Human

**Ranking** | Unknown

**Humans** (人間, *Ningen*) are not deeply concentrated on in *High School DxD*, but they do play an important role in the Devils' ranking system.

## Summary

Largely residing in the human world, humans are the most common species with the largest population in the series. After the Great War had exhausted all Three Factions, the Angels, Fallen Angels, and Devils all had to rely on humans to continue their generation.

The Khaos Brigade's Hero Faction consists of humans that are descendants of heroes, and each has either a Sacred Gear/Longinus, Holy Sword, Demon Sword, or any combination of the three.

There are also the magicians, humans who have learned magic from other religions or factions. It is said that the current magic system used by the humans was developed by Merlin Ambrosius, the legendary wizard from Arthurian legend. Some of these well known magicians are Georg, Le Fay Pendragon, Lavinia Reni and Walburga. The Khaos Brigade have many magicians serving under them, when they attempted to murder the top brass of the Three Factions. It is revealed in Volume 14 that the Khaos Brigade has a magician faction named Nilrem.

There are also humans who have been artificially created for certain purposes. The "Sigurd Institution" were a group who were trying to create the "true descendant of Sigurd" and succeeded with the creation of Siegfried.

## Contracts

Devils need humans to sign contracts with them, which increases their power and standing in the Underworld. However, in order to get the human to sign the contract, the Devil must first fulfill their end of the bargain. These tasks can border on the insane, as Koneko is shown to have cosplayed for some of her contractors, and Issei has been asked to bring a doll to life and make it real by a cross-dressing fan of a series.

A Magician and Devil can also form a pact together, which can be used to make a name for both the Devil and Magician.

## Powers and Abilities

Almost all Humans are recognized as being the weakest among all the races around the world in various regards such as physical abilities; some lacking the same powers as species from the Three Factions. However, some of the humans through training such as Exorcists and famous Heroes have trained themselves to be able to match supernatural beings.

Some humans can attain special powers through strict training or received blessing from powerful beings such as the Gods. One of the examples being the Five Principal Clans, supernatural power users from Shintoism able to manipulate Five Elements (Wood, Fire, Earth, Metal, and Water) their clan represents, undergo spiritual training, as well as their Clan Heirs becoming the hosts of the Five Sacred Beasts. Another example being Vasco Strada, an Exorcist who trained himself to achieve Holy Fist.

Due to the Biblical God, Humans are the only species able to be born with Sacred Gears (even if only half-human), however races such as Fallen Angels from Grigori can steal them from their hosts using a special ritual, resulting in the host's death. Humans who master their Sacred Gears to some extent can defeat High-Class Devils and monsters, on the other hand, those who have Longinus Sacred Gears can potentially fight against God-class beings.

Some rare Humans are born able to wield either Holy or Demonic Swords, which are powerful weapons capable of defeating beings such as High-Ranked Devils and Angels. Based off the swords in question, Humans are also afforded unique abilities such as Caliburn, which granted Arthur spatial manipulation.

Due to their declining numbers, as well as seeking powerful servants, Humans are often sought for reincarnation using Evil Pieces and Brave Saints (it is more centered around Christian believers). Humans attains all the same powers as Devils and Angels, in addition to maintaining their Sacred Gears, as well as still maintaining their traits in wielding Holy and Demonic Swords. Some examples includes, Issei who maintains his Boosted Gear, as well as Xenovia, who maintains her Light Attribute to wield Durandal and Excalibur; both are reincarnated Devils. And Dulio who retained Zenith Tempest after being reincarnated into an Angel.

Humans are capable of also learning to use magic through researching the demonic powers of Devils, using their own rules and formulas to cause and control supernatural phenomena; instead of using their imagination and the power to create such as Devils. Most of the humans who are capable of using this are referred to as Magicians, who often forms their own organizations to research and increase their magical knowledge. Magicians also forms pacts with Devils for protection and knowledge in exchange for a magician's knowledge and techniques. As such, magicians making a pact with famous and powerful Devils is considered a mark of status among them since it will bring them great fortune and success.
