Arthur Cinco

---

• AArthur was born from a challenge Nyarly gave me. I had approximately 10 minutes to draw a character that came entirely from me—any species, any gender. I made a very ugly sketch of a bunny boy sitting on a desk chair, but she took my sketch and polished it until she gave me the first awesome reference of Arthur. From there, everything began. 👍
• There is no other Arthur in the universe. Just like Kazuya or the other Orion, they are beings that exist outside the order of destiny.
• Arthur stutters when he is nervous.
• He gets along well with shadow creatures, as he grew up with them. Sadly, because of this, his parents believed he had some kind of schizophrenia during his childhood..
• Arthur enjoys writing BL fanfiction under the pseudonym Anthur. This name comes from the word Anthurium (Anturio), which subtly reflects that he is a boy rather than a girl writing the novels. Even so, many readers still believe he is a girl because of his way of expressing emotions.
• He is able to dilate his vocal cords to sound like a girl. (In reality, he tries not to use this “skill” since it embarrasses him a lot.)
• Arthur cannot eat any kind of meat (unlike other anthropomorphic rabbits or hares), so his diet mainly consists of fruits, vegetables, and even soybeans. Despite this, he developed fangs similar to those of predatory animals—something that remains a mystery even to his mentor and father, Kazuya..
• During the arc called 》Saturday《 Arthur got Otomodachi from Cyr However, he is unable to control his Persona as well as he would like, so he avoids summoning it.
• Although Arthur was previously shown to smoke out of necessity, he now smokes much less. The reason is that Silver once made him smoke something from his universe, which made Arthur feel extremely ill—so much so that he ended up completely K.O. and unable to remember anything about that incident. Since then, Arthur refuses to put anything unfamiliar in his mouth. (Lesson learned.)
• I always draw Arthur like an idiot… but he’s not that much of an idiot. ⍩ ( He’s actually pretty intuitive)

🌟(Arthur and Kazuya's past Arc)🌟
Arthur was born on March 10th into a large family formed by his parents and eleven siblings (nine boys and two girls). As a tradition, all male children were named after their father, Arthur, with an additional number indicating their place within the hierarchy of male offspring. Arthur was the fifth male child, and thus named Arthur Cinco (5)—although in reality, he was the seventh child overall.

Among his siblings, Arthur was noticeably small. His parents were concerned about his apparent weakness, both physical and intellectual. As a result, Arthur spent most of his time under the care of his mother and his two older sisters, learning from them and, more importantly, mimicking their daily activities.

It was during this time that Arthur met Kazuya, a homunculus and walker between universes, better known as a shadow—or the Lord of Shadows. On a night of heavy rain, Arthur secretly left the house in an attempt to help his mother by fetching milk. Unsupervised and unseen, he became lost in the vastness of the farm. He quickly caught a cold, fell prey to fever, and wandered aimlessly until he reached an old barn.

There, by chance, he encountered Kazuya, who was also sheltering from the storm. Instinctively, the homunculus tried to drive the child away. However, Arthur showed no fear toward the creature before him. Kazuya soon noticed how weak the little rabbit was and understood that, like himself, the child was only seeking shelter. He allowed Arthur to stay with him for the night.

Unfortunately, Arthur’s fragile state and raging fever meant that he was destined to die that night. Realizing this, the shadow chose to defy death itself. Kazuya cheated fate, protecting Arthur’s soul and granting him a second chance at life.
Arthur has no memory of this event, nor does he realize that he technically died and returned to life. Only much later would he begin to understand why, in every universe he visits, he is unable to find another version of himself. The fate of all Arthurs was to perish at an early age. He alone is an error in the logic of destiny—just like Kazuya—existing as the only one.

The next morning, Arthur’s parents found him safe among the hay, as if nothing had happened. From then on, he continued to live under the watchful presence of the shadow, who had grown fond of him.

Arthur learned to recognize the shadow by calling him “Azu” or “Azul”, as he struggled to pronounce Kazuya. A bond formed between the child and the homunculus. Unfortunately, Arthur’s difficulties interacting with his older siblings, his habit of speaking to himself, and his tendency to play with walls alarmed his parents. Fearing a deterioration of his cognitive and social abilities, they decided to leave the farm and move the family to the city.

During this period, Arthur seemed to forget his “imaginary friend.” However, he still lacked social skills and remained silent and vulnerable around other children. It would not be until he met Orion, and later Akari, that the young rabbit began to develop emotional attachments and gradually improve his ability to connect with others..

🌟The boys on Ice (The Other Orion's arc)🌟

Arthur was no longer a silent child. He grew into someone outspoken, emotional, and temperamental. His circle of friends remained small, consisting only of Orion and Akari—especially the latter, with whom he spent most of his time. Arthur often became overprotective of them, placing himself in exposed positions, sometimes acting like a savior, other times like a scapegoat, rarely with positive outcomes.

Wanting to stay close to his friends, Arthur chose to remain in the city while his parents and siblings returned to the family farm. Although he deeply missed his family—especially his sisters—he tried not to worry them. To support himself, he began taking on sporadic jobs outside of school hours.

During the academic year, however, Arthur’s grades began to decline. He eventually lost the scholarship that allowed him to stay enrolled. Although he finished the school year, he accumulated a debt for the semester that the scholarship had not covered. It is known that Arthur worked to pay this debt, though he was always vague and evasive when asked about the nature of his job.

As for his hobbies, Arthur showed a natural affinity for swimming. Unfortunately, due to the city’s cold climate and financial limitations, he was only able to practice in indoor pools and eventually abandoned the hobby altogether. He remained physically active through boxing, a discipline that helped him develop strength and endurance.

Arthur also showed a deep interest in literature, particularly romance novels and BL fanfiction. A self-described daydreamer, he writes frequently but refuses to publish under his real name, choosing instead to remain anonymous behind a pseudonym.

He began to suffer from episodes of insomnia, which became evident through the dark circles beneath his eyes. While it is speculated that this contributed to his declining academic performance, no clear correlation has been confirmed. Arthur does not take sleeping medication, but he admitted to starting smoking after the insomnia began.

It was during this period that Arthur faced a devastating loss.

Orion—his childhood friend and a rising star in ice skating—discovered Arthur’s struggles with tuition and the nature of the work he had been doing to survive. Enraged and desperate to make him react, Orion confronted Arthur in an alley and struck him.
Overwhelmed by the frustration and disappointment in Orion’s eyes, Arthur did not fight back. Instead, he asked Orion to stop interfering, insisting that he needed to move forward somehow.

Before leaving, Arthur threw back the ice skating competition ticket Orion had given him months earlier. From that moment on, the two stopped speaking.

Shortly after, Orion died in a plane crash on his way to that very competition—one where he had wanted both of his best friends by his side.

Arthur fell into a deep depression, consumed by guilt for the loss of his friend and for never having reconciled with him. Akari, with his own emotional duel, blamed Arthur for Orion traveling alone.

Desperate to see Orion again, Akari resolved to do whatever it took—even if it meant using Arthur. Terrified of losing his last remaining friend, Arthur complied with Akari’s wishes. Together, they attempted to resurrect Orion through alchemy.

What emerged from the ritual was a homunculus that used Orion’s body as a vessel: a mischievous and malevolent entity capable of delving into the skater’s memories.

🌟Persona and Leader-chan Arc🌟

Lets talk about Saturday's lore here

🌟Kazuya and Sigillum arc🌟

Disclaimer: This lore section were created collaborating with Nyarlylicious. My memory is fragile, and I've tried to explain what happened as accurately as possible. Even so, there may be gaps or inconsistencies in this part, as I did not fully saved all the information related to this arc.

During the events of “Saturday,” Kazuya began to suffer episodes of severe instability. Due to his inner nature as a homunculus and Lord of Shadows, and his deep connection to the collective unconscious—which had become increasingly volatile—his mental state deteriorated rapidly. As a result, Kazuya entered a state of extreme aggression, attacking people indiscriminately and placing our heroes in a situation where they had to stop him before an entire city was destroyed.

At that time, Kazuya took on the role of a ruler with almost villainous vibes, driven by the corruption of the collective unconscious and his own shadowy nature. He hid himself within a Japanese temple. (While I vaguely recall it being a specific one, due to memory limitations and some research, I chose to reference Daigo-ji Temple in Kyoto as the location but I'll be wrong, sorry.)

The group of muses was then faced with a cruel dilemma: they needed to stop Kazuya without harming him. However, they were fully aware of the magnitude of his power and knew that, if necessary, they would have to take extreme measures to prevent him from destroying the city.

Unfortunately, all attempts to reason with Kazuya failed, and they were forced to confront him directly. During this clash, Arthur—standing on the side of the heroes, yet possibly seen as a traitor for defending Kazuya—was forced to act quickly to prevent them from killing his mentor and father.

At that time, Arthur was still studying Kazuya’s teachings on alchemy. In his readings, he recalled a forbidden seal known as Arbor Floreci Sigillum (Latin, literally meaning “Seal of the Blossoming Tree”).

This seal safeguarded a branch of Irminsul, preserved through alchemy under the illusion—and hope—that the sacred tree could one day be restored to reality. Arthur broke the seal using his own blood, releasing its power and giving birth to an enormous cherry blossom tree. This tree encapsulated Kazuya in his frenzied state, stopping the battle before further harm could be done—or before Kazuya could destroy everything around him.

The cherry blossom tree became connected to Kazuya, granting him what he had long lacked: a heart. At the same time, it bound itself to Arthur through a scar on his arm. Combined with the sacred tree’s power—still immature and incomplete—this bond allowed Arthur, through dreams, to perceive Kazuya’s perspective and inner suffering. In doing so, he was meant to help heal Kazuya’s mental and emotional wounds (though this was never fully realized in the story /cough/)

Anyways, because of this, the magical entity known as Sigillum manifested as compassionate and empathetic toward both Arthur and Kazuya, strengthened their bond as father and son and granted them certain special abilities.

One example of this is Sigillum’s power to unite the mortal and the divine. Thanks to this, the Other Orion remains unable to approach Akari and Arthur. Additionally, Sigillum on their actual arc assists Arthur by allowing him to speak the languages of different universes in the blink of an eye. However, this ability applies only to speech—it does not extend to reading or writing. Those skills Arthur must still learn on his own.

🌟The traveller of the Mirror🌟

Arthur walks between universes through mirrors that reflect not only the worlds he crosses, but fragments of himself as well. Using the feathers of Kazuya’s wings, he moves forward, searching for a homeworld that fate erased long ago.

Some mirrors lead to kindness, others to suffering. Still, Arthur continues, driven by a quiet hope and an even quieter fear of standing still in the forgotten.

His heart is now a book of memories—of those he loved, those he lost, and those he will never meet again. Each universe leaves its mark, each page a reminder that even if no reflection is ever the same, his journey remains real.

And somewhere beyond the mirrors, he believes he is still being remembered.
