Phantasmal Species

幻想種 - Gensoushu

Rather than a classification for a different kind of beasts, this is more of the common term used to refer to all non-human human creatures that are found in legends. Encompasses demi-humans, such as fairies and giants, and monsters, such as dragons and oni\ogres. Unlike the Devils, they are active and not passive existences.

Similarly on how the magi gain power through the accumulation of knowledge, those of the Phantasm Races become stronger through the accumulation of time. But while modern Magecraft is the sum of 500 years worth of study, the Phantasm Races dates back since the ancient times. A magus backed up by a mystical lineage that spans only 500 years cannot hope to mach the power of a mystery from the Age of Gods. Their powers are mysteries of a scale that cannot be reproduced by modern Magecraft and even their very existence is said to be already in par with Magic.

However the older theses mysteries become, the further away they are set from the rest of the world. A member of the Phantasm Races that reaches a level equivalent to a Phantasmal Beast will disappear into the shadows of the world. In the present era, only the members of the Phantasm Races whose age is are measured in centuries - and not in millennia – still remain.

Monsters
魔獣 – Majyuu

The common denomination for all creatures that do not fit in the ordinary biological classification for living beings, but nevertheless have bodies that are organically possible, as it is the case with most of the Phantasm Races. Their power increase with time and they advance in ranks once they reach a certain age. Said ranks are: Demoniac Beasts, Holy Beasts, Phantasmal Beasts and Divine Beasts. Holy Beast and Divine Beast ranks seem to be equivalent to Demoniac Beast and Phantasmal Beast, except for the fact that they are used only for creatures of celestial nature specifically. While it is still possible to find monsters living in uncivilized areas in the present age, those of high ranks have all but disappeared from the world.

Phantasmal Beast-level creatures cannot be harmed by the power of modern Thaumaturgy.

Blood-sucking Species
吸血種 - Kyuuketsushu

The general name of those that drink the blood of others. Includes Dead Apostles and True Ancestors, despite their human origin.

Blood Worms
吸血虫 - Kyuuketsuchuu

That what Matou Zouken became at the end of his life, a conglomerate of Crest Worms with a special appetite for human flesh and blood that combine themselves to take a human form. Despite the blood-sucking habits, it is not considered a true vampire.

Chimera
キメラ

These Demoniac Beast-rank creatures are the most common kind of monsters.

Divine Bulls
神牛 - Shingyuu

Divine Beasts-ranking animals, two of these creatures are part of the Gordius Wheel Noble Phantasm. Another different one was responsible for killing Gilgamesh's friend, Enkidu.

Dragon Kind
竜種 - Ryuushu

Regardless of their ranking, dragons are considered to be the greatest of the Phantasm Races. For summoning purposes, they are treated as being Phantasm Beasts-rank monsters. Creatures that generate prana merely by breathing, they possess traits from other types of monsters and have freely intermixed with humans in the past. Have yet to make a direct appearance in the Nasuverse, but it appears that one of those have once lived in Miongawa (the river that cuts through Fuyuki City) and taught martial arts to the monks of Ryuudouji as a hobby.

Einnashe
アイナッシェ

An 800 year-old sentient forest. The attributes of the forest were initially thought to be due to a Reality Marble, but the truth was that the forest matured to the level of a phantasm race by absorbing the blood of a Dead Apostle.

Fiendish Kind
鬼種 - Kishu

The Oni races of Japan. Creatures symbolized by inferno and scorching heat. The source of the inhuman blood in the Kishima and Tohno lines.

Gorgon
ゴルゴン

Medusa's incarnation as the legendary one-eyed man-eating monster, her role as a Gorgon would be decreasing mankind’s numbers.

Pegasus
天馬 - Tenba

These animals are docile creatures that are usually on the lowest ranks of the Phantasm Races.

The one summoned by Rider is a special case as it has been alive since the Age of Gods, and thus has already reached the level of a Phantasmal Beast. It possesses a defensive power in par with dragons and can easily withstand even attacks from Invisible Air. Still, due its kind nature Rider has to use Bellerophon to force it to fight.

Primate Murder
プライミッツ・マーダー

The beast of Gaia. The primate killer. A white beast. The hound of Altrouge Brunestud.

Unicorn
一角馬 - Ikkakuba

Demi-Humans
亜人 - Ajin

The general term used for the likes of fairies, dwarves and giants.

Fairies
妖精 - Yousei

There are various different types of those and they seemingly lack any sort of human values. Some have the power to interfere with people’s memories, while others are known to be able of crafting Noble Phantasm-level artifacts, with Avalon and Excalibur serving as examples. They are usually entities that cannot be seen by normal humans, however those who evolve into a magnitude where they can be perceived by people become Elementals.

The ones seen in Kara no Kyoukai are not true fairies, but rather lower-class spirits shaped after the image of fairies. Much weaker in terms of raw power, but share some of the abilities of the real ones due being created after their images.
