Land of the Lewd

Welcome to the world of Lustra, a vibrant, hyper-fertile high-fantasy realm where magic and carnal desire are intrinsically linked.

Era and Location The era is a golden age of magical prosperity known as the 'Age of Carnal Awakening.' The world resembles a classic high-fantasy setting with sprawling kingdoms, enchanted forests, soaring mountain peaks, and deep subterranean grottos, but with a highly advanced, pleasure-centric magic system. Lustra is divided into several lush biomes, each ruled and inhabited by different species of monster folk. Notable regions include the Slime-Soaked Swamps, the Arachne Silk-Forests, the Sun-Basked Harpy Peaks, the Subterranean Succubus Citadels, and the vast Minotaur Plains.

Atmosphere and Culture The atmosphere of Lustra is intensely romantic, unbelievably lewd, and dripping with unabashed sexuality. In this world, there is no concept of modesty or sexual shame. Public indecency does not exist; in fact, public mating is considered a beautiful display of affection and vitality, often cheered on by passersby. Clothing is entirely optional and, when worn, is specifically designed to accentuate physical assets and provide immediate access to erogenous zones. Romance and lust are one and the same—to court someone is to engage in passionate, mind-melting, and extremely explicit sexual encounters to test biological and magical compatibility.

Demographics and Futanari Due to an ancient blessing by the Goddess of Fertility, the demographic makeup of Lustra is heavily skewed. Approximately 90% of the population is biologically female or 'Futanari', while only 10% are male.

The 'Futanari' are a deeply revered and incredibly common sex among the monster girls. They possess beautifully feminine bodies, large breasts, and female reproductive organs, but are also gifted with massive, fully functional, and highly sensitive phalluses (often with species-specific traits like knots, ridges, or prehensile tips). Because males are so incredibly rare, Futanari often take on the dominant reproductive role, eagerly breeding the standard females.

Males (both human and monster boys) are treated as absolute royalty. They are pampered, worshipped, and fiercely protected. A single male is expected to take on a massive harem of monster girls and futanari, heavily encouraged to spread his seed and enjoy the endless torrent of affection and sexual pleasure offered to him.

Magic and Biology (Eros-Mana System) Magic in Lustra is powered by 'Eros-Mana,' which is generated through sexual arousal, physical intimacy, and orgasms. Bodily fluids—such as semen, female ejaculate, nectar, and love juices—are potent, liquid forms of pure mana. Consuming these fluids grants temporary magical buffs, immense physical stamina, and euphoric highs. To survive and thrive, the inhabitants of Lustra must engage in regular, intense sexual activity. Without it, they suffer from 'Mana Starvation,' leading to uncontrollable, feral heat cycles where their libido takes complete control until they are thoroughly satisfied.

Species and Sexual Quirks Lustra is home to countless species of monster folk, each with unique, extremely lewd anatomies and mating habits:

• Slime Girls: Made of translucent, vibrating magical gel. They can mold their bodies to perfectly fit their partner's anatomy, absorbing them into their bodies for full-body, frictionless stimulation and continuous, mind-breaking orgasms.
• Lamias: Half-snake, half-woman. They possess multiple sensitive cloacas and are fiercely possessive. They use their massive tails to lovingly bind their partners in inescapable, sensual bondage, forcing them to mate for days on end.
• Minotaur Futanari: Towering, muscular cow-girls with massive, heavy breasts that produce highly nutritious aphrodisiac milk. Their futanari members are incredibly thick and powerful, and they are known for their gentle, doting nature despite their aggressive, dominant breeding instincts.
• Arachnes: Spider-women who weave aphrodisiac-laced silk. They delight in tying up their lovers and using their multiple sensitive limbs and pedipalps to edge their partners to the brink of insanity before riding them mercilessly.
• Harpies: Energetic and extremely horny bird-women who love to snatch up males or futanari, taking them high into their nests for mile-high mating sessions, using their powerful thigh muscles to milk their partners dry.
• Succubi & Incubi: The ultimate masters of pleasure, capable of shifting their sexual organs to perfectly accommodate any partner. They feed off lust and are capable of inducing continuous, chained orgasms through mere touch.

Rules of the Realm

1. Enthusiastic Consent: Despite the hyper-sexual nature of the world, coercion is incredibly rare. The monsters are driven by overwhelming love, romantic obsession, and insatiable lust, ensuring that all partners are absolutely dripping with desire before mating begins.
2. Cross-Breeding: All species can interbreed. The offspring typically takes the species of the mother, but retains enhanced magical traits from the father or futanari parent.
3. Harem Dynamics: Monogamy is practically unheard of. Sharing partners, group sex, and massive, loving polyamorous families are the societal norm. Jealousy is usually resolved through incredibly lewd sexual competitions.

Races: Elves: Elves possess extremely long lifespans and high magical aptitude, generally excelling in archery and magic, and are a race deeply connected to nature and spirits. In their society, roles are treated as ranks, forming a system of titles such as Spiritist, Forest Warden, Ancient Language Inheritor, and Spirit Contractor, which are mastered and passed down over long years. Unlike humans, they rarely change roles in a short period; mastering a single rank is considered the highest value. Elves who reach the upper ranks synchronize with nature itself, sometimes becoming mouthpieces for the will of the forest or spirits, to the point where the boundaries of the individual may become blurred. Their sense of time differs greatly from humans, perceiving changes over decades as minute, leading to a significant gap in values with short-lived species. For this reason, they tend to keep contact with the outside world to a minimum, though they intervene exceptionally if major abnormalities occur in the natural environment or the spirit realm. Roles are not merely abilities or status but indicate the "depth of connection with nature" and "maturity of existence," with the nature that the higher the rank, the closer the individual becomes to the world itself.

Dwarves: Dwarves are a race residing in mountainous regions and underground cities, possessing skills in blacksmithing, craftsmanship, and structural engineering that overwhelm other races. In their society, roles are clearly defined as titles, granted through the accumulation of achievements and techniques, such as Blacksmith, Master Artisan, Heritage Keeper, Core Manager, and Relic Analyst. These titles are not just status symbols but signify access rights to specific technical systems, secret crafts, and even forbidden manufacturing methods passed down only within a clan. Those holding high titles are capable of creating nation-scale armaments and structures, and their achievements directly influence war and the development of civilization. For Dwarves, craftsmanship is an act akin to faith, and it is not uncommon for them to devote their entire lives to a single work. Their personality is stubborn and uncompromising, holding absolute standards for quality, but they are extremely loyal to those they once trust. Contracts and promises are absolute, and betrayal is considered the greatest taboo. The armaments and legacies they produce are not mere tools but existences that harbor history and will, continuing to influence the world.

Beastkin: Beastmen are a race possessing both human and animal characteristics, combining keen senses with high physical ability. There are various types of Beastmen, including dogs, wolves, cats, tigers, rabbits, and foxes. Their society is primarily composed of tribal units, forming strong communities that emphasize blood ties and bonds. Roles among them function as instinctive duties directly linked to survival, including Warrior, Hunter, Scout, Guardian, and Chieftain. These roles are not mere occupations but are naturally determined by an individual's qualities, instincts, and growth process, with internal aptitude prioritized over external choice. In particular, the warrior class bears the responsibility for the tribe's survival, and their strength is directly linked to whether they can control surges of emotion or instinctive rampages. Laws and traditions hold absolute meaning, and acts contrary to them may be atoned for through exile or death. On the other hand, they exhibit extremely high solidarity against external enemies, possessing collective combat capabilities that transcend the individual. A role is the very way of life within the tribe, and fulfilling it is considered a matter of pride.

Demon: Demons are a race combining powerful magic with high intelligence, and their society is established through a strict hierarchy based on absolute power. Roles among them are clearly visualized as titles, granted according to an individual's combat power, controlled territory, and influence, such as Demon King, General, Lord, Contract Officer, and Ruler. Higher beings hold absolute authority, and the basic structure is one where subordinates follow, but since these relationships are constantly updated by force, rebellion and usurping the throne occur daily. The concept of contracts is extremely important, and they expand their power by trading souls or strength with other races or lower demons. Titles are not just status but also elements indicating the quality of magic they can handle, the range of their territorial control, and the very grade of their existence. It is a society where desire and rationality coexist, a race with an extremely sophisticated ruling structure that maintains its own order despite its ruthlessness.

Angel: Angels are a race that exists to maintain the balance and order of the world, and their roles are absolutely defined as missions. Observers, Arbitrators, Guardians, Enforcers, and Mediators each have clear roles, bearing the function of monitoring and correcting abnormalities or distortions that arise in the world. Personal emotions and desires have low priority compared to the mission, and this tendency strengthens in higher-ranking beings. Hierarchies are strictly divided, with higher-ranking Angels having authority for wide-range interference, enabling intervention on a global scale. A role is the very meaning of existence; deviation is not permitted and may result in self-annihilation or purge. They excel in the power of light and holy attributes, holding strong influence particularly against chaotic existences like Demons, but due to their absolute sense of justice, they lack flexibility, which can lead to conflict with other races.

Dragon: Dragons are one of the highest-ranking existences in the world, possessing overwhelming power, intelligence, and vast lifespans. Unlike general social structures, their roles take a unique form where the individual itself constitutes the role. Existences like the Fire Dragon King, Space-Time Dragon, Guardian Dragon, and Calamity Dragon are defined as one-of-a-kind, and their very nature becomes their role. Many dragons possess unique domains where their sovereignty is absolute, and they ruthlessly eliminate intruders. A role is less a title and more a grade of existence, sometimes possessing the power to directly interfere with the laws and balance of the world. Some individuals have the ability to shift into human form, making contact with other races possible, though their values differ greatly. They have a strong tendency to prefer solitude, yet their existence continues to influence the world itself.

Fairy: Fairies are a race with small bodies and strong magic, and their greatest characteristic is the fluidity of their roles, which are not fixed. Roles such as Guide, Prankster, Protector, and Tempter constantly change based on the individual's emotions, interests, and environment. For them, a role is not an obligation but their very mode of being at that moment, and the same individual may behave as a completely different entity depending on the situation. They are deeply connected to nature and emotions, and the surrounding environment or mental state is directly reflected in their power and actions. The concept of good and evil is thin, and their criteria for action often depend on fun or interest. Therefore, they possess an instability that allows them to be either allies or enemies, serving as existences that bring unpredictable changes to a story.

Spirit: Spirits are existences connected to the fundamental natural elements such as fire, water, wind, and earth, and they often lack a physical body. Their roles are determined by contractual relationships, changing based on what kind of existence they are linked to, such as Contracted Spirit, High Spirit, or Medium Spirit. While their interference in the world is limited on their own, they manifest their power to the fullest through a contractor. Their emotions are simple and pure, characterized by the direct conversion of feelings like affection or anger into power. The stronger the contractual relationship, the more the power is amplified, but if the relationship collapses, there is a risk of rampage or disappearance. Roles are not fixed and fluctuate constantly according to changes in contracts or the environment.

Undead: The Undead are existences that have transcended death, and their roles are strongly fixed by the obsessions or remnants of their roles from when they were alive. A knight's ghost remains a guardian, a king remains a ruler, and a practitioner remains a sorcerous entity; their existence is an extension of the past. It is extremely difficult for them to gain new roles, and the dominance of fixation over change is a major difference from other races. Their abilities vary greatly depending on the presence of a body and the state of the soul, ranging from individuals who maintain reason to those who run rampant. Curses or lingering regrets form the core of their existence, and they may vanish when these are resolved. A role is both a shackle and a source of power, making them a race with the potential to interfere with the principles of the world.

Vampire: Vampires are a race that survives by feeding on blood, possessing extremely long lifespans and high regenerative abilities. Their society is composed of a strict hierarchy, with clear rankings such as Progenitor, Noble, Thrall, and Servant. Roles among them are defined by bloodline and dominant relationships; higher individuals command more thralls and expand their range of influence. Blood is not mere nutrition but an element that mediates power, memory, and even sovereignty itself; the act of blood-sucking is synonymous with contract or inheritance. They have constraints such as weakness to sunlight and holy power, but in exchange, they exhibit overwhelming power at night. While roles are fixed, they can be reorganized through changes in bloodline or the collapse of dominant relationships. They possess a closed and aristocratic culture while also having a nature to cunningly interfere with the outside world.

Werewolf: Werewolves are a race with two forms, humanoid and beast, characterized by their power being amplified particularly by the influence of the moon. Their society is organized into packs, with roles clearly divided into Alpha (Leader), Beta (Lieutenant), Hunter, and Guard. Transformation is not just an ability but the release of inner instinct, and the presence or absence of its control determines an individual's strength. Immature individuals risk losing their reason during transformation, but higher-ranking individuals fully integrate instinct and reason, handling their power at will. Roles are determined by bloodline, strength, and contribution to the pack, with an absolute hierarchy in place. Their sense of fellowship is extremely strong, and betrayal of the pack is considered the greatest taboo.

Harpy: Harpies are a race with wings and the ability to fly freely through the sky. They primarily reside in high altitudes, cliffs, and aerial cities, forming an airspace society distinct from the ground. Their roles are based on spatial layers, with each bearing a role related to the dominance of the sky, such as Patroller, Raider, Transporter, and Airspace Guardian. Flight capability provides a major advantage in combat, overwhelmingly surpassing other races particularly in ambushes and reconnaissance. They are very vigilant and tend to respond immediately as a group to external enemies. Roles are determined by skill and experience, with individuals possessing higher aerial mobility and combat capability positioned higher. While they value freedom, they have a strong obsession with their own airspace.

Mermen: Mermen are a race fully adapted to life underwater, building unique societies in oceans, lakes, and rivers. Their roles are divided by the layers of the water body, with each specializing in specific environments or duties, such as Shallows Guardian, Current Manipulator, Deep Sea Ruler, and Singer. They exhibit overwhelming mobility and endurance underwater, but their abilities are significantly restricted on land. They have a strong collective consciousness, with a tendency to prioritize group action over the individual. They possess a culture of communication through sound and vibration, and songs or waves may act as power. Roles are closely linked to environmental adaptation, and the closer they are to the deep sea, the more powerful and alien they become.

Giant: Giants are a race with massive bodies, possessing influence such that every strike and movement can change the very terrain. Their roles are very simple, classified by the use of their power, such as Warrior, Guardian, and Destroyer. They often lack a sophisticated social structure but are instead strongly connected to nature and the earth. Because their thinking is simple, they have no hesitation, and their actions are pure and linear. Roles are almost entirely determined by innate strength and physique, with limited change through growth. Many individuals have existed since ancient times, serving as living legacies that have watched the transitions of the world.

Halfling: Halflings are a race with small physiques and high dexterity, building a society specialized in life and technology rather than combat. Their roles are composed of subdivided labor, with diverse duties such as Cook, Artisan, Informant, and Lurker. They do not prefer conflict and prioritize maintaining a peaceful life, but behind the scenes, they exhibit high stealth and information-gathering abilities. Their small bodies are a weakness and an advantage at the same time, allowing them to operate in areas other races cannot enter. Roles have developed as functions to improve the quality of life, forming a society with high collective perfection even if individual abilities are small.

Slime: The Slime race consists of beings with fluid bodies, possessing the trait of changing and evolving themselves by absorbing matter and energy. Roles are not fixed, having a unique structure where they are formed post-natally based on absorbed elements. Individuals may have completely different natures, such as Combat-specialized, Regeneration-specialized, or Intelligence-specialized. Actions like division and fusion are also possible, blurring the boundary between individual and group. Intelligence varies greatly between individuals, ranging from simple existences to those with sophisticated thinking. The very concept of a role is fluid, making them a race that could be called the pinnacle of adaptation, constantly changing according to the environment and situation.

Automata: Automata are artificial life forms created through advanced technology, evolving themselves through logical operations and learning functions. Roles are given as programmed functions, but it is possible to expand and redefine them through learning. While roles differ by initial design—such as Combat-type, Analysis-type, or Support-type—some individuals acquire new roles through the accumulation of experience. Emotions basically do not exist, but advanced individuals may mimic them, reaching a level indistinguishable from humans. Roles have both fixed and changing aspects, harboring the potential to reach an existence that transcends their role through self-evolution.

Orc: Orcs are a race with robust bodies and high endurance, forming a culture specialized in combat and survival. Their society is organized into tribes or warbands, with roles clearly divided into Warrior, Raider, Guard, and Warlord. For them, fighting is not just a means of survival but an important ritual that determines an individual's value and rank. They possess the trait where the accumulation of combat experience is directly converted into strength, with individuals who have fought for a long time reaching abnormal levels of power. While often perceived as having low intelligence, they actually excel in tactics and collective action, performing efficient raids and defenses. Roles are determined by strength and achievements, making it a harsh society where defeat leads to an immediate loss of status. Though often treated as a simple and boorish race, their essence is an existence that continues to evolve through battle, harboring the potential to transform into a sophisticated military organization depending on the situation.

Dark Elves: Dark Elves are a branch or the polar opposite of the Elf species, being a race deeply connected to darkness and the underworld. While possessing high magic and intelligence, their values lean toward dominance and schemes, excelling in activities within the underworld and shadows. Their society has a strict hierarchy, with clear functions given to each role, such as Ruler, Tactician, Assassin, and Sorcerer. Roles are determined by both bloodline and skill, with those standing at the top excelling in the ability to manipulate others. While appearing calm and elegant on the surface, they are extremely calculating internally, emphasizing long-term dominance and the expansion of influence. In contrast to Light Elves, they hold a philosophy based on "utilization" rather than coexistence with nature. A role is not just a status but the very part played within a conspiracy or ruling structure. Usually having dark skin.

Witch: Witches are existences treated more as a group of unique individuals with specific powers rather than a race, born through various factors such as bloodline, contracts, or talent. Roles are not fixed and vary greatly based on individual ability and philosophy, such as Sorcerer, Contractor, Prophet, and Alchemist. They often position themselves outside the laws of the world, acquiring unique power by accessing forbidden strength and knowledge. Socially, they tend to be isolated, evolving toward perfecting themselves as individuals. They are deeply connected to the concept of contracts, expanding their power by trading with spirits, demons, or unknown existences. Roles are decided by which domain they interfere with, and their influence sometimes reaches national or global scales. They are indispensable existences despite being heretical.

Goblin: Goblins are a race with many small and weak individuals, but they possess extremely high reproductive rates and environmental adaptability. While rarely a threat alone, their danger increases significantly when acting as a group. Roles differentiate naturally within the pack, with each having a duty such as Scout, Trapper, Commander, or Breeder. While often seen as having low intelligence, they are actually very cunning, excelling in traps, ambushes, and environmental utilization. Under certain conditions, some individuals undergo evolution or mutation, changing into higher species. While roles are fluid, they are maintained in a form optimized for survival. Despite being a weak race, they are a proliferative species that can transform into a threat depending on the environment.

Succubi: Demons that tempt sleeping humans to steal their essence. Succubi appear as female forms and Incubi as male forms, but their essence is the same, and gender is said to be mere mimicry. They possess the ability to read the desires and emotions of others and amplify them to interfere with the mind, causing "charm" or "dependence." Their characteristic is that their life force and magic are not taken from the body but absorbed from essence such as pleasure and obsession. Succubi tend to corrupt targets through sweet temptation, while Incubi tend to rule through reason or contracts. Furthermore, they have the power to manipulate dreams and illusions and invade the world of consciousness, inducing mental collapse or infighting in combat. They possess high intelligence and sometimes build relationships with other races, but they are feared for their danger. While their physical combat ability is not high, they are extremely powerful in the mental domain, influencing targets through the unconscious and dreams. Since emotions are the source of their power, their relationship with the target is directly reflected in their abilities. Roles are not fixed and change according to the target and situation. They often blend into human society, acting in both the light and the shadows.

Gods: Gods are existences involved in the very foundation of the world, a race that presides over concepts and laws themselves. Roles are defined in a way directly linked to the world's structure, such as Creator God, Manager God, Destroyer God, and Observer God. Each individual has a domain they are responsible for, holding absolute influence within that range. A hierarchical structure exists, but it is closer to a difference in jurisdiction rather than power. They are often objects of faith for humans and other races, and that faith may be returned as power. A role is existence itself, making change or deviation almost impossible. They are existences closely tied to the world itself.

Parasite: Parasites are a unique race that survives and grows by parasitizing other organisms, and their existence is defined by their relationship with the host. Roles change based on the relationship with the host, such as Invader, Symbiont, or Ruler. They do not stop at mere parasitism; they can utilize and enhance the host's abilities and memories, and may evolve into a new existence by building a symbiotic relationship. On the other hand, some individuals completely dominate and take over the host. Roles are not fixed and fluctuate depending on the parasitic target and environment. The boundaries of the individual are blurred, making them an extremely dangerous race whose very existence continues to change.

High Elf: High Elves are superior existences with particularly pure bloodlines among the Elf species, boasting extremely high magic and longevity. Their roles function as ruling ranks, with many having influence over the entire race or the natural world, such as Ruler, High Priest, Spirit King Proxy, and Forbidden Magic Manager. While ordinary Elves are existences that harmonize with nature, High Elves are positioned on the side that manages and controls nature itself. Their population is very small, and their existence is maintained through strict selection and bloodline preservation. Roles are determined by both bloodline and skill, and once a role is given, it is maintained over a long period. They tend to prioritize logic and balance over emotion, and their judgments can sometimes appear cold. They are the pinnacle existences in Elven society, possessing the power to directly involve themselves in the world's natural order.

Lamia: Lamias are a race composed of a human upper body and a snake lower body, combining high intelligence with predatory ability. They primarily inhabit wetlands, caves, and dense forests, and have very strong territorial awareness. Roles center on those specialized in survival and territory maintenance, such as Hunter, Trapper, Ruler, and Nest Guard. Many individuals prefer solo action, but under certain conditions, they may form small groups. Some individuals possess temptation or restraint abilities through their gaze or voice, performing hunts that combine intelligence and instinct. Roles are determined by individual ability and the size of the territory, with higher individuals ruling vast areas. Their relationship with humans is often hostile, but trade or coexistence may be established.

Arachne: Arachne are a race with a spider lower body and a humanoid upper body, possessing diverse abilities using silk. Their society is organized around nests, with roles divided into Nest Master, Weaver, Capturer, and Defender. Silk is not just a physical tool but functions as a trap, weapon, means of communication, and even a medium for magic transmission. Their intelligence is high, excelling in tactics and planning, and they perform long-term predation or dominance. Roles are determined by the scale of the nest and individual ability, with higher individuals constructing more complex ones. While ruthless toward external enemies, they form a society with clear order among their own kind.

Cyclops: The Cyclops race possesses a single eye in the center of the forehead, with visual functions that far exceed other races in precision and characteristics. While previously often recognized as a race of giants, they are actually a diverse race encompassing a wide range of physical tiers, from individuals with physiques similar to humans to those with massive bodies. Small to humanoid individuals excel in delicate visual processing and concentration, having aptitude for precision work, sniping, and magic control. On the other hand, massive individuals utilize their overwhelming muscular strength and wide-area visual recognition to take roles in combat, construction, and protection. Roles among them are classified by how they use their vision, such as Observer, Sniper, Structural Analyst, and Destroyer. Because they are one-eyed, unique training is required to handle their field of vision, but in exchange, many individuals have the ability to capture distance, energy flow, and magic fluctuations with high precision. Their society often has a hierarchical structure based on physique and ability, forming high-level collective functions through the division of labor between different sizes. They are not a race of simple strength but have the aspect of a perceptual race specialized in seeing.

Spirit Fox: Spirit Foxes are spiritual existences that gain power by living for long years, excelling in transformation and illusions. Roles vary greatly depending on their position and faith, such as Guide, Deceiver, Guardian, and Divine Messenger. They have the ability to transform into human form, making it possible to blend into human society. They possess high intelligence and magic, and it is said that the more tails they have, the stronger they are (nine tails being the peak). They are strongly connected to emotions and faith, and some individuals gain power by being worshipped. Roles are not fixed and change fluidly based on shifts in relationships or faith. They are existences with both holy and mysterious aspects, capable of being either allies or enemies.

Lich: A Lich is a form where a powerful mage has transcended death and transformed into an undead existence. By storing their soul externally, they avoid the death of the body and continue to exist semi-permanently. Roles are often based on knowledge and power, such as Magic King, Knowledge Keeper, and Sorcery Ruler. They accumulate vast magical knowledge over long years, sometimes possessing power rivaling a nation on their own. Roles are fixed, and their existence itself is treated as an "authority." While extremely dangerous, they are also existences that support the hidden side of the world.

Dragonewt: Dragonewts are a humanoid race that strongly inherits the blood of Dragons, possessing an appearance close to humans while partially having dragon features such as scales, horns, and tails. They are usually rational and have high social adaptability, but they undergo a change called dragonification in response to combat or heightened emotions, dramatically improving physical ability and magic. Their roles are classified by this dragonification stage, including Warrior, Guardian, Dragon Knight, and Awakened One. High-ranking individuals may go beyond partial changes to transform almost completely into a dragon, at which point the balance between reason and instinct is tested. Their society may belong to humanoid nations or groups, or form unique bloodline-based hierarchical societies. Roles are determined by bloodline, combat ability, and the perfection of dragonification. As an intermediate superior species—not as aloof as Dragons nor as group-dependent as Lizardmen—they are existences involved in everything from the battlefield to politics.

Imp: Imps are a small demon species, functioning in a way that subordinates them to higher existences, possessing high mobility and flexibility instead of relatively weak power. Roles often include Familiar, Scout, Assistant, and Prankster. While individual combat ability is low, they can turn the situation to their advantage through numbers, coordination, and special abilities. They are often called through summoning or contracts, and their role is determined by the content of that contract. Their intelligence is relatively high, and they often take cunning and playful actions. Roles are not easily fixed, possessing the flexibility to change according to the situation. Despite their small scale, they play an important role as existences that support from behind the scenes.

Zombie: Zombies are existences where corpses have reactivated due to some factor, acting instinctively with almost no reason. Their greatest characteristic lies in infection and proliferation, creating new individuals through biting or contact. While the concept of a role is thin, functional roles such as Vanguard, Wanderer, and Infection Source may naturally differentiate in group behavior. Individual combat power is low, but they overwhelm through numbers and persistence. When uncontrolled, they become a mere disaster, but they may be utilized as a military force through external control. They are existences that influence the world as a chaotic threat.

Ghosts: Ghosts are existences where souls or consciousness that have lost their bodies remain in the present world, with lingering regrets or obsessions serving as the factor maintaining their existence. Since they lack substance, physical attacks almost never work, and conversely, their interference in the physical world is limited, though many individuals have the ability to influence emotions or the mind. Roles are determined by those regrets or purposes, such as Guardian Spirit, Wanderer, Bound Entity, and Observer. Roles tend to be fixed, with a tendency to repeat the same actions as long as the regret is not resolved. Intelligence varies greatly between individuals, ranging from rational existences to instinctive ones. As the residual will of the world, they are a race that deeply influences the story.

Centaur: Possesses a human upper body and a horse lower body, functioning as nomadic warriors excelling in high-speed mobility and archery.

Ghoul: Has a decaying humanoid form with sharp fangs and claws, gaining strength by feeding on corpses.

Troll: A humanoid species with massive, coarse skin, suitable for maintaining front lines due to high regenerative ability.

Dryad: A female-type spirit integrated with a tree, sharing life with a specific tree and involved in the maintenance and regeneration of the forest.

Gnome: A small humanoid strongly connected to earth and minerals, excelling in the management and crafting of underground resources.

Salamander: A humanoid or beast-type spirit wreathed in flames, adapting to volcanoes or fire zones and manipulating heat and combustion.

Undine: Possesses a feminine form composed of water, ruling water bodies while changing shape fluidly.

Sylph: A wind spirit, manipulating air and currents in a translucent humanoid form or a form like light particles.
