Description
Arthur Boyle is a seventeen-year-old Second Class Fire Soldier serving in Special Fire Force Company 8. He stands 174 centimeters tall with a lean, muscular frame, shaggy blonde hair that often covers his eyes, and piercing blue eyes with distinctive white pupils. During battles, he ties his hair into a practical ponytail for unobstructed vision and refuses to wear a helmet, as it conflicts with his self-styled knightly image. He carries a bladeless sword hilt called Excalibur secured in a scabbard, and his firefighting gear bears the number 8.

Born on July 10 to parents who ran a struggling restaurant, Arthur’s childhood was marked by financial instability. A catastrophic fire and subsequent food poisoning scandal led to media backlash and economic collapse, culminating in his parents abandoning him with a note declaring they were on a mission to save the world and naming him the king of their ruined home. This trauma forged his knightly persona, a coping mechanism that reframes reality as medieval fantasy. He addresses women as princesses, interprets pigeons as griffons, and views his squad’s headquarters as his castle.

As a Third Generation pyrokinetic, Arthur generates flames from his body and superheats them into plasma, which he channels through Excalibur to create an ultra-high-temperature sword. His combat effectiveness surges with the intensity of his delusions; the more he feels like a true knight, the more powerful his abilities become. Conversely, disrupting his fantasy or using his non-dominant hand dramatically reduces his performance. He possesses immense physical strength, speed, and durability, allowing him to send large Infernals flying with a single punch and react to lightning-fast opponents. He has trained under Benimaru Shinmon to hone his battle reflexes and kinetic vision. His signature techniques include the Purple Lightning Flash and Earth Divider, the latter capable of cleaving landscapes. He can also create disposable tools called Mini Excaliburs from plastic sheets.

Arthur is confident yet stubborn, often disregarding orders that clash with his chivalric code. He is infamously unintelligent when it comes to paperwork and strategy, leading his comrades to label him an idiot, but his simple-mindedness occasionally grants him flashes of keen intuition that pierce through deception. His rivalry with Shinra Kusakabe, framed as knighthood versus heroism, fuels mutual growth, and he has been known to steady Shinra against despair. He serves under Captain Akitaru Oubi and Lieutenant Takehisa Hinawa alongside Maki Oze, Iris, and Viktor Licht.

In a climactic battle against the adversary Dragon, Arthur fully embraces his knightly identity, defeating Dragon but suffering catastrophic injuries including the loss of his left forearm and lower body. He drifts into space but eventually survives, with his wounds mysteriously regenerating. Later, he reunites with his parents in the Netherworld, where they are raising three new children, stirring unresolved anguish over his past abandonment. As the guardian of the Fourth Pillar, Arthur’s journey intertwines tragic roots, psychological fortitude, and a gradual reconciliation of fantasy and reality, cementing his legacy as both a deluded knight and a genuine savior.
