His typical attire consists of a dark outfit that complements his role as an executioner, allowing him to blend into shadows and maintain a threatening presence. His sharp eyes and stoic expression emphasize his professionalism and combat expertise.

Oboro is a pragmatic and loyal executioner who works directly under the Game Master’s orders, showing no hesitation in eliminating his targets. He operates with a cold and logical demeanor, dismissing pleas for mercy by explaining that the rules of Darwin’s Game leave no room for sentimentality. He rationalizes his actions by emphasizing survival, stating that his own life is constantly on the line, and he must use his abilities to ensure his survival.

Despite his ruthless nature, Oboro demonstrates a refined sense of combat and prefers facing opponents he deems worthy. He expresses disdain for adversaries he considers “classless” or unskilled, urging the Game Master to provide him with more challenging and respectable enemies.
