Muhyo and Roji are finally back in town, but business isn't so good. Worse, they seem to have a major new competitor: Goryou Daranimaru, of the Goryou Bureau of Supernatural Investigation. He was an upperclassman of Muhyo at Magical Law School and, while not on Muhyo's power level, is nonetheless a capable enough enforcer that, with his trusty judge assistant Ebisu, he can tackle spirits plenty well and has built a nationwide chain of bureaus. Roji and Nana find that out themselves when Goryou and Ebisu show up when Nana goes to check on two friends who had been playing Kokkuri-san (basically Ouija) and accidentally summoned a real spirit. But Goryou's pricing and business methods are ruthless, and he further seeks to take over Muhyo's own bureau. Meanwhile, Enchu is having problems with fake forbidden texts.
