair or skin. They still appear to be soaked, however, so they tend to seek mates during rainstorms, when they can convincingly pretend to be human. Once they've decided on a mate, they will pursue them to the ends of the earth. They are gentle, demure creatures who are very devoted to their mates. Although not very intelligent, they are naturally skilled housewives.

March hares are cheery, lustful monster girls with red bunny ears, and fluffy pink legs and tail.

After the initial encounter they are gentle and protective towards their mates, as they are really kind, nervous creatures who need physical intimacy with the one they love.

Mimics are monster girls who can perfectly disguise themselves as treasure chests. They are mostly human in appearance with a chest affixed around their waist. They wait in dungeons for adventurers to arrive, then spook them by popping out like a mostly-naked jack-in-the-box. They then cast a binding spell on the adventurer and have sex with them. If they like an adventurer, they may grab them and pull them into the treasure chest, never to return—it is thought that within the treasure chest is a pocket dimension where they have sex with their mates without end.

Slimes are semiliquid monster girls with bodies made of blue, translucent goo. They can form their bodies into almost any shape, but most often take the shape of a sexy woman to better attract mates.

Will-o-the-wisps are undead monster girls born from the regrets of those who died alone. Their bodies are made of flames of burning jealousy, which burn the soul instead of the body. They wear a cage to contain their flames, so they often look like lanterns or chandeliers. They burn brighter with rage when they see couples in love. They trap their human mates inside their flame-cage, where they have relentless sex even after their mate's death. They are lonely and gloomy by nature.

Wonderworms are monster girls with a humanoid upper body and the long, segmented lower body of a caterpillar. They are languid, laid-back creatures who spend most of their time reclining on a toadstool, blowing smoke from a hookah pipe. A wonderworm's smoke and breath is intoxicating to humans, lulling them into a dreamlike, aroused state. She will typically give her desired mate a whiff of her smoke, then embrace them with her squishy, voluptuous body. They like to kiss or fellate their partner when not smoking their pipe. They have blue and white skin and hair.

Wyverns are lesser dragon-type monster girls with wings on their arms rather than than their back. They are weaker than full dragons, but are more gifted fliers. They have abrasive and impulsive personalities, often swooping down to abduct potential mates. Many work as mounts for dragoon knights, who ride them through the air into battle. They are difficult to tame, however, as they prefer to be on top in sex and in battle. Love and trust are essential to riding them.

Zombies are undead monster girls who are female human corpses reanimated by demonic energy. They retain their memories from being human, but have fairly low intelligence. Their bodies remain preserved and pristine as long as they have demonic energy, but they require a human's sexual fluids to maintain their body. They shamble about graveyards and crypts at night seeking a mate. As a zombie has more sex, her appearance will become more human, and her intelligence can be restored.

Yeti are monster girls with light brown skin and fluffy white hair and fur over their large hands and feet. Yeti are kind-hearted, gentle creatures who often save freezing travelers by hugging them and sharing their body heat. They love to hug and cuddle with humans, but also enjoy having tender sex if the cuddling happens to arouse their partner. Yeti have high body heat which rises even further when aroused.

Yuki-onna are gentle, dignified monster girls with cold bluish-white skin that wear tasteful blue and white yukatas. They have the magical ability to create snowstorms, which they use to guide wandering humans toward their home. They then give the human great hospitality, before offering sex. If the human refuses, the yuki-onna can use her frost breath to chill their heart, making them desperate to lie with her. The insides of their bodies are surprisingly warm, and sex with them is hot and passionate. Yuki-onna rarely let their mates leave once they have them.

The Cataclysm was the devastating event that ended human civilization. Portals opened all across the world, spawning hordes of monster girls that hungered for human seed. The unstoppable hordes laid waste to society, spiriting away men to their accursed realm as women were transformed into more monster girls. Those humans who survived fled into the wilds, hiding in shelters and abandoned barns as the cities were overrun by the mamono. The cities now act as the headquarters of the Demon Lord's forces, regularly sending groups of monster girls to hunt for the men still left behind.
