A Plant from the Tentacle Forest

A tentacle forest is a vast, wriggling ecosystem of semi-sentient tentacle plants. Inevitably, their primary function is tentacle rape, of human and monster girls. The tentacle plants themselves are technically just flora, not monsters, and so they were not transformed into monster girls by the Demon Lord's sorcery. However, like other creatures and objects in the Monster Girl Encyclopedia world, prolonged exposure to concentrated demonic energy can cause them to transform into a monster girl in their own right: the Tentacle.

Tentacle plants that absorb enough energy may become a Tentacle monster girl

It is not clear whether there are multiple tentacle forests or just a single one; certainly the vast majority of information relates to a single, large forest on the outskirts of Royal Makai. Although the regular tentacle plants have no demonic energy themselves, they are able to feed on it in a similar manner to monster girls feeding on spirit energy; and they have a similar tactic of raping it out of the creatures that possess it, which in this case is monster girls themselves. The tentacle plants have, however, learned from experience that they can get much more sustenance by mooching off the magical perpetual-motion-machine that is succubus/incubus sex; and so if a monster girl and her husband wander into the forest, the tentacles enthusiastically assist them in getting off together. This feature has led to the outskirts of the tentacle forest becoming a favorite getaway for the residents of the Royal Demon Realm. In the case of a human woman unfortunate enough to wander into the area, the tentacles just violate her until she becomes a monster - usually a roper or regular succubus - then dump her on the edge of the forest.

The deeper reaches of the Tentacle Forest hold a great prize for monster girls: the Treasured Child Tree, an agglomeration of tentacles whose sap functions as probably the most potent and foolproof fertility enhancer in the world, guaranteeing conception if ingested. Since monster girls' second deepest desire (after sex with their husband) is the hope that that sex leads to a child with their beloved, a quest to the center of the tentacle forest to get at that sap is one which plenty of couples have embarked on. Even for exceptionally powerful monster girls, though, it's not easy; the tentacle plants deeper in the forest are very, very good at raping couples into submission and turfing them out.

In the Demon Realm Traveller's Guide there is a whole chapter detailing the various subspecies of tentacle, and the forest's history. In the eras of former Demon Lords, and even into the early part of the current Demon Lord's reign, the tentacles were vicious killers that would dismember men and forcibly impregnate women - human and monster both - to become mindbroken wombs for the tentacles' offspring. The Demon Lord and her husband personally and brutally culled the Tentacle Forest to a tenth of its former extent to stop this behavior, impressing upon the plants in no uncertain terms that they'd better start acting as sex aides instead of murderers if they wanted to survive in her new world order.

Book Information

Forest of Tentacles (Early settings info)

An evil forest of ominous, moving plants that exists in the demon realm. When they spot a female, regardless of her race, the vine shaped plants that live in this forest will coil around her body, bind her in place, tease her, and penetrate every single orifice in order to suck out magical energy. In the outskirts of the forest, the plants are comparatively docile. It is said that human and monster couples and married pairs also come to play with the goal of using the tentacles during sex. But when a human woman who lacks the proper resistance enters the forest, the plants just keep totally violating her. She'll probably end up becoming a succubus or roper with nothing but thoughts of pleasure in her head and going back. Also the deeper into the forest one goes, the more ferocious the plants become. It's supposed to be so extreme in the deepest part that even a monster would hesitate to go there.

The Forest of Tentacles (MGE-1)

A devilish forest crawling with ominous vine-shaped “tentacle plants” that exists on the outskirts of the demon realm. When they spot a female, regardless of her race, the tentacle plants of this forest will coil around her body, bind her in place, tease her, and penetrate every single orifice in order to suck out demonic energy. Since the tentacles know that a monster's demonic energy improves in taste and quality after she obtains spirit energy, if a monster brings her husband to visit, they'll coil around her and shower her with sticky juice that includes an aphrodisiac compound that makes monsters terribly aroused, then coil around her thighs and force her legs wide open, and face her in the man's direction, as if inviting him to hurry up and penetrate. Since the plants in the outskirts of the forest are comparatively docile, and disposed towards aiding them by making sex with their husband more exciting, many monsters bring their husbands with them when they visit to play. They enjoy the pleasure that using tentacles during sex with their husbands brings. But when a human woman who lacks the proper resistance enters the forest, the plants just keep totally violating her. She'll probably end up being transformed into a succubus or roper with nothing but thoughts of pleasure in her head by the time she emerges. Also the deeper into the forest one goes, the more ferocious the tentacles become. It is so extreme in the deepest parts that even a monster would hesitate to go there.

Tentacle Forest (World Guide II)

Known as a "tentacle plant", these are a common form of vegetation in demon realms.

Able to move under their own power, these plants are almost like animals and are actually intelligent, some tentacle plants even understanding human language. when a monster or a human women enters the Tentacle Forest they will be swarmed by tentacles, covered head to toe in these tentacles. They will have their mouths, wombs and even ass violated with pleasure and aphrodisiacs while the plant sups on their spirit energy. In the case that a human woman is attacked, all of her natural spiritual energies will be sucked up and monstrous demonic energy will flow into her changing her into a succubus.

These plants also know that if a monster is able to sample a male's spiritual energy they will create a larger amount of energy than normal. Because of this, when a monster approaches a tentacle plant alongside a human male, it will grasp her, twine it's tentacles around her limbs to restrain her, caress her body with the syrupy aphrodisiac mucus it produces and, while violating her to arouse her, flip her over and turn her so that her genitals face the human male. When the monster and human male begin to copulate the tentacle plant will continue to smear both participants with it's aphrodisiac mucus and, twining itself about both participants further, begins to force them together at it's own pace, the tentacles devoted to supporting their sexual intercourse. In this way the couple having intercourse will have very vigorous sex, release large amounts of mana for the plants to sup upon, allow the plants to also have sexual intercourse and, hopefully, convince the participants to become repeat visitors.

The tentacle plants at the outer edges of the Tentacle Forest are, comparatively, quite docile, and as such, are regularly used to assist during intercourse. Many lovers, parents and their children and friends regularly visit these areas for picnics. These docile tentacle plants being quite intelligent, so much so, that they even enjoy playing with children.

However, when one goes further and further into the Tentacle Forest, the tentacle plants become more violent and dangerous. The most extreme tentacle plants are completely brutal and merciless, while these plants won't kill their prey, they will completely violate them until they collapse from exhaustion and lose consciousness. Those violated by the tentacle plants to the extent that they have passed out are, by the tentacle plants themselves, passed back to the entrance of the Tentacle Forest.

The innermost portions of the Tentacle Forest are avoided, even by monsters, except in exceptional cases like those mentioned later. This innermost portion of the forest is something only the most devoted married couples challenge. However, even devoted couples are typically found at the entrance of the Tentacle Forest, dripping with aphrodisiac mucus, pussy juices and jizz, completely unconscious after failing the challenges of the depths of the Tentacle Forest.


"If you go on a trip to the Tentacle Forest, you will get covered in the tentacle plant's mucus, your dear's jizz, and a variety of other fluids that will ruin your clothes so please remember that before visiting."

Standard Tentacle Plant
Twining about people, stroking them and making them all sticky, this is the typical tentacle plant. Since there is nothing special to define this version of the tentacle plant, please refer to the introduction for their description.

Tentacle brain

Tentacle Brain
Somewhat small and short tentacles distinguished by having an eye-like organ. They only live towards the periphery of tentacle forests. Even among all the tentacles, their intelligence is extremely high, and they seem to even be able to understand human language. These tentacles supervise the other tentacles, and are sort of like the tentacles' brains. They also have the role of controlling, and commanding the other tentacles. When multiple tentacle plants work together to violate women, or force men and women to have sex, they're able to move in synchronization due to the functioning of these tentacles. Solely due to the fact that tentacle brains have evolved towards coexistence with monsters, they're friendly towards people, have a docile personality, and an adorable appearance, which makes them popular as pets.

Man Marionette
These are tentacles that live towards the deeper part of a tentacle forest, and unlike most other tentacles which focus mainly on women, these rare tentacles prioritize assaulting men first, and they're one of the biggest reasons that monsters can't make it to the deepest part of tentacle forests. First, a tentacle assaulting a man will release mucous inside the man's mouth, dulling the man's thinking. Then it will wrap itself around the man, as if to cover him up, and “infest” him. The consciousness of infested men grows hazy, and the consciousness of the infesting tentacle flows inside them, creating the hallucination that they have become one with the “tentacle”. Such men completely forget things such as the original reason why they visited the tentacle forest, and become only able to think about raping and violating the female in front of them.

When a man becomes a “tentacle” in this manner, all the tentacles around him will start to obey him as if he had become the king of the tentacles. The “tentacle brains” which serve as the brains of tentacles that were mentioned before only inhabit the periphery of tentacle forests and not the deepest parts. In other words, deep within these forests, it is the men who enter that serve the role as the brain of the tentacles.

Once this happens, it's all over because it will be the monster's husband doing the assaulting, and a monster's female body is exclusively made to receive the maximum amount of pleasure and mana from her husband. Even if vigorously rubbed and fondled all over her body, if she feels that it's pleasure from tentacles, she will be able to endure it indefinitely, but if it's her beloved husband then her body will surrender after just one squeeze of a breast, and her heart will surrender after a single kiss.

Then, after being forced to swallow semen mixed with aphrodisiac mucous and having it shot inside her womb by her tentacle-infested husband, she will change into a mere female beast that can think of nothing but copulating with her beloved husband. A man and woman who have had sex together as a couple in this manner with the aid of the tentacles until becoming all sticky and messy will be released after passing out, and forcibly sent back to the entrance of the tentacle forest.

Treasured Child Tree
Huge trees in the deepest part of a tentacle forest that tower to the extent that one must look up at them. Or rather, they look like trees, but in actuality, they're mostly aggregations of many tentacles that became like an enormous tree by becoming entwined together. Upon closer inspection, one can tell that the surface is wriggling. These are what the married couples aiming for the deepest part of the forest are truly after. The tentacles around these tentacles are mostly docile in spite of it being deep within the forest, and they just surround the couple from a distance as if to praise them for arriving in the deepest part, otherwise doing nothing.

When a couple arrives at the base of one of these huge trees, it will extend just one of its thick tentacles towards the wife's mouth. When the wife takes that tentacle inside her mouth, it will release mucous that's so sticky and hot that nothing released by other tentacles can compare to it. After ingesting this mucous, the wife's stomach, or rather, womb will grow hot. This is because her womb will enter an active state due to the mucous. If she has sex with her husband in this state and receives semen in her womb, she will definitely be able to conceive a child.

This is the reason why man and monster couples will keep challenging these forests no matter how many times they are forcibly sent back to the entrance. As far as monsters are concerned, conceiving a child, which is the crystallization of the love they share with their husband, is the greatest happiness as a female, and one of the most important meanings of life.

By nature, it is extremely difficult for monster human couples to have children compared with human couples. Some monsters have lifespans that last centuries, or even millennia, and if they're unlucky, they won't be able to have children even after years, decades, or even centuries of having sex a two-digit number of times every day. Because of this, when monsters are not blessed with children, they decide to challenge a tentacle forest again and again, seeking a crystallization of the love they share with their husband.

Fairy Hug

Fairy Hug
These are tentacles that live towards the periphery of tentacle forests, or sometimes even inside forests in the human world. As the name suggests, they're tentacles that feed on the mamono mana of fairies and specialize in attacking races such as “fairy” and “leanan sidhe”. Normally, they have an appearance like a flower bud with closed petals, and at a glance they don't look like tentacle plants, but the inside of the flower is tightly packed with tentacles. They give off a fragrant scent, like the sweet confectionery that fairies prefer, to lure them in; and once a fairy approaches, the flower will open and seize her by enveloping her entire body as though hugging her closely. After a tentacle flower has engulfed a fairy's entire body, it will then violate her with a swarm of tentacles while painting her entire body with mucous.

In the case that a fairy who has not been monsterized is attacked by these tentacles, her innocent body will be thoroughly instilled with pleasure, and imprinted with demonic energy, so she will change into a monster and seek to have sex with a human man. If taught about pleasure and changed into a monster in this manner, the fairy will definitely become a repeat visitor, and what's more, she'll also start bringing her friends to the tentacles to teach them about pleasure too.

Also, after these tentacles attack fairies, a large amount of the scales from the fairies' wings stick to the inside of the tentacles' petals. This is what is called “fairy powder”, and it's useful for things such as magic potions.

Fairy Powder

Main article: Fairy Powder

Fairy powder is made up of scales from the wings of fairies. The beautiful powder faintly glitters in 7 colors, and is filled with the magic of fairies. It is treasured for uses such as an ingredient for magic potions, or dye, when inscribing runes. Furthermore, it is said that one can travel to the Fairy Kingdom by sprinkling it over their head, but let's just say that that's more of a half-truth. It's not that one will be able to fly directly to the Fairy Kingdom. Instead, a man covered in this powder will become extremely popular with fairies, and a huge number of monsterized fairies will swarm over him eager to play sexual games, so eventually he may be taken to the Fairy Kingdom. It also affects more than just fairies, influencing races of monsters with a childish appearance such as imps, goblins, and even baphomets by causing them to take a liking to a man and go wild with lust more easily.

Also, after raping a fairy, these tentacle plants do on occasion open their petals and bloom in full glory while displaying the mucous-covered fairy that had gone limp due to pleasure in what almost appears as a crucifixion. On such occasions, they often encounter human men looking to collect and sell fairy powder. When a fairy whose mind has become obsessed with pleasurable games due to the tentacles' hardcore training notices the human man that has appeared in front of her, she'll spread her legs on her own without even needing to be forced by the tentacles, and invite the man in front of her to use her body. Among those whose profession is to collect and sell fairy powder, a plant in this state is referred to as “fruit bearing”. It is said that most of those who work in this profession will inevitably end up having several fairies as wives.

Tentacle Story

The tentacle plants of the age of the former Demon Lords were atrocious plants that would kill males, whether monster or human, and convert them into nutrients; and rape all females, impregnating them with their own seeds, using them as seedbeds.

However, when they gained intelligence with the ascension of the current Demon Lord, the tentacle plants ended up having to dramatically change their mode of life. For tentacle plants, the first turning point was when monster ecology changed. They came to have forms like that of human women, which made them easier for the tentacle plants to rape, at least ostensibly. Up until then, they had been able to change females, whether human or monster, in such a way that after having their entire bodies violated by the grotesque pleasure of the tentacles they would forget all about males of their own kind, and think only of bearing the tentacles' offspring. However, the monsters of the new era would never forget their husbands, and the inhuman pleasure induced by countless tentacles could no longer at all surpass the pleasure induced by a man's single meat rod.

Additionally, the bodies of monsters had changed to be specialized exclusively for their husbands, and would not accept the seeds of the tentacles at all, so the tentacles became unable to have monster females birth their offspring. The tentacles then considered targeting human females, but because demonic energy had even pervaded the tentacle forest, human females immersed in pleasure by the tentacles would soon change into monsters.

Realizing that it was futile, the tentacles decided to stop using living things as seedbeds, and instead they ended up trying to reproduce like ordinary plants by planting their seeds in the ground and sprouting them. However, a problem occurred here. Until then, they had sprouted their seeds using the rich nutrients of a mother's body, and just the nutrients in the soil were insufficient to sprout their seeds.

For that reason, the tentacles made the decision that they would kill even more prey than ever before to suck out the nutrients. And so, they decided that they would kill a white-haired succubus and a human man who had just wandered into the forest. As usual, the tentacles assaulted the man with thorned tentacles specialized for attacking. Unfortunately for them, he was able to easily brush off their attacks, and they barely managed to scratch the man's arms. At that moment, the succubus who was accompanying him became as furious as a raging conflagration, and vaporized all of the tentacles around them with a fire spell. This terrified even the tentacles, so they unintentionally allowed the man and the succubus to escape. The tentacle’s attack was a failure.

Later, perhaps the white succubus had called friends; dullahan knights, and a group of witches led by a baphomet appeared in the tentacle forest to cut it down, and raze it with flames. From the sky, the hellfire breath of a dragon rained down, and on the ground, the baphomet's great magic blasted the tentacle plants away along with the very soil. Those that had narrowly managed to escape were cut apart by the dullahans, and incinerated by the witches. I have heard that only half a day after the coming of this large group of monsters, the size of the tentacle forest had been reduced to a mere one tenth of its original area. This half a day of hell shocked all the tentacles of the mamono realm, and they stopped killing humans and monsters. It is said that they especially swore to absolutely never harm a human man.

In this way, the tentacles were at a loss for what to do, but then a spectacle witnessed by one of the surviving tentacles allowed them to find hope amid the despair. The monster soldiers rested in the empty land that was left after razing the tentacles and finishing their mission; they laughed and chatted with their comrades and the human men who had come to pick them up while having a meal. And then, a drunk dullahan tripped and dropped her head, going mad with lust; she started having sex with her own husband who had come to pick her up. By sucking up the thick demonic released from the monster having sex with the human man, the tentacle plant seeds that had been buried there in the ground unable to sprout sprouted. In this way, the tentacles at last became determined to coexist with monsters by providing couples with pleasurable, thrilling sex, and in return, having the monsters provide demonic energy for them. They changed into plants that survive by drinking it.
