Demon Nexus Nex (born Chae Jae-Hyuk), is a main character of the Cavalier of the Abyss manwha. He has deep affection towards the Demon Clan's Demon Serin, and has had two children, Ninoorut Noah and Siana Nexus, with her. However, he has since imprisoned her and labeled her a traitor for currently unknown reasons. He also has a daughter with Iffrita Noah, Miya. He was the Regis of Chaos until he was dethroned by Caladbolg.
Regis Nex has brown hair and wears royal clothes with a cape. His clothes usually have fur. He can adjust his clothes with magic. When in battle he has his sword Depore and usually takes off his cape.
When Regis Nex was young he would help everyone in need. He was kind and very protective of his comrades, especially Serin. However, As time moved on Nex changed completely and became cruel and merciless towards both allies and enemies alike. It was a result of Serin betraying him and running away from him and taking his first born son. Also, having lost his brother to Caladbolg, causing him to have a experienced great pain.
It is then revealed that his cruelty sprouted after a conversation with Caladbolg. Seeing the demon slaughter his men and innocent civilians horrified him, showing that he does care for his people, and after the talk, he resolved to kill the latter even when goaded at the possibility of his brother regaining control.
With the aspect is that he vehemently denies any relation with the Night Clan. This could be hinted to his reminding of how he became the king, or because of the secret fear he has of being a member of the Night, ie human, due to the knowledge that whatever Caladbolg touches is mutated beyond recognition and losing his purpose in Chaos. Everything except him and his bloodline, due to him being night, human before, making his children human-demon and human-dragon hybrids. It is also stated that he is racked with so much guilt that he can barely sleep and has chronic nightmares all the time.
When it cames to his children, Nex shows his caring side, always treating his daughter Miya as a treasure, and valuing her above all else. However, Nex would treat his son, Ninoorut, as a burden, do to the assumption that Ninoorut was not his son, and was born through an affair Nex's wife, Iffrita, had.
Later it was revealed that he had intended to give Ninuroot the throne all along regardless of blood, but he pushed him away so that he doesn't become him. This shows he has no prejudice for the Prince , but wanted him to grow up as a kinder and better ruler than him.
Long before he became the Regis, Demon Nexus Nex was named Chae Jae-Hyuk and lived with his young brother, Jae-Hoon, in a small one room apartment in the human world. The young Jae-Hyuk spent most of his time traveling between school and multiple part-time jobs, so that he could take care of his sick brother.
During an unfortunate night, while trying to get his sickly brother to the hospital, he is accidentally injured by Demon Serin during a battle, and dies. She brings him back to life as an Undead but because his mere proximity to his ailing brother was slowly killing the young Jae-Hoon he accepts having to go to Chaos with Serin so that he can learn to control his powers and later return to his brothers side. Sadly, his brother is possessed by Caladbolg which results in him cutting all ties with Serin who brought the child over for medical care. After dueling Caladbolg and cutting alliances with Serin and his former school friends he chooses to travel alone with Depore as his sole companion.
At the beginning of the story, Regis Nex is shown traveling with his warriors to a neighboring village in order to destroy a traitor. One of his warriors pleads for Nex not to slaughter the entire village which Nex quickly attacks the man for defying his word. Soon enough, the traitor and anybody deemed a follower was murdered. Nex, then travels to meet with Princess Yuan, the woman engaged to Prince Ninoorut.
When the Princess arrives, Nex can easily detect the hostile energy radiating from Xix, but pretends to not notice it until he is close enough to strike both Xix and Yuan down easily. Xix is shocked by how easily Nex was willing to let the Princess die alongside him and takes the blow meant for both. Xix and Nex quickly duel with the Regis, along with Depore, proving to be the stronger combatant. During the middle of the duel, Nex is surprised to learn that Xix is another undead. But despite his shock he easily rips Xix's heart out and gloats over how an undead can still suffer some forms of pain. He then orders for Xix to be dragged back to the castle as they return for the engagement ceremony.
Upon return, the Regis commands Yuan to meet the Prince. When Ninoorut attempts to show his father respect, the Regis snubs him publicly much to the Prince's humiliation. While the engagement commences, Nex steps out to go shower for the event. While his maids bathe him, Iffrita and Nex discuss about how silly her constant worrying over his well-being since he always returns home fine. A maid discovers that an injury Xix dealt him earlier still hasn't healed and Nex grows irritated and begins stalking off but is stopped by Iffrita, who attempts gaining her husband's attention. He coldly dismisses her and heads off to the Great Betrayer's imprisonment chamber; Demon necromancer Serin.
When Nex sees the catatonic woman he is quick to gloat over how her betrayal led to her current situation. His hostility increases until he savagely bites into her to drain her healing blood. After his wound his healed, he is quick to tell the unresponsive woman that as long as she is alive he will keep her in this state.
After his injury is healed, he returns to the ceremony and watches on in apparent absolute boredom. In the middle of the ceremony, Navarus interrupts the ceremony much to the shock of everyone, but Nex who finds the situation amusing. Navarus claims to have found Nex's true heir and that Prince Ninoorut is a fake, which Iffrita is quick to dismiss as lies, while Nex asks for proof. Before Navarus can introduce the apparent heir, Xix reawakens possessed by the demon he had formed a contract with Skoll.
Skoll possessed Xix quickly strikes down several of the Imperial guard when the Prince steps in to fight, Nex watches with slight interest. While Xix and Ninoorut duel, Depore awakens to warn Nex that another evil has awaken. When Ninoorut is overpowered by Xix, Navarus's claimed true heir, Just, makes his appearance. Just easily overpowers the possessed undead being another one of Osky's evils himself; Ouroboros. Just is about to land the killing blow on Xix when Nex finally steps in to stop him. Nex is suspicious of Just and questions him on being Serin and his child. He is especially interested in whether or not Just knows about the demon stone, Semek, that Serin had wielded. Just claims to be unaware of where the stone is, and Nex does not look appeased by this answer, but nonetheless accepts it as true. While they are discussing Just's legitimacy, a returned normal Xix makes his escape and Nex orders him to be killed upon found.
Nex recognizes Skoll as one of Osky's creations and quickly travels to meet with the creator of evil. His main objective is to find out more information on the demons and if Osky is aware on whether or not Just is his true heir. When he meets with Osky, he quickly loses his temper when Osky taunts Nex about asking his first wife if Just is their son or not. While he doesn't find any information on whether or not Just is truly his heir, he does find some information on Xix's hatred towards him.
After his meeting with Osky, he is informed on Miya's kidnapping by Night Clan members. He travels to Thanatos where she was taken. When he finally arrives, he interuppts a battle between Owen and Seon Yu, his old classmates under Mistress Infinity's. Seon Yu heatedly proclaims Nex as the slaughterer of his people and fiance, to which Nex reveals it was Seon Yu who was the true murderer all along in a state of madness.
Powers & Abilities

- Dark Claw "True Form": Nex uses the Dark Claw to clad himself in a suit of black armor.
A striking technique originally used only by members of the Serpent Clan, it can be used by those who have a body structure similar to serpent, however for those people, overusing the technique comes at a great cost to the user's life span. There are 9 levels in Tae-Gyuk, Regis Nex achieved up to the 8th level, but did not try to reach the final level because of the cost to the user's life span.
A demon stone who is able to transform into different types of weapons. While fighting Caladbolg, Nex draws upon Depore's power in an effort to behead Caladbolg. At the same time, Depore is not indestructible, as seen when Nex's sword cracked after Caladbolg stopped Nex's "Depore Square" attack.
- "Dual Blades" - Depore's form is changed from one large blade to two smaller ones.
- "Down Time Square" - freezes the opponent temporarily. Nex is first seen using this technique on Caladbolg upon their encounter in the Banaan Clan Village.
- "Depore Square" - Depore's density is multiplied, thereby giving much more force and deadliness behind Depore's swing. Also first demonstrated (albeit unsuccessfully) on Caladbolg in the slaughter of the Baanan Clan Village. Misuse of the technique could result in Depore sustaining damage.
- "You're still the same. Your body's being tortured, your mind being eaten by nightmares... It's a punishment worse than death... The traitor of Chaos. The one who betrayed me. Ironic, don't you think? If you aren't alive, I also can't go on living. As long as I need your blood. You are mine. A piece of bone, a drop of blood, all of it. I'll never let it go. Serin." - Regis Nex to Serin, in Chapter 5.
- "Claiming to be my son, and even running away, I can tolerate them. However! Rebelling against me... I will not forgive. Go ahead and vanish along with those you care about." - Regis Nex to Xix, in Chapter 45.
- "If there's a life I can save, if that someone desires my help, I will not stand idle while that life vanishes right in front of me. That's my sense of justice." - Jae-Hyuk, Ch. 34
