Megumi is a very outwardly stoic, aloof, and calculating individual. He usually has a neutral facial expression that he rarely changes and appears to take every situation seriously. He has a simmering temper like a ticking time bomb when it comes to things that agitate him, and this temper of his easily sparks annoyance in his demeanor. However distant he may seem, he has a heart of gold when it comes to his familiars and is willing to do everything in his power to ensure their safety.
