Sephira Crystals (霊結晶セフイラ, Sefira?. lit. "Spirit Crystal") are mysterious gems that act as the source of a Spirit's powers and are responsible for turning humans into Spirits. They also have alternate forms called Qlipha Crystals that contain Demon Kings and serve as the power source of the Spirits' Inverse Forms.

Usage

Bonding

In order for a Sephira Crystal to turn a human into a Spirit, they simply need to touch it. The gem is then absorbed into the one who touched it and will turn that person into a Spirit. When Origami was being turned into a Spirit, she described the feeling as "as if a second heart was being created inside her".

Compatibility

Human beings have varying levels of compatibility for becoming a host for the Sephira Crystals, with Phantom stating that Origami was an exceptional user due to wielding her Angel so skillfully.

As seen from Kotori's example, Sephira Crystals can be toxic to the host's body, and can even induce madness. As a result, Mio stated that they need to be further refined by killing the initial host and then transplanting the gem into another host. Doing so, would ensure that the Sephira Crystals will come closer to completion and resolve the negative drawbacks. According to Mio, while the attributes of each Sephira Crystal is pre-determined, the powers that manifest can vary depending on the personality of each host.

After Mio's death, her then lingering Sephira is quickly taken in by Tenka before it could disappear. However, despite being Mio's daughter, Tenka notes that even she was not fully compatible with Mio's powers. Most of the Reiryoku granted is spent preventing the defensive instinct of the Sephira from taking over. To circumvent this, Tenka uses the Sephira's power to create an artificial world where time was compressed to the limit. In doing so, she is able to extend both her remaining lifespan and the amount of time she had as the inheritor of Mio's Sephira.

Extraction

Removal

So far, there have shown to be three ways for a Sephira Crystal can be removed from a Spirits' body. The first method is to kill the Spirit. Second, seal all the Reiryoku in Shido's body and then use a Realizer to remove it from his body in the form of a new Sephira Crystal. Finally, Artemisia has also shown the ability to remove a Qlipha Crystal through unknown means by using her Territory, though Nia was left with a sliver of her Sephira Crystal because Shido partially awakened her from Inversion. Ellen also says that she possesses a similar ability. Mio has also displayed the ability to removal Sephira Crystals from their hosts by using her Angels and Astral Dress as a weapon, although her methods in retriving the Sephira Crystals lead to the death of all the Spirits who were originally human. As a pure Spirit, Tohka having her Sephira Crystal extracted by Mio caused a temporary loss of her physical form.

Destruction

Despite their supernatural existence, Sephira Crystals are not indestructable and can be destroyed. When contemptating what to do with Tenka, Mio remarked that she could simply imbue her hand with Reiryoku to crush the Sephria Crystal into dust. During their battle in outer space, Ellen was worried that the Sephira Crystals may become lost forever if they completely destroyed Fraxinus. Mio's final Angel <Ain> is also capable of completely erasing a Sephira Crystal from her existence. After doing so to Tohka, she laments that this method completely eliminates Tohka's Reiryoku from the world. However, it also prevents Tohka from resurrecting herself like she did beforehand when Mio merely extracted the Sandalphon crystal.

Lastly, due to being created by Mio, the Sephira Crystals are tied to her lifeforce. After Mio's death, the other Spirits' Sephira Crystals all fade away, turning them back into ordinary humans, with the expection of Tohka who disappears along with her crystal.

History

According to Inverse Tohka, the Sephira Crystals first emerged as Qlipha Crystals when the First Spirit decided to divided her power. The Inverse Spirit later speculates that she reversed their properties into Sephira Crystals in order to make them more compatible for human hosts.

When creating the Sephira Crystals, Mio split off and condensed a portion of the Reiryoku. Along with her power, the Sephira Crystal were breathed with a portion of her emotions as well, with the color being determined by which particular feeling was strongest during its creation. If the emotion was wrath, it would be a fierce red. For blue, it was a sorrowful blue. If it was regret, it would be a bottomless black. The more negative the emotion, the stronger the Spirit would become. However, that also increased the toxicity of the Sephira Crystal as well. In order to purify the Sephira Crystal, she would use humans as sacrifices. Each time the Sephira crystal went through a new host, it would become slowly purified as if undergoing a filter treatment. Those that were used as 'filters' lost control of themselves when given a freshly made Sephira, going berserk and attacking everything in sight. This caused Mio to need to repeat this process numerous times, transplanting the Sephira into numerous hosts until it was fully purified.

One day, Mio wondered if it was possible to create a fully purified Sephira from the beginning. To do this, Mio used the strongest emotion that was source of all of her motivation: love. She concentrated her mind and separated the so-called “poison” that could harm humans into a place inside Sephira. However, that produced the unexpected effect of a Sephira gaining its own will. This Sephira would later develop into the second pure Spirit after Mio, growing to eventually become Tohka Yatogami.

Trivia

  • The term Sephira is derived from Sephirot Tree, the tree that the Spirits are based on.
    • Each Crystal's color, like the Spirit's hair color, is based on the color for their Sephira on the Tree of Life.
