Dual-Soul

**Dual-Soul** *(二元的霊,Nigenrei)* is a unique term used when referring to a unique individuals that reside within the world.

## Overview

Dual Souls are known to be souls composed of two identical souls, first appearing sometime during the Incursion. Due to their nature, they are more often stronger then the standard soul and can shake the balance of the world; as a result they were often hunted down for various reasons. After the world was stabilized many of the dual souls were killed and the remaining went into hiding with a negative rumor spread about them with in the Soul Society. However after the Quincy Invasion and one individual having a major contribution in protecting the Soul Society, lead to them being accepted with a false origin of them being circulated around. While the effects of Dual-Souls various between racial groups, one trait exist between them and that is a unique Reiatsu "mark" that is detectable by a shrewd enough observer. They are divined into three different classes.

### Classes

**United**: Know to be the most stable of the three with their "mark" being more difficult to notice. They are result of the two souls perfectly merging together, result in an entirely new soul being born often with a personality born from the original two.

**Petra**: This class is known to be the most common of the classes, and is the result of one soul consuming the other. Similar to the process used by hollows. Unlike hollows, the winning soul will gain the powers and knowledge of the loosing one. Due to their nature they are sometimes referred to as pseudo hollows. Their "marks" are known to be the easier to be detected, but a well trained petra is able to hide it.

**Fractured Soul**: Stated to be the most unstable to the class, with their "mark" being on full display. They are a result of the two souls failing to fuse, resulting in chimera or partial fusion. Uniquely their unstable nature often results in them possessing larger Reiatsu then their other classes. They are known succumb to instantly or enter a berserk state, due to this they are often quickly hunted down and killed or imprisoned.

### Effects on Races

Regardless of the class they fall into, the effects they have on their race are similar.

**Shinigami**: Progressing normally like a standard Shinigmai, they differ mostly when attempting to imprint on a Zanpakutō. They are unable to imprint on a single Zanpakutō and require a second one or a special made one. Upon imprinting on both, each Zanpakutō is known to have its own release command, abilities and spirit. Additionally due to their unique soul they are unable to achieve Bankai, however a new release was developed by [-].

* **Gōdōkai** *(合同解,Union Release)*: Is a release that allows a Dual-Soul to temporally reunite their souls, which in turns merges their two Zanpakutō into one. Said Zanpakutō is then released with a phrase much like that of a standard Shikai. A Gōdōkai is stated to be the true power a Dual-Soul Shinigami possess. The method to obtain a Gōdōkai is stated to be similar to obtaining a bankai.

**Hollow**: A hollow that possess Dual-Soul is known to have an easier time of becoming and retaining the position of dominate soul during their Menos stage and higher. Additionally they are known to quickly develop into Vasto Lorde class hollows.

* **Renacimiento** *(再生刃,* Renashimiento*; Spanish for "*Rebirth*", Japanese for "*Reborn Blade*")*: is a unique transformation and evolution used by hollow dual souls. When use in use or achieved they are know to appear entirely human, possessing no outward hollow features. They known to be more powerful then a stranded vasto lorde but are much rarer.

**Human**: Humans that possess a Dual-Soul are know to be spiritually aware and awaken abilities at a much younger age, at times awaking more then one. This is also the case for Humans that happen to become fullbringers.

**Quincy**: Known to rare among them a quincy that possess a dual souls is known to be capable of awakening two Schrifts.
