Kyle Marlon

"...Don't tease me."

- Kyle Marlon

Kyle Marlon was the King of the Kingdom of Marlon and the son of Queen Dowager Prim. After falling in love with Michaela and rejecting his betrothed, Princess Riliane, Kyle unwittingly sparked the Green War. Having lost his beloved to Riliane, Kyle secretly supported the Lucifenian Resistance, annexing Lucifenia as a Marlon territory in the wake of its revolution. While possessed by the Demon of Pride, Kyle threatened to expand an imperialist Marlon regime across all of Evillious.

Early Life
"Under the manipulation of my mother, I quit painting. She hired art dealers and critics to demean my morale and make me leave the world of painting. Since then, I have never painted again."

- Kyle regarding his childhood

Kyle was born in EC 474 within the Marlon Royal Family. Although the rightful heir to the Kingdom of Marlon's crown, he was never interested in being King. Instead, he wished to be a painter, and used the second floor of the royal palace as his studio. At some point, Kyle encountered his mother Prim's close friend Abyss I.R. and, unnerved by her cruelty, avoided her. In EC 484, Kyle met Mikina Sfarz at one of the royal banquets and saw her scream and faint at the sight of a cat.

Showing the talent required, the fourteen-year old Kyle moved into the city with his relatives in EC 488 and progressed quickly under the guidance of Margaret, his art teacher. Struck by Margaret's intelligent demeanor and kindness, Kyle developed a crush on her. That same year, his mother brought a young girl to the palace, told it was a relative of his. Despite her quiet demeanor, Kyle played with the child and eventually had her pose for a new portrait. Sometime after, the girl left without saying goodbye and Kyle was forced to finish have the painting from his imagination.

Once he finished the painting of the blonde girl, it recieved the most praise from his art tutor. At some point, Kyle promised to marry the green-haired woman when he grew up, though soon after discovering she was already marrying someone else. After Margaret's apparent suicide via poison while imprisoned in EC 489, Kyle grew suspicious of the circumstances; hearing that Keel Freesis would do anything if you paid him, the Prince hired the apprentice investigate her death. Soon after, Keel relayed to Kyle how his mother handed the poison off to a guard who gave it to Margaret.

Afterwards, the Marlon prince became fully devoted to becoming an artist, willing to even leave the royal family and meet up with Keel to begin his art career. However, multiple art critics and dealers, including the famed Nikolay Tolle, came by and criticized Kyle's work and, over time, demoralized him from his ideal. Completely broken, the Prince abandoned his dream and burned his collection of paintings in EC 490, save for the portrait his teacher loved so much; around this time, Kyle received a hand mirror from his mother and kept it because it helped alleviate his confusion. Sometime later, Keel bought the painting, saying the prince could buy it back when he felt better, although the price would be doubled.

In EC 494, Kyle was crowned king after his father's death and the political turmoil that followed. He later became acquainted with his betrothed, Princess Riliane of the Kingdom of Lucifenia, and the two would become very close. Later on, Kyle gave her a shell necklace as part of their courtship. At some point, he learned that his mother had bribed the artists and dealers to belittle him. As the years progressed, Kyle overheard numerous titles given to him in regards to being his mother's puppet and his apparent incompetence. Sometime later, the King met and collaborated with Leonhart Avadonia in secret.

Green Romance
"…Up til now, I've still had to give up the idea of leaving my position, mixing with the civilians and live a simple life surrounded by my beloved wife and children" "Does Kyle, his Highness, love me?" "... I see you’re very straight forward."

- Michaela and Kyle

In December of EC 499, Kyle attended one of Keel's banquets at his mansion in Elphegort, he left unsatisfied by the entertainment at the merchant's dinner party. Kyle later attended Riliane's fourteenth birthday party, greeting the Princess at her throne and walking with her among the crowd for a time.

The following month, he attended another banquet at Keel's mansion and watched his new servant, Michaela, come upon stage. Upon seeing her, Kyle was shocked and nearly mistook her for Margaret. Although certain the look-a-like wasn't the same person, he was instantly enamored with her and was even more impressed by her beautiful singing.

Twenty minutes later, the king congratulated Keel for his success after the performance and praised Michaela's voice. Keel introduced the servant girl to the king, mentioning he was a playboy. In reaction to the comment, he nearly cursed but recomposed himself and apologized for his rudeness. Seeing Michaela's nervous demeanor at his position, he told her he intended to remain incognito and that he was fine with her treating him casually like Keel did. Michaela obeyed and Kyle told her they were speaking too casually, prompting her to respond how he truly was a playboy. The embarrassed Kyle choked up when trying to respond.

After one of Michaela's performances sometime later, he knocked on the door to Keel's living room and entered after no one responded; the king saw Michaela gawking at his portrait of Ney and trying to read the signature. Kyle approached her and told her it was his penname: Kachess Crim. Kyle explained to the surprised Michaela his failed art career caused by his mother.

When she asked if he hated being king, he told her he was proud of the responsibility but that his mother remained unsatisfied, despite following the road she paved for him. Staring at her, he spoke of how he still wished he could escape and live among the common folk with a family, provoking the servant to ask if he was in love with her. The king then confessed how he loved her since their first meeting but she turned him down, saying she didn't know how to love a man.

Angered, Kyle tried to explain love to Michaela, and asked if there was anyone she wanted to protect and cared for. When she responded she felt that way about a woman, he was embarrassed but said it was possible if it was true love. He gave her a shell necklace to represent his pure love for her and jokingly threatened that she was refusing the Marlon King's gift.He then blushed and Michaela berated him for abusing his power; Kyle apologized and said he would like them to start out as friends. With a mischievous smile, Kyle heard Michaela agree to the offer and told her being friends with Marlon's king was incredible, much to her ire. He told her he was kidding and retired to the dining room.

Passion of Blue
"Michaela, if I said I intended to disobey my mother, give up my throne and run away... would you go with me?"

- Kyle to his beloved

After hearing of Leonhart's death, Kyle joined in mourning at the warrior's funeral, departing after his burial. Afterward, the Marlon king met with Keel and King Sohni Elphen at the merchant's mansion to discuss Elphegort's poor harvest and Lucifenia's problems. He asked Keel to send aid to Lucifenia to solve their food shortage and sent his own aid from Marlon to assist with the situation as a gesture of good faith to Riliane.

During his visit, he would see Michaela almost daily and they would talk and have fun, with Kyle occasionally buying the servant girl a gift. The day after his meeting with Keel and Elphegort's king, the merchant showed Kyle a unique piece of his collection and the King came in contact with the Venom Sword, feeling a twisting yet comforting feeling as he was unknowingly possessed by the Demon of Lust. The merchant asked if his friend was interested in purchasing the weapon but the blue-haired monarch refused, feeling he would be unable to handle its power.

Afterward, he went to see Michaela and, suddenly filled with an intense and uncontrollable lust for her, cheerfully asked if she would rather go outside rather than do the laundry. Hearing no response, he told her was leaving for Marlon soon and came by to say hello and farewell to Keel but that the merchant was busy. Knowing the captain was waiting, he asked if she would send his regards to Keel instead.

Michaela vehemently told him to ask the butler Bruno instead and the king realized her anger, interpreting it as loneliness at his departure and believing Michaela had finally fallen for him. She rejected the notion and seething, told him she knew he was engaged. Kyle brushed it off and told her Riliane was like his sister, not his lover and said he felt happy she seemed jealous.

Michaela angrily replied she was angry because he was deceiving her before she calmed down and lead him to the door. On their way, he sighed before finally ordering her to turn around. Once she complied, the blue-haired king explained that he did not want to marry Riliane and that the betrothal was decided by their mothers. Michaela asked if he hated the princess and he said that wasn't the case, saying he knew she was not a bad girl and he explained he liked her as a sister, rather than love her as his betrothed. Michaela told him he couldn't defy his mother and Kyle agreed, but hesitated in thought.

He was shocked when the servant rejected him and told him his affair would cause problems with the other countries if it went on. Saddened, he understood what she said and agreed to not cause any harm. The two headed for the door in silence and bid each other farewell as they approached the mansion's main gate. Heading for his entourage, Kyle suddenly ran back to Michaela and embraced her, asking if she would join him if he disobeyed his mother, gave up the throne, and ran away. He released her and told the shocked servant to forget about what he said before departing back to Marlon.

Green Hunting
"I can’t believe he would do such a thing. He would rebel against his mother for such trivial matters. For him to go against his mother’s will of getting engaged to Lucifenia’s Princess... He is such a spoiled brat! He didn’t even consider the consequences of his actions to those around him."

- Keel ranting about Kyle's actions

A few weeks later, Kyle gave a letter to Prime Minister Minis Stoup of Lucifenia to give to Riliane, explaining to the minister that he was withdrawing his engagement to the princess. After telling his mother, the Queen Dowager told Minis she would respect Kyle's decision. With the letter explaining his situation sent with Minis back to Riliane, Kyle prepared to leave for Elphegort but was imprisoned by Prim and kept under house arrest. He was later freed and received a letter from Keel explaining the situation. Knowing Michaela's location, Kyle left Marlon with the intention of rescuing her from Riliane's genocide of the green-haired populace in Elphegort known as the Green Hunting.

About a week later, he arrived and found the one he loved dead inside the well. He hugged her corpse and cried when the former Lucifenian court mage, Elluka Clockworker, and her apprentice, Gumillia, arrived. In his frustration, he kicked and punched violently as the duo extracted Michaela's corpse and soon after departed with the shell necklace he gave her in hand. Donning a mask, Kyle went to the headquarters of the Lucifenian Resistance within the Forest of Bewilderment and told them he could help. He joined the resistance led by Germaine Avadonia, daughter of Leonhart.

Preparation for Insurrection
"We built-up a large amount of people; Not just from Lucifenia but also from Elphegort. And... soldiers from the masked man."

- Minage speaking of Kyle's support

Kyle assisted the resistance and supplied them with his soldiers to bolster their army. During their last meeting in the Resistance's base in the forest, the disguised king's loyalty was questioned by York, a resistance leader. In response to being mistrusted for his mask and the elite weaponry of his soldiers, Kyle responded that there should be no issue since they shared the same goal of overthrowing Riliane's regime. York did not believe him and the masked king insulted him in turn before another resistance leader, Sekka, quieted both of them.

Germaine approached Kyle and touched his mask, noting how poorly it fit upon his face. Astonished, Kyle asked if she had discovered his identity and she responded probably before explaining that his reasons were irrelevant so long as he helped them. When asked what his name was, the disguised king told them to call him "Kachess" and they continued the meeting. When the blacksmith arrived with supplies for the revolutionaries, Kachess sighed and watched as Germaine received her father's reprocessed armor.

Lucifenian Revolution
"We were lucky Marlon did not send any reinforcements." "... You guys are really bad."

- Germaine teasing the masked Kyle

Once the Lucifenian Revolution began, the disguised Kyle and his masked soldiers assisted the Resistance and Elphegort armies and helped score successive victories against the Lucifenian army. On the second week of the Revolution, Kyle's forces staged a night raid on the recalled forces from Retasan Fortress and the Babul Desert region during their return trip, decimating them. Afterward, Kachess led the forces at Rolled to combat the Venom Mercenary Group's forces.

With his own soldiers led by Mark, another revolutionary leader, Kachess combated the mercenaries. The battle continued into the following week and the masked swordsman engaged their commander, Gast Venom, in battle. Kachess was wounded during the fight in his left wrist and was about to be finished off by the "Demon of Asmodean" when Mark intervened and blocked Gast's killing blow. Shortly afterward, Mark was slain but the duel injured Gast and forced him and his mercenaries to flee.

Kachess continued the push with the revolutionary army towards the kingdom's capital. During the assault of the Lucifenian palace's main gate, Kachess, beside Germaine, proclaimed their victory. The red-armored swordsman agreed but mentioned they needed to hurry before the palace's reinforcements returned from Elphegort and noted their serendipity with Marlon not sending any reinforcements to defend Lucifenia. Hearing her deliberate tone, Kyle told her that she was terrible before holding his injured wrist.

Germaine asked if he was alright and he replied he was still able to fight but that Gast and his mercenaries were tough opponents. He lowered his head and apologized for Mark's death during the battle and told Germaine how Mark was the reason the masked warrior was alive. Kachess warned her to beware of engaging Gast in combat, despite the injuries they inflicted him.

Once the main gate was opened and the Heavenly Yard was invaded, Kachess and his forces assailed the courtyard but were held back by Mariam Futapie and her cadre of warrior maids. He yelled at Germaine to ignore Mariam and leave her to Chartette Langley, who distracted the Head of Maids, allowing Kyle's forces to break the enemy lines and assault the palace with Kyle leading the assault.

Kachess and Germaine then divided their forces with Kyle's half finding Prime Minister Minis as he attempted to escape. Kyle tried to arrest the absconding minister but Minis resisted and was killed as a result. He sent a messenger to report his actions to Germaine and the palace was searched before Princess Riliane was found and captured, finishing the revolution.

Sometime later, Kyle visited the imprisoned princess and realized she was not Riliane but her servant, Allen Avadonia, instead. The servant confessed to being Michaela's murderer and Kyle, furious, unleashed his wrath and punched the false princess in the face repeatedly. Once he was finished abusing the prisoner, Kyle told Allen he would execute the boy in place of Riliane, considering the political ramifications if the princess was not believed captured and killed.

Marlon Reforms
"The Kingdom of Lucifenia will now be under Marlon’s rule."

- Kyle to the peace assembly

Soon after the revolution ended, Kyle received a letter from his mother demanding that Lucifenia come under Marlon's jurisdiction. Wishing to prove his competence and finally be rid of ridicule, the ambitious king planned to take full control over Lucifenia and eventually conquer all of Evillious under Marlon's banner, making it the largest and strongest nation in history.

A few days after the Lucifenian Revolution ended, Kyle attended the peace meeting in the Hall of Sounds along with Keel, King Sohni Elphen, Germaine, and the other revolutionary leaders. Once everyone arrived, he was told by Germaine to start the meeting, called by his title of the King of Marlon. Removing his mask, he revealed his identity and congratulated the revolutionary army for giving them their victory after greeting the members present.

Germaine sarcastically asked why he no longer wore his mask, Kyle replying that there was no longer any need; he was prepared to lose the throne as a result of his actions but his mother simply sent him a letter with conditions instead. Kyle then told the revolutionary leader he would explain the letter later and brought up the topic of the surviving Lucifenian army and discussed the issue with the members of the meeting.

The next topic was related to the Three Heroes and, after Keel determined Elluka would not become a problem, Kyle explained that Mariam Futapie was found dead by a Marlon soldier while patrolling the palace. When asked if they knew the perpatraitor that killed her, Kyle responded in the negative. With the first two topics settled, Kyle elaborated on his mother's conditions and York, outraged by Kyle's proposal, spoke out against him. In response, the King attempted to soothe his anger.

Once York was pacified by Germaine, Kyle finished explaining that if the revolutionary army led the country, they would lack political experience, unlike him; Kyle also added that he was willing to incoporate the revolutionary leaders into the new government in Lucifenia. The conference unanimously agreed to Kyle's proposal and York and Minage were given positions in his new regime while Germaine turned down the offer. Kyle humbly told those present he would work hard for Lucifenia to know the true meaning of freedom in the future.

The King then looked at Germaine with regret for turning down the chance to join his government before the swordsman laughed. Kyle asked what was wrong and she told him how he spoke differently compared to how he spoke as "Kachess" and the humbled king told her not to tease him before turning away from her. Kyle then inquired if she met the arrested princess and when Germaine told her she had not, he brought up the subject of her execution. It was decided by the meeting that "The Daughter of Evil" would be killed and Kyle declared she would be given a public execution in Millennial Square at three o'clock.

Marlon Occupation
"Do you intend to unify the whole of Evillious?" "We will come to that sooner or later."

- General George Ausdin and King Kyle

After "The Daughter of Evil" was beheaded and the Kingdom of Lucifenia was occupied, the Demon of Lust was secretly extracted from him. Shortly after, he was unknowingly possessed by the Demon of Pride from the gift hand mirror he carried. Once Kyle settled in Lucifenia and handed over administration of Marlon to his mother. Somtime after, Ney Futapie told Kyle that Germaine was Michaela's actual murderer. Determined to attain vengeance against her, he sent out a letter to Keel among others concerning his "Witch Hunt".

Later on, in the Hall of Sounds, the Marlon king considered his role in the events that led up to Michaela's death and recognized his fault for much of the bloodshed. However, after removing the handle from his mother's gift hand mirror, Kyle reconsidered his views and determined that his actions were right and were the best for both Marlon and Lucifenia.

A soldier then arrived and frantically reported that Germaine and York escaped the palace and headed southeast from the lake. Kyle realized his hidden intentions were discovered and told the soldier to stop them when they reached Retasan Fortress. The king asked about the Witch Hunt and was told there were notifications in Lucifenia and Marlon but that the sources were dubious. Kyle understood his blunder for letting the "murderer" run away and ordered the soldier to find and arrest Germaine.

In that year of EC 501, Kyle merged Lucifenia as part of Marlon's territory and attempted to eradicate the members of the Resistance. Faced with an uprising from the former revolutionaries, Kyle branded Germaine a traitor and fabricated that she intended to rebel against the new government and lead the uprising. As time progressed, Kyle added more names to the Witch Hunt. During that year, he discovered that both Elluka and Gumillia had been spying on Lucifenia and added their names to the Witch Hunt.

In order to gain the support of the merchants, Kyle began to regularly attend their banquets. Around this time, Keel began sending Kyle the novels published by his nine year old daughter, Yukina, and the blue-haired king was impressed by her capabilities. At Keel's suggestion, Kyle banned trade with Elphegort, though still permitting business transactions within Marlon, to promote the nation's economy and disassociate the nation from the Green Country's royal family.

In EC 502, Kyle asked his mother to use her Espionage Task Force to help hunt down the "witches". His mother complied on the conditions that they had absolute freedom in regards to the Witch Hunt and that Abyss I.R. select the group's head, namely Ney. Accepting the terms, Kyle had the masked group root out and capture those in his Witch Hunt Order. The following year, Kyle ordered Riliane Mouchet to recapture Retasan. After the fortress was retaken, the members of the Resistance fled to the Beelzenian Empire and Kyle demanded the Beelzenian Emperor hand over the refugees. Faced with the Emperor's refusal, political tensions rose between the countries.

In EC 505, Kyle decided to begin his planned invasion of Asmodean and Beelzenia. Knowing that Gumillia was in the Beelzenian Empire, he sent Ney and the Espionage Task Force to Retasan to find and capture the sorceress. Ney insisted on being made the fortress' commander and, despite opposition, Kyle gave the golden-haired assassin the position, expecting Ney's usage of the Glass of Conchita to reanimate the dead would bolster their offensive.

Over two months after fighting broke out in Beelzenia, Kyle reminisced at Nikolay Tolle's paintings in the Hall of Mirrors when General George Ausdin reported that Retasan fortress seemed to have fallen. Noting the general's apathetic wording, he chastised the soldier for not taking his country's affairs seriously, questioning if he was among the dissenters of the old Lucifenian military. Brushing it off, Kyle listened to the general's commentary about letting Ney command the soldiers and impatiently asked what their next move would be.

The confident king then ordered him to help reinforce their forces in Retasan and continue defending the city. George suggested recapturing it instead but Kyle explained that was inevitable, planning to reorganize their forces and mount a full invasion on all of Beelzenia. When the surprise general asked if he planned to unite all Evillious, the Marlon king affirmed it would happen in time.

He then permitted the soldier to speak and listened to his doubt that Kyle had the necessary qualities to achieve such an ideal, viewing his actions as arrogant rather than ambitious. Although angered by the rude assertions, Kyle stated he would have to accept the opinion and refused George's suggestion to be sent to the guillotine as punishment. Giving him twenty thousand troops, Kyle sent the battle-ready commander away with his orders.

Afterward, Clive entered to announce that Ney arrived to give a report. The king commanded she be sent to the Hall of Sounds. Looking back to see him leave, Kyle recalled the revolution and how Germaine was celebrated as a hero. As he began to question his actions, the anxious king took the hand mirror to soothe his confusion and regain his confidence.

Entering the Hall of Sounds, Kyle sat on the throne when Ney's arrival was announced. As she and her task force kneeled before him, he expressed his disappointment in Ney's failure at Retasan. Ney indifferently responded that the mission was more difficult than she had expected and he stated that General George would take care of the situation eventually. Curious why she came back with her mission incomplete, he noted that he had yet to recieve a report of Gumillia's capture.

Ney answered that both she and Germaine were also identified in the nation and that both had left the Empire. Surprised, he asked when they would be able to capture her and Ney stated the undead soldiers had been useless. Kyle stared, speechless, and Ney told him to give his complaints to Abyss I.R., not her. The Marlon king retorted that the Espionage Task Force should have been better and asked if she planned to hunt down the newly-found targets. Ney denied it and said she would return to Marlon and ask Abyss I.R. if she was misusing the Glass.

When Kyle voiced his opposition, Ney declared it was necessary to know the vessel's full potential for the Witch Hunt. Unable to object the reasoning because of his mother's conditions, Kyle said she was allowed but demanded the rest of the Task Force stay, saying they were needed as reinforcements and that they were unnecessary for Ney's return home. Ney complied and mischievously told to not have too much fun with them. Confused by her words, Kyle looked over to the female soldiers and realized she was calling him a pervert and angrily banged his arm on the arm of his throne.

Visitors to the Palace
Two weeks later, Kyle attended a dinner party held at the merchant Koopa's mansion, escorted by Clive. While drinking, the Marlon King watched Koopa introduce a beautiful singer to the stage and listened to her song. Recognizing the tune, he was reminded of Michaela and became upset. Although tempted to criticize her, Kyle remained silent and eventually left, feeling drunk, and head out to the mansion's courtyard. As Kyle reflected on the last five years and how soon his revenge would be complete, he was startled by the sound of a voice saying it was boring. Unable to find its source, the ringing voice gave him a headache and the King mentally lashed out that he wasn't boring.

At that time, a girl approached him, offering him black tea and a rest. Gladly accepting it, he drank it and realized it was of Marlon make. Kyle thanked her and inspected her clothes but couldn't recognize her. He enquired who she was and, as the girl continued chatting with him, he remembered she was Keel's daughter, Yukina. After noting how much she had grown, Kyle mentioned how popular her novels had become and the girl downplayed her skills. Kyle then reiterated that she was talented.

As he was about to ask her why she was there, Yukina stated she would be visiting the palace the next day and wanted to notify the king in advance. Although saying the night was still young, he agreed and Yukina left immediately afterward. After the blue-haired king mused how the troublesome child became a virtuous lady, Kyle greeted Koopa then headed for Clive, telling him to ready the carriage. During his ride back to the palace, Kyle looked out at the night sky.

The next day, Yukina visited Kyle and he with her in the Hall of Mirrors. The Marlon King, stating her travels must have been difficult, demanded she skip the pleasantries and raise her head to him. Looking at her face, he noted she looked more like her mother and, at her behest, remarked the peculiar attire of her two masked bodyguards behind her. The child explained that they were Asmodean mercenaries she met on her journey when Clive stepped forward and demanded they removed their masks in Kyle's presence.

Although bothered they refused, Kyle told his aide to stand down, trusting in Yukina's judgement of them and stating he felt safe with all the palace guards. Curious why she came, the blue-haired king listened to Yukina claim she was acting on behalf of her father. At the mention of the Elphegort embargo, Kyle clarified they were still able to conduct business in Marlon and pointed out Keel being the one who proposed the ban. Seeing Yukina flustered, he questioned why the bussinessman would send her instead of his successor, Shaw.

Assuming she was unaware he knew she had run away and was searching for a home to take her in, Kyle brushed off the child's stuttering explanations and said he'd consult her father later. He then changed the subject, asking if it was her first time at the palace and encouraged her to look around for potential new novel ideas. After reminding her that weapons were prohibited and that he'd notify the guards of her visit, Kyle watched the excited child leave.

The King then told Clive to notify the guards and to send a messenger to Keel regarding Yukina's location. When the guard questioned his judgment, Kyle affirmed that, despite wishing to please her, Keel would die of loneliness if he worried too much. As the servant went to fulfill his commands, Kyle mused how Keel was probably already aware anyhow.

Later, he showed Yukina the hand mirror, explaining how his mother gave it to him and that he had begun sleeping with it after the incident four years prior. Afterwards, Kyle offered Yukina and her companions to stay the night with him at the palace and the girl accepted.

That night, Kyle heard an explosion and rushed over towards the sound. Discovering Germaine near a destroyed window, the blue-haired king realized Yukina's intent was to help the "witches" steal his hand mirror. Furious, he accused Germaine of murdering Michaela. The warrior denied the claim and stated she was aware of the truth, saying he should abandon his blinded idea of revenge and pursue his own dream. Although shaken by her words, Kyle rejected her attempts to reason with him and ordered the palace guards to kill her before the swordswoman escaped through the broken window.

Transformation
Undaunted, Kyle retrieved another hand mirror and traced Yukina to Riliane's room, taking the secret passage in the fire place to the royal stables outside. After finding Yukina with Gumillia, the arrogant king became completely possessed by the Demon of Pride and underwent a demonic transformation. Transformed into a six-winged beast, Kyle easily sent Gumillia flying into a wall when she attempted to cast a spell on him and then flew into the night sky.

Over the course of two weeks, Kyle's transformation increased as he hunted aimlessly for the three. Finding them in the Millennium Tree Forest, the bestial Kyle attacked Germaine wildly. Fended by the swordswoman, Kyle began shifting his attacks toward Yukina. In Germaine's attempt to protect the girl, Kyle broke her sword. Despite Gumillia's attempt to exorcise him, Kyle remained unaffected and continued his onslaught. However, Michaela intervened, singing a spell song that amplified the spell's effect and successfully freed Kyle of the demon's control, rendering him unconscious.

After Kyle returned to normal and regained consciousness, he explained that his memories of the past five years were vague and that he had no recollection of the past two weeks. Learning of his possession, Kyle decided to confront his mother directly on the matters. Thanking them for their help, the blue-haired king gave Gumillia, Germaine, and Yukina safe passage to Marlon to help him uncover the truth. He later departed from Lucifenia with his newfound friends on his flagship, Royal Victory, setting their course to the Marlon island.

Praefacio of Blue
While at sea, the ship was attacked by pirates. Kyle battled the thieves alongside Germaine, who identified them as members of the Venom Mercenary Group to the king. After successfully driving them off, a giant octopus suddenly sunk the escaping pirates' ship. Gumillia advised Kyle to fire the ship's cannons at the creature's brow, and heading her advice, the group evaded the octopus and resumed their course for Marlon. Upon their arrival at Jamet, Kyle parted ways with the others and headed towards Bariti to confront his mother.

While there, he met Arkatoir and learned from him about Prim's thorough eradication of the royal family and how Arkatoir had survived and began working at the palace. Kyle's half-brother then explained that Prim had set off to Castle Hedgehog after hearing of Kyle's return. The Marlon king then asked where Abyss I.R. was and Arkatoir explained that she had died a few years ago.

After discovering that Prim was building up an army of undead soldiers through Ney and the Glass of Conchita, Keel met up with the blue-haired king and explained his belief that Prim and Abyss I.R. had been manipulating the events from behind the scenes using the vessels of sin, provoking Lucifenia and Elphegort to wage war as an opportunity to expand Marlon's territories. Kyle, refusing to believe these suspicions, stated that Abyss I.R. had died sometime ago.

Keel then showed him Kyle's last surviving painting and revealed that the portrait was of Ney and that she was Prim's daughter, Kyle's half-sister. Shaken at these revelations, Kyle declared he would confront his mother and end her reign. Yukina, having overheard him, begged Kyle to let her accompany him but he politely refused her request, saying that she was needed where she was already. Bidding each other farewell after a tender moment, Yukina promised to wait for Kyle. As he left, Keel swiftly hit the Marlon royal and promptly beat him up, warning him about falling in love with his daughter.

Afterwards, Kyle rallied an army for his planned assault for Castle Hedgehog. Finding both Elluka and Gumillia, he asked for their assistance in the impending invasion and gained their support. He later recruited Germaine to his cause. When Mikina insisted on keeping Abyss I.R.'s cat, Kyle noted how she used to act around cats as a child. With Elluka and Gumillia's magical enchantments, Kyle led his army towards the north-western fortress and battled against the undead soldiers present there. As they breached the castle, Germaine fended off the reanimated soldiers while Kyle and two of his men rushed up the clocktower.

Encountering his mother again after five years at the top of the spire, the blue-haired king saw Ney flee and ordered his troops to go after her. Alone with his matriarch, Kyle interrogated Prim and the queen dowager revealed her past and the motives behind her schemes, confirming her desire to expand Marlon's territories and have Kyle rule as a "champion king". Unable to believe his mother's words, Kyle said that she had gone insane and, in response, Prim revealed the Mirror of Lucifenia in her possession, and expressed her intent to have the Demon of Pride repossess him.

Prim then mocked Michaela and Margaret, saying that they were like the Clockworker's Doll and Eve Moonlit, the origin of all sin. As he listened to her words, Ney returned and, after being ignored by Prim for murdering her pursuers, snapped and killed their mother.

Kyle then watched Ney succumb to the Demon of Gluttony and transform into a new attire before attacking him. Unable to defend against Ney's frenzy, she stabbed him in the chest and the king collapsed. As Ney prepared to finish him off, Germaine arrived to distract Ney and Kyle used the opportunity to fire the rocket glove Chartette Langley gave the swordswoman. With Ney incapacitated from the attack, the two bound and captured the assassin while Kyle contemplated what to do with her.

That night, Kyle had a dream about Ney, envisioning her as a child. After the girl apologized for her actions and wished to be reborn with him, Allen, and Riliane again, Kyle saw the Demon of Gluttony appear and laugh at her. Saying her wish would never be granted, the Demon took Ney's hand and told Kyle they would meet again, calling him the "Soul of Adam".

The blue-haired king begged Ney not to leave as he watched her become swept away into the sea. Awakened from his dream, Kyle rushed to where Ney was confined and found Keel unconscious and his half-sister dead. He later had both Prim and Ney buried together in a cemetery and received a letter from Yukina, explaining that Mikina had gone missing and that she had gone off in search of her.

Later Life
"He still looked happy."

- Yukina regarding Kyle's later years

Kyle later abdicated the throne to his brother, Arkatoir. He traveled the world as a painter for some time, living his childhood dream, before reuniting with Yukina. The two started cohabitating in Lucifenia, and the former king lived a happy life with her.

Legacy
"Oh well. It’s a very interesting book. I got to learn about my ancient ancestors."

- Gallerian Marlon referencing Kyle and his family

Kyle's actions would later be detailed by Yukina in her novel "Daughter of Evil". His descendant, Gallerian Marlon, would read Yukina's novel at the behest of his friend, Ma, and the judge was satisfied with learning more about his ancestor who had removed himself from the royal family.

Personality and Traits
"I’m proud of my position as king. One word from my mouth can either save my country or plunge it into Hell. It’s a heavy responsibility. Although I walk the path paved by my mother, in the end, she is still unsatisfied."

- Kyle

Kyle was an honest and caring individual trapped by the will of others. He lacked the desire to be king, wanting to become a painter. However, his mother's machinations diminished his confidence and forced him to accept the role as monarch after his father's death. Kyle despised Prim for her cruelty and was constantly frustrated by his inability to control her methods. As a result, he held the lingering notion of escaping the royal family and living like a commoner with a family. Despite this, he was proud of the responsibility he had as Marlon's king and took it very seriously.

He disliked being teased and was easily embarrassed by comments made about him. Kyle's pride, when influenced by the Mirror of Lucifenia his mother gifted him, turned into hubris and fueled his arrogance and conviction that he could do no wrong. The mirror acted as an escape to diffuse Kyle's confusion and dispel his mediocrity complex that plagued him. Kyle held a pessimistic view on politics, choosing to back the Lucifenian Revolution and reject Riliane's marriage proposal rather than believing in others to understand his actions.

Skills and Abilities
"And in the Kingdom of Marlon as well, although officially the ruler is the young King Kyle, the real power is in the hands of Queen Dowager Prim, his mother."

- An aristocrat speaking about Kyle

Kyle was a skilled duelist, showing his capability with a sword during the Lucifenian Revolution and while battling Germaine five years later. He was also an adequate painter with his painting of Ney catching the attention of the business savvy Keel Freesis. He was also an experienced politician and took it upon himself to help govern the rebuilding Lucifenia.
