Cyno is a curt, stoic and generally emotionless man with a ruthlessness and vicious approach to his duty as a matra that make him intimidating and unapproachable. Despite his seriousness in academics and work-related matters, he is fairly relaxed outside his duties. He tells jokes to help people relax around him, though they're generally unfunny and his long-winded attempts to explain them even more so. He has tan skin, red-orange eyes, and medium-length gray hair.
