A Humanoid or Demi-Human, is a blanket term for any partially Human race in the Special Region that are sapient and sentient, including elves, goblins, and various races with animal-like characteristics, such as Warrior Bunnies, Cat-Persons, Medusas, etc.

It is not clear how the humanoid minorities in the Special Region are related to humans in the region or from Earth. However, given Zorzal El Caesar discussing the possibility of impregnating Tyuule with a half-breed child and Delilah's mention of Warrior Bunnies breeding with males of other races, at least some of the races would be considered humans based on the biological species concept (which states that members of the same species can breed and produce viable offspring). This would suggest that at least some of the humanoid races would qualify as no more than subspecies of humans. Regardless of their relation to humans of the Special Region, humanoids are often viewed as inferior, despite some species show some superior traits than human like the Warrior Bunnies with their superhuman strength and speed or the Elves with their superior spirit magic. The Empire, in particular, are known to commit acts of genocide or enslavement towards humanoid races, though some, such as the late head of the Formal Clan was kinder to humanoids, and it is only because he found them aesthetically appealing.

According to Mimoza, the humanoids of the Special Region entered the region from the Gate during past periods of its opening.

Due to the Empire's influence, there are cases where for heroic feats are distorted due to how the desire for a human hero is very strong in the Empire, as noted by Grey Co Aldo while disregarding the achievements done by humanoids. This was seen when people were misinformed into thinking that Lelei La Lalena was the one that finished off the Flame Dragon, and not Tuka Luna Marceau, a fact that had nettled Lelei to a degree.

Demi-human's positive feelings toward Japanese's treatments, unlike the Imperials.

Because of the mistreatment of the Empire toward demi-human races, the majority of intelligent demi-human species like Elves, Dark Elves, Volraden, Tiger Men, Four-arm tribe or Dwarfs prefers to be JSDF's collaborators and allies as the Japanese treats them with more respect and tolerant. This fact enable the JSDF to have large division of Demi-human mercenaries at their disposal in Alnus. Demi-human species with feral nature and low intelligence like Orcs, Goblins or Ogres never being part of the JSDF as they are too dumb to realize that the JSDF treats them better.

The Haryo tribe, which consists of outcast demi-human races strongly opposes the JSDF due to their action of protecting royal and government collaborators, the people that the tribe wants to dispose off to gain power in Falmart.

The only major exception to demihuman mistreatment are the winged Avi of the Avion Sea. These are given preferential treatment due to their role as ship Guardian Protectors, ranking them second or third in most command hierarchies.

Humanoid races, with lengthy lifespans, were greatly envied by humans to the point where it became common for elves to be hunted down so they can be experimented; the defunct Kingdom of Arrun is one human nation discovered to have a research facility that conducted such researches on corpses of Dark Elves that were imprisoned for experimentation.

Generally Human

Generally human in shape with only minor differences such as size, ears, eyes, or number of limbs.

Elves

The Elves of the Special Region are similar to depictions of elves in 'high fantasy' fiction, being depicted as humanoid creatures with unique pointed ears and dashing appearances. Elves are known as expert archers and are also skilled in the use of spirit magic. Elves possess extreme longevity; routinely living for over 300 years, though are vulnerable to death by intense physical injury like humans. While they are nominally within the territory of the Empire, their relatively isolated villages in mountains and dense forests mean that they are, for the most part, de-facto independent. The Empire, for their part, have an undesirable attitude towards elves.

Dark Elves

Dark Elves are a sub-race of elves with brown or blue colored skin, who seem to live in colonies separate from their fair-skinned counterparts. However, it seems that there are some interactions between the two races, as Yao Ro Dushi may have met Hodor Marceau, and at least knew of Tuka Luna Marceau and the fate of her village. The Dark Elves is one of JSDF 's strongest allies as they indebted to Itami and the JSDF for getting rid of the Flame Dragon and it offspring.

Lennon

Lennon are a Humanoid race with a third eye on their forehead. Isla De Pinos is a member of this species/race.

Orcs / Trolls and Goblins

Goblins are sometimes referred to as "Orcs" or "Trolls". They are large and muscular humanoids with gray, green, or purplish skin and pig/ape-like faces. They are known to have a violent temperament and durable resistance to injuries. The Goblins appear to be vassals of the Empire and provided auxiliary troops during the Battle of Ginza and Battle of Alnus Hill. Goblins are very strong but appear to be less well-armed and armored than humans or other soldiers, carrying mostly crude clubs, warhammers, axes and cleaver-like swords. At least one is seen carrying a sword similar to an Imperial sword, possibly taken off a fallen soldier. Due to their feral nature and dim-witness, they don't ally themselves with the JSDF and often being used by Imperial army as meatshields, despite their absolute uselessness against the JSDF's firepower.

Ogre

Ogres are very large and violent humanoids. Zorzal has a few of them in his army and forged strong armor for them to resist gunfire, but is still vulnerable to artillery shells.

Dwarves

Short, stocky, and bearded, the typical Dwarves of 'fantasy fiction' are among the races seen at the bar in Alnus. The Dwarves are known among the inhabitants as skilled blacksmiths and metalworkers. Some are seen carrying large weapons, suggesting that they are strong and skilled combatants in spite of their short stature. They are frequently utilized as chief engineers for shipbuilding projects by Avion Sea nations.

Pooka

Avi

These winged humanoids are six-limbed, having two wings growing out of their back in addition to 2 arms and 2 legs, similar to depictions of "angels", and have feathers in a variety of colors including white, black and tan. Unlike Sirens, Avi are fully capable of flight. Avi are native to the Avion Sea, and many serve as the 'Guardian Protector' of ocean-going ships. In addition to being a religious role to appease gods of winds and waves, they also serve as the ship's spotter, pilot, weatherman, navigator, and messenger. Examples include Odette Ze Nebula and Mizari.

Sirens

Sirens are humanoids with bird-like feathers from their arms and heads, as well as avian-like feet. While some have arm feathers thick enough to resemble wings, they do not seem to be capable of flight.They have the ability to use powerful wind magic. The most prominent Siren featured in the anime is Myuute Luna Sires, who volunteers as a local police auxiliary, acting as an underling of Rory Mercury and the JSDF MP.

Draconians

A tribe of humanoids with dragon-like features, including wings, scales, and sharpened teeth, have been encountered by the JSDF, the most notable being Giselle. They are known to be capable of communicating with Dragons to a degree, as well as taming them more easily. This is made evident by Giselle's success in taming the cubs of the Flame Dragon.

Faries

Faries are shown to exist in the manga, but not in the LN or anime. These humanoids are small and are capable of flight using insect-like wings. A pacifist species that, due to their small size, handle small jobs such as handing pens to others and providing desk assistances. Groups of fairies can cooperate to handle heavy objects see Fairies at work in Gallery. Although pacifist they have been known to swarm heros, see Tuka being swarmed in Gallery. Fay is the best known.

Aquatic Humanoids

Aqua

Aqua are a species of mermaid native to the Blue and Avion Seas. A painting of one is seen in the Formal Mansion in Italica. Itami meets a few while marooned with Pina during the Gaiden. Aqua are employed by the JMSDF to guide their submarine through complex underwater terrain like shallows or coral forests, or for drudging operations to build out the navy base in Vaasa. Kemmy and Yuri are significant Aqua characters from Gate Season 2.

Trito

A type of aquatic dragonfolk that have small, fine multi-colored scales, a fish-like swimming tail, and two legs. Trito are not that smart, and have not discovered fire on their own. They are easily bought out or swayed by humans or other humanoids.

The JSDF first encounter a group of Trito armed with tridents at the Roma River, who demand restitution for intruding on their territory. A second tribe, the Meggido, are found on Meggido Island in the Avion Sea, and have taken up trade with pirates and merchants.

Galla and Dicle

Described as the underwater equivalent of goblins and orcs, respectively, are about as intelligent, and are incapable of speech. They hide from the Kitashio when it enters their home in the Undersea Coral Passage.

Part-Animals

A number of humanoids exist in the Special Region that seem to possess land-animal characteristics, typically the ears and tails. JSDF personnel find them similar in appearance to "kedamonomimi" anime stock characters.

Warrior Bunnies

Strong, agile, disciplined, and feminine lagomorphic humanoids best known for being fast and fierce warriors and assassins. The best known from the Anime are Tyuule former Queen now slave of Zorzal, and Delilah bar maid and spy in Alnus. In the Manga are the name of two bunnies Delilah escaped with Griine and Parna.

The known named cat-person who has appeared in Gate thus far is Persia, a former maid of the Formal Clan, Meia, Miicul, and Atya from Fatima's Gang. They also have a reputation for being exceptional assassins, with both Persia and Atya showing a familiarity with both combat and toxins, with Atya identifying Indelma from scent alone. Based on remarks made by Meia, cat-people are another oppressed minority in the Empire.

Medusae

Medusae are humanoids with numerous 'snake heads' sprouting from the scalp, as if they are hair as to the like of normal humans. These 'snake heads' possess the ability to feed on the life force of a victim, as well as the ability to read minds. For this reason, they are generally feared and resented by other races and are particularly exterminated in the Empire. Aurea, a maid in the Formal Clan is the most prominent medusa character seen thus far in the series.

Volraden

The Volraden are a tribe of the demi-human Werewolf race with wolf-like canine appearance. They hail from the Mountain of Snow and Winter in the North of the Special Region.They often serve as mercenaries for various countries in the Special Region. Most of them are seen doing their warrior for hire jobs as Military Policemen (MP) or convoy guards in Alnus like Wolf.

Unlike most humanoids, "werewolves" look more like sapient bipedal wolves than humans with animal characteristics and may not be genetically related to humans. They are not seen to transform from human to wolf, and are not bothered by the mere presence of silver, like traditional werewolves of fantasy

Leonoids

Bipedal anthropomorphic lion and tiger-like beings are seen in Alnus and Sadera, including members of the Akusho crime families. Like werewolves/Volralden of the Special Region, Leonoids appear more like animals with an anthropomorphic body structure than humans with some animal characteristics.

Centaurs

Kobolds

A aggressive and salvage race of wolf-like demi-human that bear quite resemblance to the Voldradens. According to Wolf, Kobolds are far inferior than Voldradens in combat.
