Arthur Boyle

is a Third Generation Fire Soldier of Tokyo's Special Fire Force Company 8.

Appearance
Arthur is a young man of average height with shaggy blonde hair and blue eyes with white pupils, similar to Shinra. He tends to style his hair upwards into a ponytail when in a fight, so that his field of vision would be clearer. When Arthur was first introduced, he wore a dark jacket, with a button on his collar, shaped like a cross-like insignia, light shirt, dark pants, a belt and dark shoes. He was later presented with a bunker gear, a protective outer jacket and trousers. Arthur carries a scabbard alongside him, in which he keeps his blade-less sword. Parts of his outfit, are coated with blue lines. Arthur wears a dark green jumper with a hoodie, which he puts on his head instead of a helmet. The buttons of his protective jacket are in the shape of cross-like symbols. Arthur's outfits contain patches with "8" on them, to signify his affiliation to the 8th Special Fire Brigade. He also dons a neck protector and protective gloves. When attiring the 8th bunker gear, Arthur chooses not to wear the helmet, as it doesn't fit his image of a knight.

Personality
Arthur is confident in himself as a Third Generation. So much that he appears arrogant and cocky all the time, notably for his habit of refusing to use honorific speech regardless of who he is talking to. He has a medieval-like complex, referring to the girls he meets as princesses and the Special Fire Cathedral 8 as his castle. Arthur sees the world in a different light; he believes the pigeons to be griffons and that he was successful in slaying dragons. According to Shinra, he is inexplicably popular with the girls and seems to always have a silent and mysterious façade, though Shinra thinks he's just too stupid to articulate anything. Arthur often bickers with Shinra Kusakabe on which are superior: knights or heroes. He prefers to go his own way, rather than do things the way other people think he should. Arthur takes great pride in Excalibur, and in his personal tool's absence, his power is directly linked to how 'knightly' he feels, which includes how sword-like any acquired tool look. Due to his attitude and casual demeanor, Arthur tends to make bad impressions on people. He was shown not to be bothered by human antics. Despite his repetitive bickering with Shinra, Arthur is capable of putting the differences between the two aside and work as a team. Arthur is usually nonchalant even while struggling in fights.

Other than his eccentric demeanor and obsession with medieval-related things, Arthur is also for his lack of intelligence, repeatedly been referred to as foolish and lacking in common sense. Shinra's mocking in this regard turns out to be true, as he is utterly incapable of anything of requires heavy brain work, quickly burning out from paperwork and relies almost entirely on natural combat instincts to fight, as he is unable to generate nor comprehend complex strategies. Like the other brigadiers, Arthur has a high sense of justice, which he correlates to his persona of being a knight. Arthur has a habit of repeatedly saying "Hmph" in response to people, coming across as stubborn. Arthur has a tendency to mock his fellow brigadiers in a joking way.

Abilities
Arthur is an exceptionally strong Fire Soldier, that possesses incredible raw physical strength, being capable of repelling an Infernal with a single punch. Arthur also possesses keen kinetic eyesight, allowing him to track the smallest movements and react quickly. However, this results in Arthur instinctively blocking and parrying any attack he sees, leaving him vulnerable to illusions and misdirection. Attributed to his speed, he was fast enough to react to Shō Kusakabe's Severed Universe, though he wasn't able to entirely dodge it.

Ignition Ability
Being a Third Generation, Arthur has been identified by individuals as having a strong will of fire. By raising the temperature of the flames he creates, he can fabricate and control plasma, a rarity as few can heat flames into a plasma state. The effectiveness of his ability which either elevates or diminishes in relation to Arthur's disarrangement from reality. The more delusional he is the stronger Arthur becomes, while being pulled back to reality reduces his strength. Being able to use his Ignition Ability on hilt-like objects, Arthur can weld, cut through metal, and generate electricity. He mainly uses his ability on his blade-less sword Excalibur, which is most effective using his right hand and cannot be easily extinguished by an experienced Second Generation. Using it, he can deflect and fend off against flames. The downside of his ability, linked directly to his warped worldview, is he is incapable of using his abilities correctly unless the tool he wields resemble the hilt of a sword.

Background
His family opened a small restaurant to make a living. However, due to an accident when a guest got food poisoning and later a fire destroying the whole restaurant, they struggled with their life. His family's restaurant appeared in the news and they couldn't work. His mother tells him to call his father to tell him dinner is ready. When Arthur gets his dad, his Father is sleeping with his hat over his face. Waking his father, he asks a question which his father smiles at and covers Arthur's face with the hat. His father tells him to look into the hat. Arthur's imagination takes over and he sees various things such as a Castle, Knights and his father and mother during a Ball. The next morning he finds a letter from his parents telling him that they have gone on an adventure to save the world. While they are gone he is king. Arthur attended the Special Fire Force Training Academy alongside Ogun, where he often bickered with Shinra over their beliefs.

Plot
Arthur arrives at the Special Fire Cathedral 8, where he runs into Shinra Kusakabe and the two begin fighting. As their fight is taken to roof, he meets Iris and Maki Oze, followed by Takehisa Hinawa, who instructs him to spar with Maki in order to test his abilities. Unable to beat her combat skills and ability, Arthur gives up. After eating at Ippudo Ramen, Arthur is offered a battleaxe, but refuses to take it. When the brigade is notified of an Infernal in the Iriya District, he departs to the scene. While on route, Akitaru Ōbi instructs Arthur and Shinra to conceal their weapons in public, much to his confusion. After their arrival, Akitaru pulls the two aside for disobeying orders, where Arthur questions the instruction, leading Akitaru to justify his reasoning. After their conversation, a burst of flames emerges from the apartment, prompting the brigade to storm the building and find the Infernal. Arthur volunteers to put the man out of his misery and impales his core. Immediately after that, the ceiling begins to collapse, but the brigade escapes unscathed.

Arthur participates in the Rookie Fire Soldier Games. When the simulation exam starts, he charges towards the building and uses his sword to slice his way in. After one of the entrants bombards the building with his ability, Tamaki Kotatsu falls onto him, which gets the two into an intimate situation. Following his beliefs, the boy allows Tamaki to take the lead when exploring their current location. When the two are attacked, Arthur jumps in to defend the girl. He then charges in, believing Joker to be part of the exam, despite Shinra's warnings, but does not land a single blow. When the man uses an unknown substance to put their lives in jeopardy, Arthur uses his sword to cut a hole in the ceiling, allowing Shinra to evacuate them all to safety, with Arthur being caught by his team-mates in a blanket.

The following day, Arthur accompanies Shinra on his mission to rescue a dog, who was reported to be stuck in a tree, and afterwards, helps Mamoru hand out balloons to children. The two then learn of an accident in the courthouse from Takehisa, who was moving to the scene with the rest of the brigade. Grabbing a lift from Shinra, the two Fire Soldiers face Setsuo Miyamoto, with Arthur hitting the opponent with a backwards fist and delivering a collaborative attack alongside Shinra. When the brigade catches up to Shinra, Arthur and the rest find themselves in a confrontation with the Special Fire Force Company 5. Tōru Kishiri mocks Akitaru, which leads to Shinra and Arthur jumping in, but Maki and Takehisa detain the two. A stand-off between the brigades is then catalyzed, but the two depart without any signs of struggle.

VS. 5th Special Fire Brigade arc
The following day, Takehisa begins training the Fire Soldiers, having Arthur spar against Maki. Later, after Iris has gone missing, the 8th Special Fire Brigade infiltrates the Special Fire Force Combine 5, where Arthur finds himself in a fight against Setsuo, who was modified by the 5th Special Fire Brigade. Mid-way into the fight, Arthur realises the whole time he had been fighting with Excalibur in the wrong hand, which is why he had been struggling so much. Before Setsuo could execute his final attack, Arthur finishes him off in a dash with Flash of Lightning, successfully exterminating him. After the two brigades ordeal ended, a dinner party was organized between them as a sign of reconciliation. As Maki created some of her Pusu Pusu and Mera Mera, Arthur sliced all of them in half, stating that Takehisa told him to destroy them whenever she creates them.

VS. 1st Special Fire Brigade arc
Later at the brigades church, Akitaru instructs Arthur and Shinra to infiltrate the Special Fire Force Company 1 and uncover any secrets they may be hiding. A while later, the two and Maki arrive at the 1st Special Fire Fighting Cathedral, along with Tōru Kishiri and Takeru Noto. As they walk inside, they meet Karim Flam, followed by the other Company Lieutenants and Captain of the 1st. When Burns agrees for the newcomers to test their abilities, they go out to the courtyard and begin sparring. After Rekka and Takeru's fight, Arthur and Shinra confront Burns. Confident that he will defeat Burns, he charges at him heroically, but to no avail, as Excalibur is blocked and repelled, much to Arthur's confusion. Afterwards, Shinra tries his luck against Burns but is also defeated with ease, and the newcomers are welcomed to training with the 1st for the month.

On the fifth day of training, the brigade is notified of the appearance of Infernals, and departs with Shinra alongside Karim and Company 1 to the scene. When they arrive, Karim instructs the two to stay put, which they do, until Shinra notices a priest creating an artificial Infernal and takes chase after the culprit. As they stumble across Karim and Rekka, Arthur spontaneously confronts them about it, but is quickly subdued by Shinra. After the mission ends and they arrive back at the Cathedral, Arthur, still annoyed at Shinra for stopping him, questions why he did so. Shinra explains that by confronting them in the alley would have led to their defeat, as they were outnumbered by the amount of 1st Brigade members. The two then resolve a plan to infiltrate and investigate Rekka and Karim's room, starting with Karim. As they arrive, they discover the same Bug used to create the artificial Infernal, but at the same time are discovered by Karim. As Karim points out he is on their side, hiding the Bug on purpose to lead them there, he reveals that the real criminal is Rekka. A little while later, Arthur and Shinra await Karim in the corridors, and ask for permission to help with the capturing of Rekka, to which Karim tells them to do what they like. While hunting for Hoshimiya, Arthur gets lost in the city. The Fire Force has to file a missing person's report.

In the aftermath of the event, Arthur assists in the reconstruction of the destroyed houses, welding materials together with his Mini Excaliburs. When Benimaru begins to rampage through the town, hunting down Company 8, Arthur and Hinawa work together to challenge him but are quickly overpowered. Once the battle between Akitaru and Benimaru ends, Arthur walks through Asakusa with Konro and members of Company 8. The Knight King is the first to realise that Hikage is an importer, attacking the spy and revealing their true identity. Asakusa irrupts in flames. Akitaru instructs his team to assist the villagers evacuating, but they are immediately attacked by a flaming arrow. Shinra and Arthur then begin searching for the shooter.

Realising they need to start coordinating their attacks with one another and adjusting their strategies, the Fire Soldiers manage to get the upper hand. When Arthur corners Arrow, Haran intervenes and gets slashed by Excalibur. Wounded, Haran swallows a Bug and transforms into an Infernal. With his new found strength, Haran overpowers Arthur and the Soldiers are engulfed by his fire ball. Jumping back into the fight, Arthur attempts to cut his horns, but is unsuccessful, before being repelled again. Haran's assult is interrupted by the arrival of Benimaru.

However, Arthur's training allows him to notice which attacks are mere tricks and which ones are genuine, preventing him from reacting rashly as he did during their previous battle. Arthur uses his Iai-Calibur technique to dispatch Mirage before he can attack an unsuspecting Hinawa, defeating the cultist in a single stroke. Both Hinawa and Arthur advance into the darkness and question who Jonah is.

Arthur later arrives to protect a near-fatally wounded Shinra from Haumea. Noticing the devil's injuries, Arthur tells him not to die.

Company 8 choose to save Shinra's life instead of pursuing their enemies, rushing him to Company 6's clinic for medical attention.

Despite his harsh words, Arthur continues to attempt reason with Shinra by countering his confused arguments for becoming a Devil, much to Hitohashirame's fury. This fury presses her and Shinra rushing in to finish Arthur, who counters with a barrage of strikes before finally telling Shinra to embrace being a hero once again to protect what he loves.

With the battle over, Arthur and Company 4 attempt to gain a better understanding of the situation. Arthur notes that the members of Company 4 who attacked Shinra were likely controlled by Haumea.
