At first glance, Ian seems like an easygoing, cheerful young man who isn't afraid to speak his mind even when he was just a low-ranked Rook. He has the audacity to be disrespectful towards his superiors, such as addressing the senior Loco "-chan" despite her age gap and talking back to Halloween, one of the highest-ranked Knights. However, Ian's friendly demeanor belies his fierce fighting spirit on the battlefield. When driven by determination, he becomes relentless in his pursuit, whether it's for a fight he enjoys or to eliminate an enemy sworn to him. His tenacity often leads him to go against orders, and as a result, Ian is always mentally prepared for death penalty.
