Lore & Background

Arthur Boyle was abandoned by his parents after their small restaurant burned to the ground, leaving them to travel the world. This abandonment fueled his delusions of being a knight king, a fantasy that directly powers his Ignition Ability. As a third generation pyrokinetic, he fabricates and controls plasma, with his power increasing the more detached from reality he becomes. He channels this energy through a sword hilt medium he calls Excalibur, which allows him to cut, wield, and manipulate electricity. His name and abilities are explicitly inspired by the legendary British ruler King Arthur. Arthur developed a bitter rivalry with Shinra Kusakabe back in their training days that continued after joining the same company, though it later toned down to a more friendly one. During the final battle against the White Clad, his delusions were augmented by Adolla leaking from the Great Cataclysm. He defeated Dragon in an epic battle that ended with him fatally wounded and drifting out of Earth's orbit while unknowingly infusing life into Excalibur.

In Their Own Story

The training grounds were quiet except for the crackle of plasma. Arthur Boyle stood opposite Shinra Kusakabe, their bitter rivalry already sparking. 'A knight king does not lose to a devil,' Arthur declared, raising the hilt he called Excalibur. The air shimmered as he fabricated a blade of pure plasma, its edge humming with electricity. Years later, in the final battle against the White Clad, that same delusional conviction reached its peak. With Adolla leaking from the Great Cataclysm, Arthur faced Dragon in an epic confrontation. He struck with everything he had, his delusions making the impossible real. The battle ended with Arthur fatally wounded, drifting out of Earth's orbit. As he floated away, he unknowingly infused life into Excalibur, his legacy carried forward by the blade he had willed into existence.
