Ninoorut Noah, is a main protagonist of the Cavalier of the Abyss manwha. He is the son of the Regis Nex and Demon Serin, the twin brother of Siana, and is the elder half-brother of princess Miya. He was taken from Demon Serin by Iffrita Noah when he was an infant, and raised as her son (which led Nex to believe that Ninoorut was not actually his son). After fleeing the Blood Ceremony and joining the Clan of the Night, he is branded "The Traitorous Prince," a title many of the Regis's servants and vassals begin referring to him as.


Ninoorut is shown constantly wearing a black uniform similar to clerical wear. During his engagement, he wears dresspants and a plaid dress uniform befitting his royal status. His latest outfit is almost a white uniform similar to the black clerical wear, although the white uniform has an extra layer of cloth hanging around his neck. He always stands in a confident, elegant matter except in the presence of Nex. Ninoorut has light blue hair, which is sometimes portrayed as white. Ninoorut shares very similar features to his mother's cousin, Mikhail. His eyes are violet which are similar to his mother, Iffrita.


When first introduced, Ninoorut is shown as being calm and well-collected. While he generally displays these attributes of being a suave member of a powerful monarchy; truthfully he is plagued by several self-doubts about his identity. One of his negative traits is being impatient, when someone says something offensive towards him he is quick to lash out without regarding the situation. While he does display the facade of being happy, his doubts of being the Regis's son, after rumors begin circling throughout the kingdoms, continuously haunt the young man. Ninoorut wishes for Nex to give him a father's acceptance and is hurt by Nex's lack of acknowledgement. He begins falling apart after Just reveals an imprisoned Serin and asks if Ninoorut is really the Regis's son since Iffrita was rumored to already have been carrying Ninoorut before claiming Nex was the father.

Ninoorut begins to grow more confidence in himself after aligning himself with Night Clan member, Siana. While he is still distressed over his traitious status he becomes more relaxed in the Night Clan's company and openly shows his first genuine signs of happiness while spending time with Siana and Caladborg. Ninoorut's longing for some substance of a family was answered through their appearance; now he openly defies the Regis (the knowledge does sadden him) and will do anything possible to keep both his mother and little sister, along with Caladborg and Siana, safe from Nex.

After Ninurta loses his mind, he becomes quite childlike and innocent, becoming fascinated with even the most simplest things, such as playing with Serin's hair. At the same time, despite losing his mind, he becomes quite sensitive to people's emotions as he was able to accurately detect that Serin's grief and anguish over betraying Nex despite her attempts to deny it.



Ninoorut opens Serin's seal

Ninoorut is first shown stopping royal guards from entering Serin's, a.k.a. The Great Betrayer, chamber where Nex has her imprisoned. Curiousity gets the best of him and he manages to release some of the seals Nex placed to keep intruders from entering the chamber. He gets a small glimpse at Serin and questions what crime was so great that she had to endure such imprisonment.[1]

He is shown at the engagement ceremony where he meets Yuan, his fiance the princess from the Serpent Kingdom. Ninoorut acts cordial to her and appears happy in their ceremony until Yuan mentions how he is well-known amongst the soldiers for his strengths. Her response makes him gloomy and he glances towards Nex, his father, and responds that not everybody would agree.[2]

Ninoorut battles Xix

The ceremony is interuppted by Xix, who is possessed by Skoll, and he goes on a rampage and starts attacking the royal guards. Ninoorut steps in to duel and though he is strong he is no match for the demon Skoll. He is heavily damaged and almost loses to Xix until Navarus arrives. Navarus interuppts the duel claiming to Nex he has found the true heir, Just, unlike the fake heir Ninoorut. This response causes doubt to build in Ninoorut who begins questioning his heritage.[3]

Ninoorut pleads Yuan to save Miya

After Xix flees from the castle, Ninoorut is taken to his bed chambers to seek medical attention. After learning of his little sister Miya's kidnapping he attempts to go rescue her despite his heavy injuries. Yuan stops him and he pleads with her to save Miya since his parents pay little attention to her.[4] Ninoorut returns to his bed to rest when Just stops by to pay him a visit. Just begins to antagonize Ninoorut on his true heritage which aggravates the crown prince. Ninoorut is suspicious of Just, but harbors a deep torment on whether Just is really Nex's true heir. Finally Ninoorut has enough of Just's tormenting and storms off. Just infuriates Ninoorut to the point where the prince tries to land a punch on Just who manages to ward off his strike. Just asks Ninoorut if he would like to learn more about Just's mother, which Ninoorut hesitantely agrees to.

Just easily opens up Serin's chamber and proclaims to Ninoorut that this woman is the only woman who Regis Nex truly loves. Just goes on to explain how strange it was that despite Serin's betrayal all Nex did was imprison her instead of murdering her. Just wonders why Nex would do such a thing and asks whether it was because Nex either could not execute Serin or he wanted her to suffer. Just then brings up how Iffrita appears before Nex already pregnant and says he is the father. Ninoorut is troubled on the knowledge Nex accepted Iffrita's claim without any proof that the baby was truly his son. After Just's story, Ninoorut accidentally overhears a conversation where Iffrita discusses with her father Jihaad on how much misfortunate would come their way if Ninoorut is not the son.

The Royal Seal

Ninoorut travels down to the royal seal where he tries to see if his blood will truly open the seal, which can only be accomplished by those of royal blood. However, he stops himself before the blood can land on the seal as he is afraid of the truth. Osky stumbles upon Ninoorut in the act and tries to lie his way out of causing trouble which Ninoorut already tosses aside the crow's story seeing as how he can sense everything is a lie.

Xix is brought back to the castle and Ninoorut walks in on the group discussing how Xix maybe related to the Regis seeing as how his blood opened Caladborg's Seal when he was accidently strunk down by Nex while protecting Miya. Ninoorut demands an explanation which Xix claims he refuses this outcome because he has no wish to be related to someone who massacred his village.

Powers & Abilities

As the son of Demon Serin and Regis Nex, Ninuoorut Noah possesses tremendous potential and magic capacities. Once the Noah horns were removed from him, the amount of magic he possessed was enough to freeze the entire Royal Castle with various character such as Xix, Yuan, and even Osky left wondering who could possess so much magic.

  • Ice Dragon - Great Red Lotus Flower: This attack sends a blizzard that freezes anybody within a few feet of Ninoorut. All surrounding territory is covered in ice and the enemies are frozen solid (even the enemies' blood droplets froze instantly).
  • Arch Shield: A very powerful barrier that useful in blocking enemy attacks. Almost strong enough to stop a Skoll-possessed Xix's attack.
  • Blizzard Spear: A magic attack that creates five spears which fly towords the target.
  • Frost Sword: A magic ice sword, generated by Ninoorut through magic.
  • Frost Aura: A concentrated ice attack that can completely freeze its targets (Regis Nex is the only one who has been seen to be able to break free from the attack).
  • Undead Abilities: As an Undead, he has increased strength, speed, endurance, accelerated healing, can siphon the life-force of people around him to accelerate his healing.
  • Arc Shield:


Regis Nex

The actual biological father of Ninoorut and his twin sister, Siana. Due to Iffrita's poor attempts to manipulate Nex to gain his favor, the Regis was under the assumption Ninoorut was not his biological child and treated him coldly. Despite enduring years of Nex's aloof manner in regards to his existence, Ninoorut loved his father and wanted to gain his approval as his son. As rumors of his illegitimacy rise, the further Ninoorut sinks into self-doubt and questions whether he is the son of Nex. The prince is a formidable fighter but his strength wanes as his doubts increase, his one major weakness being constantly seeking Nex's approval. After witnessing Iffrita sleep with her cousin, Mikhail, due to Caladborg's relic, Ninoorut flees the blood ceremony not knowing he would pass the blood test due to the misconception he is Mikhail's son. After fleeing the ceremony, Ninoorut is captured by Siana, a Night Clan member and soldier of Nex's greatest enemy. Without thinking things through, Nex is so enraged he orders his guards to either catch or kill Ninoorut and doesn't hesitate attacking the dragon carrying Siana and Ninoorut as they flee. The guards finally find the teenagers and taunt Ninoorut about Nex's orders, causing Ninoorut to lash out and kill the entire platoon. Realizing his father will never approve of him and having nowhere else to go he joins the Night Clan for the rest of the manwha and abandons his title as prince.

Upon meeting Caladborg, leader of the Night Clan and still using Jae-Hoon's body as a host, the former prince often makes comparisons between Caladborg's kindness towards him in comparison to Nex's coldness. Ninoorut does not realize Caladborg is manipulating him and takes advantage of the teen's doubts since he knows Ninoorut's true identity. In Chapter 102, it is revealed that a younger Nex had met with Heklaroth, a prophet of the Vision Clan before Ninoorut's conception, to ask about prophesies. The Vision Clan's prophesied Nex would only have one son that would be born between Regis Nex and Demon Serin. This meant that it would be impossible for any children produced between Nex and Iffrita to be male, leading Nex to believe that Ninoorut (believed to be Iffrita's son) was the product of an affair Iffrita had with her cousin Mikhail, which caused Nex to treat Ninoorut coldly.

Several chapters later, Ninoorut is distraught over being unable to save Iffrita and chooses to rip his horns off in an act of defiance and anguish. Nex warns Ninoorut ripping off his horns would result in his death but the prince is too consumed with grief to care. The king is shellshocked over the former prince's suicide and memories of Ninoorut trying to get his attention over the years send Nex into hysteria and claim Ninoorut's death is entirely on him. Regis Nex and the rest of the parties are surprised to find Ninoorut healing himself as Depore announces the teen is an undead. She further adds that his powers are due to abilities passed down through his bloodline and not given from an outside source. Night Clan member Seon Yu rubs it in Nex's face that the king is ignorant since he wasn't aware that undeads are capable of adapting powers and traits from other clans. Nex and everyone come to the realization Ninoorut is actually his child and the prohesy is true. Siana jumps in front of Ninoorut at that moment to protect her brother and demands to know why Nex has abused the boy for the entirety of his life and abandoned them. The king believes Siana is lying and demands she moves away from Ninoorut but the younger male lashes out and informs Nex not to hurt her. All the revelations about his mistreatment of his actual son make Nex cry out with anguish and during his breakdown Serin is finally awoken from her slumber. Caladborg arrives on the battlefield and takes advantage of Nex's disarrayed state causing Serin to intervene.

Nex collapses from his wounds and is taken to Osky's place to recuperate. The Crow King, per Nex's demands, reveals what happened that caused Serin's betrayal. Nex watches as Iffrita manipulates his younger self into believing Serin had betrayed. He wasn't aware that Serin was pregnant with his children as she is forced to flee before finally seeking shelter from Iffirta, not knowing the woman despises her and wants her dead. Iffrita had tricked Nex into sleeping with her after taking on Serin's form earlier and planned to use the child she was carrying, that was Mikhail's, to make Nex believe it was his. She was about to kill Serin when she suffered a miscarriage. The death of her baby makes Iffrita's madness turn more despicable. She waits until Serin has given birth to Ninoorut- true name being Xix- to steal him away and drug her. She allows thugs to enter the birthing room and give them permission to kill the demon princess. Iffrita takes the baby Ninoorut and implants the horns from her deceased baby onto him to trick others into believing she gave birth to him knowing undeads are able to take on others' abilities. Nex watches Iffrita present Ninoorut to him and a fleeing Serin giving birth to Siana right before she is captured days later.

The manwha ends with an amnesiac Ninoorut standing behind Caladborg next to his mother as Just proclaims he will be the new Regis to the Abyss population. Nex vows to save Serin and his children from them.

Demon Serin

Ninoorut finds the "Great Betrayer" fascinating and often questions what treasonous act she pulled on the Regis to earn her imprisonment. At the beginning of the story Ninoorut warns two guards not to tamper with Nex's seals on her chamber or else they would face his wrath. After they flee, and despite his prior warnings, he still takes the opportunity to release some of her seals to get a glimpse of her as ponders her identity. Time passes, and his next interaction with the Demon Clan princess is not a happy one. With his dread over the upcoming blood ceremony to prove who was the true heir, Just takes advantage of his internal turmoil to taunt him about Serin being the only woman Nex ever loved and Iffrita meant nothing to him. To add further salt to the wound, Just implies those sentiments are extended to Ninoorut, also.

Ninoorut eventually joins side with the Night Clan and is sent on a mission to save Siana. During his travel through dimensions, he encounters a hologram of Serin set up to prevent Night Clan members from traveling between Earth and the Abyss. The hologram stops her asault only after drawing his blood and recognizing him as having blood of the Night Clan. Nioorut appears confused by this revelation and her reasoning for allowing him to pass since he should be considered an enemy.

Several chapters after Siana captures him and he chooses to abandon his title, he only returns to the kingdom after hearing rumors that Iffrita was to be executed. Ninoorut is unable to save her and in his despair chooses to rip off his horns. A desperate Nex warns the teenager that ripping off his horns would result in his death but the prince is too consumed with grief to care and goes through with the removal in a suicide attempt. Just as everyone is overcoming their shock of his passing, he begins to revive himself as his undead abilities awaken. Everyone is dumbfounded and Nex demands to know how this is possible. Depore reveals that the prince's powers are his own through his bloodline and were not provided by an outside entity. Suddenly, the night clan member, Seon Yu, further adds that Nex was not aware that undeads have the ability to adapt powers and techniques of other clans. With all these revelations, the parties discover former prince Ninoorut is actually "Xix," the name Serin and Nex chose for their son, and the one prophesied by Hekaroth to be the child born between them. Upon learning of Ninoorut being his biological son, Serin is finally awoken from her comatose state after being awoken by Nex's cries of despair for his mistreatment of Ninoorut for the past eighteen years. A battle commences between Serin and Caladborg after Nex suffers injuries, Serin is forced to join forces with Caladborg after he manipulates Siana into returning with him to the Night Clan. He brings Ninoorut along per an unknowing Siana's request. Ninoorut has regressed to a childlike state after his revival and appears to have no memories of his former life. Despite his amnesia, Ninoorut is drawn to his biological mother and while she is trying to stay aloof to protect her children from Caladborg's machinations she is unable to ignore her children. Caladborg even remarks the childlike Ninoorut appears happy to just be in her presence.

While Siana is the twin that looks the most similar to Serin, Ninoorut shares more characteristics with his biological mother in terms of personality. They both attempt to appear detached when it comes to interactions but can become extremely emotional when something unsettles them. Often they are the more reserved members in their respective parties and only speak when something important needs to be discussed. Also, they are more sullen than Siana and Jae-Hyuk (before his transformation into Regis Nex). They also shared the desire to be recognized by their fathers and seen as individuals rather than simply being heirs. Even though he had no recollection of Serin as a newborn, Ninoorut was the twin who had more interactions with her growing up and often questioned her identity.


Ninoorut's younger half-sister, Miya may be one of the few people that Ninoorut cares for without doubt. After Miya was kidnapped by the Clan of the Night, Yuan had to physically restrain the injured Ninoorut to keep him from pursuing them, and could only keep him from chasing after them by promising to save Miya herself.

Miya loves her brother and is saddened by his self-doubts, wishing that he would place more worth in himself. Despite their parents differing views of Ninoorut abandoning his title as prince Miya just wants her brother to return home safely. When the siblings reunite in the Snake Kingdom Ninoorut comforts a crying Miya and tells her that he still loves her.

Iffrita Noah

Second wife of Regis Nex, supposed mother of Ninoorut, and former Empress of the Abyss. For the majority of his life, Ninoorut was under the assumption Iffrita was his mother and loved her quite dearly. It isn't revealed until much later that Iffrita actually stole a newborn Ninoorut from his biological mother, Serin, to present to the Regis claiming the newborn was their son after tricking Nex into having sex with her, knowing any blood ceremonies would verify her lies. Despite her manipulative nature, Iffrita did come to genuinely love Ninoorut as her son and doted on him whenever Nex showed disregard to his existence. However, his opinion of her began to sour as rumors of him being illegitimate rose and he questioned whether she truly cared for him since she was fixated on remaining Empress and desperately vying for Nex's attention. His doubts about being Nex's son increased when he saw a memory of Iffrita sleeping with her cousin while claiming her first child would be his. His feelings of tenderness continue to wave as the story progresses and she begins to act cruelly to Miya and him.

After fleeing from the kingdom and joining the Night Clan he learns from Caladborg of Iffrita's incarceration and Nex sentencing Iffrita to death. Despite his confusion towards his heritage and despair over losing his identity Ninoorut still loves his mother and is quick to plan a way to rescue her. Even with Caladborg and Siana reminding him that his goal is a suicidal one at best he is still determined to free Iffrita from Nex's imprisonment. When Iffrita is killed by Nex after becoming contaminated by Caladborg, Ninoorut is so grieved he attempts suicide. The prince cries over her decapitated head and demands an explanation from Regis Nex on why he hated the two of them so passionately. The only reason Ninoorut survived ripping off his horns is that he was actually an undead. Ironically it was Iffrtia's actions which caused most of the grief throughout his entire life. Her actions of stealing him away from his real mother Serin made Nex believe Ninoorut was not his son and caused most of the events transpire that led to Ninoorut's attempted suicide.


Do you hold me dearly as well?

Siana, to Ninoorut Noah

A traumatized Ninoorut first meets the Night Clan's princess after fleeing the Blood Ceremony test. After Just's manipulation Ninoorut is led to believe he is not the Regis's son and will be murdered instantly when his blood is not accepted by the Seal. Before he is given the chance to see if he possesses royal blood he runs into Siana sneaking into the castle. The Night Clan member instantly knocks him out and proceeds to kidnap him. As she takes him away from the castle she manages to destroy the barrier protecting the castle allowing intruders from the Night Clan easier access in the future.

Siana's dragon is hit by a fatal blow from Nex causing the teenagers to be knocked out in a forest near the castle. Ninoorut is the first to awaken and proceeds to internally debate with himself whether or not he should kill the girl. Once again, the decision is made for him, when Siana comes to and begins laughing at his intense expression. Knocking him off her, she tells Ninoorut he will not kill her since he lacks a killing desire. She then goes to her dragon and uses her necromancy powers to allow the dragon to die in peace. Ninoorut is automatically intrigued by the girl's powers since he had never seen this style of magic before. Siana comes back to Ninoorut and starts to taunt him over his crumbling relationship with his father. Ninoorut starts to use his powers on her when Nex's assassins appear telling the prince he is to be brought back dead or alive and Nex's orders claim it doesn't matter which. An outraged Ninoorut uses a one hit killing blast that instantly kills the assassins before collapsing into a moment of devastation. Siana finds the situation hilarious and starts to pester Ninoorut over his swift ability to kill the men when she notices he is shaking. She asks him if he's crying and the prince is quick to brush her off when he is surprised to find her hugging him. The necromancer decides the prince needs comforting and begins to calm him down, Ninoorut, despite his pride as a prince, appreciates her kind gesture and accepts her comfort. After crying his frustrations out he accepts Siana's offer to become a member of the Night Clan.

After getting acquainted with members of the Night Clan Ninoorut slowly begins to open up to the carefree Siana. Her freedom and thrive to live are the polar opposite traits of the refined, reserved Ninoorut. The more time they spent together the more relaxed Ninoorut becomes. For awhile it is uncertain as to what Ninoorut's feelings towards the Night Clan member are until Chapter 93 where he grows fluster as he realizes it isn't comarderie he feels towards Siana but attraction.

Ironically it was Siana's actions that made him a traitor to Chaos and its residents as her actions caused him to skip the test despite his attempts to return, cross over to the Night, help break the barrier that separated both worlds which led to him being deceived by Caladbolg and his subordinates.


  • "Otherwise, the only thing that's true about me...the part of me that admires father and wants to be acknowledged by him, would become a lie." Ninoorut's thoughts, Chapter 49.
  • "This gentle hand on my head. Tells me that I can no longer go back. But...that's its still okay." Ninoorut on Siana, Chapter 50.
  • "I'm going to Merkava. To save my mother. And to cut ties with my father once and for all." Ninoorut to Siana, Chapter 83.
