Cyno is a curt, stoic and generally emotionless young man with a ruthlessness and vicious approach to his duty as a matra that make him intimidating and unapproachable. Despite his intimidating demeanor, Cyno has a soft spot for humor and enjoys cracking jokes to lighten the mood in certain situations. However, his sense of humor is often misunderstood by others, as his jokes tend to be too long or unfunny, requiring him to explain them in detail for others to understand.
