[Machine Translation] The Karasu Tengu clan was in charge of all the duties at the Yokai Inquisitor's office. Tobikuro was the head of the family and the right hand man of the magistrate, Lord Tsukiyo. One day, Tobikuro brought his twin sons, Ukyo and Sakyo, to the office. The twins would be assigned to a mission in the future, so Tobikuro decided to let them observe while they were still young. The magistrate's office is very busy, but behind the scenes, a terrible incident is going on involving Tsuyumi, Lord Tsukiyo's nephew, and Yasuke, the caretaker of the children of monsters. This is the seventh installment of the very popular series.
