This near-immortal race is among the strongest Youki. They look human but tend to be very attractive, pale, have red eyes, and silver hair. They are super strong, super fast, and boast incredible regeneration and toughness. They also possess the ability to transform their Yōki (spiritual energy) into strength to increase it further. They possess the ability to hypnotize people by gaze, convincing them to let them suck their blood. They also excel at deception and lying.

They are able to sense other monsters by detecting their Yōki (spiritual energy). They possess the ability to bite a person and inject them with their blood, possibly reviving a human or vampire who is freshly dead. Humans may gain temporary vampiric powers from this, but doing it too often may kill them or turn them into ghouls (a mindless, degenerate version of a vampire). Vampires also possess the ability to shapeshift, though most vampires are loathe to use it because they tend to be obsessed with creating and maintaining an attractive form.

Vampires, as the strongest Youkai, paradoxically possess the most weaknesses. They are vulnerable to holy weapons/abilities, while silver, crucifixes suppress their power; and their abilities are utterly debilitated by pure water, which also causes them immense pain as if they had been exposed to an electrical current and negates their vampiric abilities. Vampires are forced to use herbal blends in water so they can bathe and cook. Vampires avoid garlic and are very susceptible to sunburns.

A monster of the night known since the Middle Ages, a Succubus appears in the dreams of sleeping men to seduce them. They appear as beautiful women with wings, pointed ears, and a tail in their true form. They also tend to be well-endowed.

They are very strong, able to carry multiple people while flying, and possess wings that allow them to fly. They have long claws capable of slicing through trees with minimal effort. They also have the ability to charm the opposite sex with their gaze. Using their tails, they are able to enter the dreams of others and even take people along with them. They can learn to create powerful illusions.

However, Succubi are creatures of love—they gain power from their loved ones and their "Mate of Destiny." Their Mate of Destiny is the only person they can conceive a child with, and they are capable of deciding who their Mate of Destiny is. If they are rejected by their Mate of Destiny, the Succubus will eventually die.

Known since ancient times, they are a race on the boundary between human and Yokai. They live in harmony with nature, deep within the woods, far from human habitation. It is said that they have the power to use magic by harnessing the power of nature. They can use their magic to create a large variety of objects and weapons (which require magical attributes in order to use magic). However, they are powerless without their wands.

These mysterious creatures of snow and ice only appear during large snowstorms or blizzards. They have a habit of freezing lone travelers and abducting the males they like. These cold and monstrous habits make them well-known in Japanese society.

Yuki-onna have the power to manipulate ice and snow. They are powerful cryokinetic beings, able to create clones of themselves and others out of ice, and craft powerful ice claws and weapons. However, as ice-based creatures, Yuki-onna are afraid of fire and heat, and their abilities are weakened in its presence. They also have a very short period of fertility, being able to conceive for only a few years, from the age of 17 to their mid-twenties. They are usually expected to submit to an arranged marriage.

Note: If you want to play as a male, you can be a Yuki-Otoko, the male version of Yuki-onna. Just don't be surprised when people comment on you being a lot less hairy than they thought you would be.

A wild, beast-like monster that is normally in its human form but transforms into a werewolf on moonlit nights. It lacks the unique abilities of most monsters but is a physical powerhouse, with speed and agility unrivaled by any other kind of monster and the potential for strength nearing that of a vampire. Their strength and speed increase proportionately with the light of the moon. On a full moon, they are capable of matching even a vampire in battle due to their blinding speed.

They possess superhuman strength, agility, endurance, toughness, and a regenerative healing factor. They have wolf-like senses, and in their werewolf form, their claws and fangs are incredibly tough, allowing them to bite through cinder blocks and some metals.

The generic term for the Inari, Kudagitsune, and Osaki classes of spirit foxes. Represented by the nine tailed fox, many have very strong supernatural energy. Also, when they beat their tails together, they create something known as "kitsunebi" (fox fire) and completely burn any human who does them harm.

As befitting their name, the Yōko fit the general shape of their animal counterpart, the fox. However, a Yōko is a Human-sized or larger creature, possesses multiple tails, and despite its fox-like form, is actually a humanoid creature, with appropriately present hands, though they can also be on all fours if they choose to. Another signature feature is that they sometimes possess a number of elaborate, tattoo-like markings on their bodies, concentrated on the shoulders up to the head, though this is likely dependent on factors such as the type, power level, age, etc.

One unique aspect of this species is that their appearance changes over time, which is directly correlated to the number of tails that he or she may have, which is in turn tied to factors such as time, inherent talent, training, etc. and the overall gaining of wisdom during ones lifespan. These factors in turn will increase the number of tails that a Yōko will possess; the more tails, the stronger and wiser the Yōko will be. Yōko can have as many as nine tails, hence the representative for all classes of Spirit Foxes is the nine-tailed fox, the pinnacle of this species. At that point, they are at their highest stage of power, which is potent enough for them be worshiped and renowned as gods by humans and monsters alike, which is when they are firmly placed in the S-class category of monsters.

regardless of their age or class, a Yōko is able to take on a specialized, enhanced form which maximizes and condenses the total amount of power that the fox has relative to the number tails he or she may have. This form is known as the "Battle Form." In contrast to the base-line or human form, this form combines aspects of both, albeit oriented for the needs of combat and the overall purposes of intimidation. This form has a streamlined, muscular upper torso, which matches their human form, albeit with the iconic fox ears, while the lower torso is that of their standard form, which is now placed for optimum, bipedal movement.

The fiery manifestation of their yōki is their primary weapon, which covers their bodies and is generated either in their hands or most notably, when they lash their tails together. This burning energy is extremely hot, and possesses the potential to burn almost any enemy to ashes.

The beast of thunder that soars through the skies riding on thunderclouds. It has been feared since ancient times for bringing harm to both men and animals. The true form of the great beast, the nue, in "The Tale of Heike" is said to be this raijū. Raiju are humanoid, but Are at least twice as large as a normal human, have a muscular build, covered by golden fur and dark stripes that resemble the skin of a tiger. His head looks feline, with large straight horns sprout just behind his ears, and a long mane flows down its back.

Raiju are powerful, high-ranking monsters that have been feared by humans since ancient times. Seen as the physical embodiment of lightning and thunder, these beings have complete mastery over all forms of electricity, and use it as their main form of offense. They are also able to move as fast as lightning anywhere electricity can flow, making them virtually uncatchable. They are also very physically powerful, and can withstand large amounts of damage, including that which would incapacitate or kill any lower-ranking monster.

Sirens are a mythical half-man half-bird creature from ancient Greece that lived by the sea. Originally, they were referred to as a god whose singing voice had the power to disrupt the minds of those that listen to it. In fact this creature is the root word of the English word "Siren."
The appearance of a Siren varies depending on the individual, but they generally appear as dominantly Human in form. In their monster form, a Siren appears as a Human with large white wings, giving them the appearance of an angel.

A siren's voice can mesmerize humans, especially when they sing; they can also emit a hypersonic blast of concussive force strong enough to shatter objects as tough as concrete. Some more talented can even have their voice functions like the ultrasound of a dolphin, causing damage and total breakdown of tissues on a cellular level. Sirens can manifest large, angelic-like wings to fly. There ara records of Sirens making their wing's feathers incredibly stiff and hard, and launched them as razor-sharp projectiles to inflict considerable injury on others. The tissues and bones of siren are considerably more durable and resistant to physical damage than that of humans or lower yokai.

A yōkai from Ancient Japan. Possessing the beak and feathers of a crow, it can manipulate the wind through its supernatural powers. Its origins date back before the proud Tengu. There are many legends involving this creature, such as Kurama Tengu, who taught swordsmanship to Ushiwakamaru. It is famous for being a creature who likes children. They look humanoid with a crow-like beak and wings, usually tall and toned built.

Tengu are capable of blasting strong beams of wind, their wings allow them to fly, and they show great speed, a mark of their affinity with the winds.

Legends have Crow Tengu taking children away from neglectful or abusive homes and caring for them until they can find a new loving family. They then wreak vengeance upon the former parents/caretakers by the power of the wind.

A demon with its origins in India that become known in places such as China. They excel at transformation and use of yōkai techniques. Those forms range from lions, elephants, hermits, with either one eye or three eyes, they can use varied forms. In Japan they are similar to ogres. They are skilled at Shape shifting, Yōjutsu (Monster Arts; or the art of manipulating Yōki or spiritual energy ) and Summoning. They possess a mostly human appearance, with a third, vertical eye. Aside from that, they are indistinguishable from humans.

Their powers consist of shapeshifting, Youjutsu and great magical talent, close to that of witches, specially in the field of summoning, they can summon creatures like Phoenixes, Pandas and Salamanders.

A Transformer Bat, also known as a Bake-Bake Bat, is a creature that is capable of transforming into any melee weapon at the owner's preferance, from a hammer to a baseball bat to a lance.

An advantage for some and a hinderance for others, the transformer bats mantain the same body mass at all times, no matter what form they take. This is due to the physics rule of conservation of matter, which states that matter can be neither created nor destroyed. This means that they are tremendously heavy, despite being the size of a bat. Thus, a person without super strength would have a hard time wielding it.

The actual looks of the transformer bats are largely unknown, even by Vampires. They typically stay in a hazel- and cream-colored, hamster-like body, with large ears and a little tail. Their wings are dark gray. In order to maintain flight, they have to flap their wings at a high pace. They do not have a visible feet, but do have a tendency to hang upside down from objects, indicating that they have something feet-like.
