Ruro Arthur employs dual pistol Excaliburs, embodying a pragmatic, methodical combat style shaped by diverse life experiences that hone his tactical precision and unflappable composure. He navigates conflicts with a focus on calculated outcomes, masking concern for allies beneath strategic choices or understated gestures that serve collective goals. His aloof reputation belies a quiet commitment to his team’s survival, though he often sidelines his own safety—a habit subtly countered by Bethor, his sharp-witted fairy companion.

Bethor’s acerbic critiques and intellectual rigor cloak a fragile constitution and unspoken anxiety over Ruro’s self-neglect. Their partnership thrives on a bedrock of unacknowledged dependence, with Bethor’s covert vigilance nudging Ruro toward balancing mission rigor with self-preservation.

Tasked with dismantling corrupted Excaliburs, Ruro specializes in reconnaissance and firearms-driven tactics, adapting seamlessly to unpredictable threats. His dry humor surfaces during missions demanding improvisation, such as neutralizing an Arthur whose reality-warping Excalibur weaponizes artistic creation—a clash that forced Ruro to innovate beyond conventional warfare.

References to his past remain vague, anchored only to allusions of a “varied life,” with no expanded lore in alternate media.
