Nox

Nox is an Arch Demon that resides within Daidra Senboru's body after ingesting Akuma-Ara's blood and is the main antagonist in Sekainoowari, he possesses the Chikara, Shambles. Nox and Daidra were forced to share a body until Nox broke his will, gaining absolute control of both Daidra and his Chikara. Nox always displays an extreme discontent towards Humans and will rarely ever spare anyone who he engages in combat with.

Low/High Demon Form
Nox assumes the natural look of Daidra even when in control of his body, with his eyes being even redder than his host. Standing roughly six feet and seven inches tall, Nox is eight inches taller than Daidra. In addition to his height, Nox is also incredibly muscular; however, not in a sense that makes his body larger. Nox's muscles are twice as dense as an average Human, making him seem a lot weaker than he is. Nox typically wears ragged trousers with no covering on his upper body, which exposes his black tattoos on his back and arms. Even though Nox is a High Demon, he has no visible horns on his head due to his connection to Daidra's body. When Nox activates his Chikara, he grows three inches taller and his muscles triple in size.

Arch Demon Form
After Nox's Arch Demon evolution, he acquired the kettou jouken, the Sanjigan.

Post-Xuzin War Arc Form
After taking Isui Odaka's Tensougan, Nox formed a fourth eye socket and inserted it there. Over time the Tensougan fell under his control and became the Mugen Tensougan

Personality
Nox is sadistic in nature, having an extreme discontent for all Humans with occasional disregard for all other races besides his own. In Nox's eyes, all other races that are not of Demon origin are inferior to his own and will be treated as such. Besides this, Nox was incredibly loyal to Akuma-Ara up until his loss to Kazega Eijizoyo. Despite his hatred for Humans, Nox holds respect toward Kazega Eijizoyo for his strength and fortitude.

History

 * -|Origin=

Nox was one of the last Humans to live in the Last Epoch before succumbing to old age and dying aboard the TON 618 Patentia. Nox was later reincarnated trillions of years after the Reverse Big Bang as one of the first wandering Low Demons in Shimetsukeru. After being found by Akuma-Ara, Nox's primal mind instinctively attacked him, and his physical body perished as a result. However, instead of his Soul dissipating, it was taken into Akuma-Ara's body.

After the abduction of a renowned doctor, who was also a Holder, named Daidra Senboru, he was brought before Akuma-Ara and forced to ingest his blood to protect his family from being killed. When ingesting Akuma's blood, Daidra's own unique cells rejected it, resulting in the Demon transformation process being botched and leaving Daidra with a split personality with Nox. It was later found that Nox's Soul seeped out through the self-inflicted wound on Akuma-Ara wrist.

After the ordeal surrounding Seiko is resolved. Nox and his two cohorts, Xazal and Mivra, appear nearby while Rhaust is getting some air. In Rhaust's bad physical and mental state, he did not put up much of a fight when being captured by Nox. However, Kazega Eijizoyo senses Nox's demonic energy nearby and checks things out, witnessing Rhaust's capture and attempts to intervene. Nox, with his superior strength, overpowers Kazega and initiates combat with him. The one-sided fight between Nox and Kazega lasts for a while, resulting in Kazega sustaining many injuries and falling unconscious after being ruthlessly beaten by Nox. Nox, after the battle, takes strands of hair from Kazega's head for later study.


 * -|Shimetsukeru Arc=

Before the battle between Kazega and Akuma, Nox combatted Soura Yamanashi. Soura; using his Chikara, Pandora, pinned Nox's limbs one by one with Brimstone, completely subduing him. Nox, because of his ties to Shimetsukeru, is unable to break, let alone damage Brimstone.

After the battle, Nox is broken free by Xazal, being notified that Akuma was defeated by Kazega. Upon hearing this news, Nox lashes out on two Lower Demons, killing them out of rage. Nox quickly grabs Akuma's severed arm before retreating to his hidden study.

As Namix Akiyama dawns the Demon Crown as the Second Demon King, Nox instantly sees an opportunity. Knowing he could easily take the crown from her, Nox challenges Namix and defeats her in combat; ripping the crown from her head and placing it on his own. Namix, after having the crown taken, falls into a coma.

Now wearing the Demon Crown, Nox becomes the Third Demon King and soon realizes its power; the ability to manifest and cull souls from the bodies of Demons. Nox would soon begin experiments to create a vessel to house these souls and use them to wreak havoc in the Doryoku. Not seeing a use for Xazal and Mivra anymore, Nox destroys their bodies and devours their souls; gaining their Chikaras, Fallen and Persona.

Nox would often attempt to infiltrate Persecom and gather information, but could not gather much due to Nala and her Chikara, Oculus.

After the activation of the Vermillion Pact, Nox became disgusted with his new Human appearance and tore off his face, which regrew quickly each time. Nox soon learned how to suppress his Vermillion form and completely rejected it, never changing into his Vermillion form again.

After gaining the power of the Demon Crown, Nox creates the Cauldron to experiment with souls taken from Demons. Using the Demons souls and Akuma's severed arm, Nox creates new cells to form an artificial body to house the soul, which he called a Vessel. His first experiments with such little DNA from the severed arm proved unsuccessful and would result in "incomplete" vessels incapable of speech, seeing, hearing, and sometimes moving.

After multiple failures, Nox trespasses into Kazega's home while he was still in a comatose state in an attempt to take hair strands from his wife, Rena Iris. Rena resisted multiple times despite being effected by Felinitis, causing Nox to injure multiple limbs and knock her unconscious; because of this, she was unable to take her medication for the disease, resulting in her death.

Returning to the Cauldron, Nox infuses Kazega and Rena's strands of hair with Vessel components, creating the first successful Vessel, Karaima Eijizoyo. Nox nurtures Karaima for ten years before sending him to the battlefield in which Kazega and Akala are fighting on to locate and retrieve Kisuragi, a humanoid Voidborn trapped within a mass of amalgamated flesh and Void tendrils. Upon reaching Kisuragi in the center of the mass, he telepathically communicates with Karaima, reminding him of his difficult and childhood which he has mixed feelings. As this happens, Karaima would no longer focus on retrieving Kisuragi, but instead try to save him from the agony that he was currently enduring. Kisuragi tells Karaima of a man who closely resembles him, giving hints that directly correlate to Kazega; who is also connected to Kisuragi at that time. As Kisuragi continues to scream in agony as his uncontrollable amalgam grows, Karaima tears at the tendrils surrounding him while simultaneously being battered by them on all sides. Karaima uses his incomplete Chikara, Prime, to burn away the masses and make more progress. As the void-flesh burns away, it instantly regenerates, leaving Karaima with a sense of helplessness. As Karaima begins to cry, a hand is placed on his warm, sending a bluish energy through his arm and into the void-flesh, disintegrating it instantly. Karaima looks to the man holding his arm, and sees a man that closely resembles him, but with blue hair instead of his red-ish hair. The void tendrils, being flooded with Kazega's energy, all cease moving and wither away. The mass slowly becomes blackened and disintegrates into ash, leaving Kisuragi, Kazega, and Karaima all sitting on the scarred ground. Kazega points out how much Karaima looks like him, placing his hand on Karaima's head and bringing him into an embrace, to which Karaima instinctively hugs him in return in gratitude and relief.

After Karaima's act of betrayal, Nox continues to study the creation of Vessels and attempts creating them from scratch.

After multiple failures, Nox discovers a method of creating Vessels using only the souls of High Demons, creating Itami, Goz, and Selagoth in the process. However, it quickly became apparent that the Vessels were still imperfect and had their lifespans significantly shortened compared to Karaima.
