Choujin

**Choujin** (超人, *Chо̄jin*?, lit. "Superman/Superhuman") are individuals that have been granted superhuman abilities through yet unknown means. The nature of Choujin powers is heavily linked to emotion and desire.

## Description

A Choujin is a person that has superhuman abilities. A Choujin's power and form is greatly influenced by their emotional state and desires, so much so that Yamato Mori has a rule specifically surrounding spontaneous usage of powers influenced by emotional outbursts. It also seems as though the potency of Choujin power is also linked to age, as Chandra talks to himself about his fumes not being as strong ever since he's gotten older.

To become a Choujin, a person must have the aptitude required to become one, which can be obtained through various means such as inheritance, infection or awakening through stress. It is stated that a person with Choujin aptitude has to go through a tremendous amount of stress to activate a so-called "**Chaos** State". When a person returns to normal after their first **Chaos**, they have officially become a Choujin.

Yamato Mori, a organization made by Choujin for Choujin, has a three-tier registration system; unregistered Choujin, Class B Choujin and Class A Choujin. Unregistered Choujin will suffer consequences for using their power, no matter the circumstance. Class B Choujin can use their power to save people, to defend oneself, and for accidental use. Class A Choujin can use their power for research purposes and/or the betterment of society. It is known to take 40 days to obtain a Class B registration. Yamato Mori also has a Keeper program to train Choujin to help people and stop Choujin who would want to use their power to hurt others.

It should be noted that among the "normal" populace, resentment over Choujin exists, as they seem to use freely their powers to benefit themselves instead of society as a whole. Azuma noted that "They get away with doing whatever they want", however, what he meant by that remains unclear. Choujin aren't allowed to play in sports leagues at all because of the unfair advantage. Some Choujin even have bounties on their heads.

**Choujin X** are individuals who seem to appear in every generation. They have a power capable of breaking any balance and depending on their nature they can become a salvation for people or bearers of calamities and destruction. The known ones are Quiem "War Choujin", Sora "Blessed Beast" and Bill Morth "Emperor Immortal".

## Biology

All Choujin possess a type of abnormality, referred to as Super Cells. Super Cells allows them to manipulate Universal Particles, the base particle of everything in the world, and use their superhuman abilities.

## Abilities

Choujin are granted superhuman abilities, ranging from transforming one's body (e.g., into a flexible material, or the form of an animal), to creating substances (e.g., expelling fire from one's fingertips), etc.

Choujin abilities become more powerful the greater the "risk" (リスク, *risuku*?) involved in their usage; most generally, in exchange for the risk of **Chaos** and the loss of self, a Choujin gains a powerful ability.

### Chaos

**Chaos** (混沌 (カオス) , *Kaosu*?), also referred to as **Chaosification** (混沌 (カオス) 化, *Kaosu-ka*?), is a berserker state in which a Choujin's abilities are enhanced exponentially but also take over the individual, causing them to lose control and their sense of self, even permanently. **Chaos** can be a consequence of strong stress or emotions, as that is what is needed to turn a human with aptitude into a Choujin. Yamato Mori allows licenses for registered Choujins for sudden discharges, as their abilities can manifest suddenly without their control sometimes. Some subjects treat this condition as another way to acquire power, voluntarily losing their humanity and even coming to believe themselves gods. There are religious organizations that believe Choujin exist as a means to reach god and that the state of **"Chaos"** is the path to approach the divine and enlightenment.

### Raise

**Raise** (修復 (レイズ)  or 甦生 (レイズ) ／蘇生 (レイズ) , **Reizu**?) is an ability intrinsic to every single Choujin, given that not wanting to die is a human's most basic desire. It fuses "destruction" (破壊, *hakai*?) and "creation" (生成, *seisei*?) to allow a Choujin to revive and recover following the incurrence of mortal injuries, completely regenerating their body. As Choujin abilities are enhanced by taking on risk, **Raise** is so potent a trait precisely because it increases the risk of death. Normally, a strong **Raise** can be activated two or three times a day, but it depends on the energy and willpower of the subject; in general, Choujin are constantly in a slight **Raise** state, meaning they automatically heal, though that can be supressed. The consequence of this power is the gradual loss of humanity with each use, getting closer and closer to death and having to overcome their human limitations to be reborn, their form and mentality becoming more and more similar to their state as a Choujin.

### Ability Classifications

Based on the nature of their powers, Choujin abilities can be distinguished between:

* **Shifter** (変身系, *Henshin-kei*?): based on bodily transformation, such as Beastification. The strength of a Choujin of this type depends largely on their physical prowess prior to their transformation.
* **Creator** (生成系, *Seisei-kei*?): based on creating certain substances, such as smoke or iron.
* **Double** (ダブル, *Daburu*?): a hybrid of Shifter and Creator.

**Beastification Choujin** (獣化の超人, *Jūka no Chōjin*?), or simply **Beast Choujin** (獣の超人, *Kemono no Chōjin*?), are a particular subcategory of Choujin that can undergo so-called Beastification to greatly improve their physical abilities by adopting the physiological traits of animals (acquiring the body parts and thus abilities of certain animals, like running fast, flight, a strong sense of smell, etc.). Such Choujin can also talk to animals, and regarding their ability to transform into beasts, one can distinguish between:

* **Complete Beastification** (完全獣化, *Kanzen Jūka*?): spreading the Beastification over the entire body, drastically increasing the Choujin's overall physical abilities.
* **Partial Beastification** (部分獣化, *Bubun Jūka*?): beastifying individual body parts with perfect control; more difficult to achieve.
