Tooru Muhyo is said to be the youngest executor who graduated from the Magical Law School. Muhyo paired up with Roji and the two formed their own business of exorcising ghosts. He seems to try to show no signs of caring for his assistant, Roji, but it immediately becomes evident that he does during dangerous situations, or when one of Muhyo's friends or acquaintances points it out. He is often rude to other people and keeps a stern face, but deep down, he has a strong sense of justice. He is extremely powerful, being able to perform a judgment that normally requires four top-notch executors by himself.
