Arkatoir Marlon was the parliamentary secretary of the Kingdom of Marlon and the half-brother of Kyle. During the political unrest over his father's heir, Arkatoir's claim to the throne was renounced and he went into seclusion. The former prince later returned to parliament and served under his half-brother's reign, becoming involved in unraveling the conspiracy within the Marlon government.


Early LifeEdit

"This will be my fight."

Arkatoir was born into the Marlon Royal Family around EC 482, the illegitimate child of the king of Marlon and a Beelzenian mistress. He was taken in and raised by the royal family at Marlon Castle in Bariti along with his father's many children. After the king died around EC 490, the dispute over which of his heirs would succeed him grew bloody as his numerous half-brothers disappeared or were mysteriously killed; to prevent Arkatoir from also being killed, his mother renounced his birthright and he became a regular citizen.

Sometime after his surviving half-brother King Kyle was crowned king in EC 494, Arkatoir learned that the Queen Dowager Prim was heavily suspected for the other heirs' murders. Reluctant to become a peasant for the rest of his life, the former prince returned to the castle and became part of the royal parliament. Serving under his half-brother, Arkatoir proved his excellence for the King and Queen Dowager and became the parliamentary secretary.

During this time, Arkatoir encountered Prim's court mage, Abyss I.R., and became one of the many unnerved by the vile sorceress. Once Kyle asked him why he was in politics despite the danger, Arkatoir made clear that while he was grateful to be removed from the family dispute, he still wanted to aim for something more than a peasant's life in spite of the dangers.[1]

The King ReturnsEdit

"It seems you have served me well in my absence."
―Kyle to Arkatoir[src]

After Kyle chose to stay in the occupied Lucifenia at the end of EC 500, Arkatoir continued his official duties under Prim's authority. During his tenure he met the Freezis Family head maid Gerda and became infatuated with the older woman. In EC 505, he heard the declaration of Abyss I.R.'s death and internment in the Left Chapel. A few days later, word came that King Kyle planned to return home, and Arkatoir took note as Prim suddenly left for Castle Hedgehog for alleged health reasons.

A few days later, Arkatoir received Kyle in Middle Tower and the two discussed Prim's recent departure, as well as Kyle inquiring about the amount of soldiers they could assemble to the castle on a moment's notice. Although puzzled, Arkatoir also answered to Kyle's inquiries about Abyss I.R., relating her recent death and showing him the sight of her grave. Once pressed, Arkatoir also unearthed the body for Kyle to see, albeit shocked by the request.[2]

Arkatoir later joined Kyle as the King prepared to meet with Keel Freezis in the Right Palace, although he was shortly after charged with giving Keel's son, Shaw, a tour of the castle so that Keel and Kyle could speak privately. When Gerda was instructed to join the tour, Arkatoir became flustered and hurried Shaw, Gerda, and himself out of the audience chamber. After the tour, and once Keel had departed with his servants, Arkatoir returned to Kyle's side and suggested the king rest, as he looked unwell.[3]

On Kyle's orders, Arkatoir assembled five thousand ground troops and the king left with them for an assault on Castle Hedgehog. On Kyle's return, Arkatoir learned of Prim's apparent demise during the fighting due to a mage who escaped. Two weeks after Prim was formally buried in Left Chapel, Arkatoir saw Kyle deriding himself by her grave and tried cheering him, before the two were interrupted by Shaw with news of Yukina Freezis' recent departure from Marlon.[4] In EC 510, Kyle established Lucifenia's independence from Marlon and then abdicated the throne, with Arkatoir was crowned in his place.[5]


Following Arkatoir's death, he was succeeded by his own children. In the wake of his reign, future generations of the Marlon Royal Family had varying hair colors in contrast to the characteristic blue hair of male generations from the previous centuries.[6]

Personality and TraitsEdit

"A nation's king shouldn't say such things. You shouldn't be showing the appearance of such a bearish king, at least in front of the people."
―Arkatoir to Kyle[src]

Arkatoir was an honest, ambitious, and selfless man. Since his youth, the former prince aspired to be something more than a simple peasant farmer. As a result, he was reluctant to give up his claim to the throne, though grateful to have avoided being killed during the political unrest. Despite this, he had no issue being a civil servant to royalty and loyally served the royal family who ousted him. Arkatoir was also very daring, gladly demonstrating his abilities in the political field and challenging the risks to his own life.

Despite this ambition, the former prince was very modest and easily became embarrassed when praised.[7] Arkatoir was similarly very kind-hearted; despite only being half-siblings, Arkatoir demonstrated his love and respect for Kyle and supported the self-doubting king during his reign. This support included supplying him with crucial information and acting as his adviser whenever needed. As a result, the two developed a close bond and shared their thoughts and feelings rather casually with one another.[8]

Skills and AbilitiesEdit

Having attained the position of parliament secretary at a young age, Arkatoir was skilled in politics and an extremely competent official, impressing even the critical Queen Dowager Prim. Committing government and military matters to memory, he was a capable aide and adviser as well. Due to his royal blood, Arkatoir was a legitimate heir of the royal family and became influential as King of Marlon after Kyle's abdication, although he had relinquished his birthright and lived as a commoner for much of his early life.[9]

Character ConnectionsEdit

Kyle Marlon: Arkatoir's half-brother. Although not growing up with Kyle as brothers, Arkatoir nonetheless cared greatly for his relation and provided him aid and formal advice whenever possible, making use of his political power. Understanding the great responsibility that Kyle held, he also reassured the king in his times of uncertainty and looked after his health.

Gerda: Arkatoir's crush. After meeting Gerda, Arkatoir became infatuated with the woman despite her age. Due to the many oddities of the relationship and its novelty, the official would become embarrassed whenever the subject was broached.


Conceptualization and OriginEdit

  • Arkatoir's surname, Marlon, is a reference to Mammon, the patron demon of Greed.
  • Arkatoir's name is partially inspired by the name of his representative Fanloid, Akaito, with Arkatoir's romanization containing "a", "ka" and "to".


  • Despite being a few years younger than him, Arkatoir strongly resembled Kyle, looking almost exactly like him save for the red hair he received from his mother.[10]
