A series of missing children incidents has occurred among the merchant families in town, but each of the children has returned in a matter of days. And yet, the client's child has been missing for a month. Kyousuke takes on the case in place of Takuboku, who's health is poor, and drags Sakutarou and Kodou into the investigation with him. While they're doing that, the client's child suddenly returns. Is this case closed? Meanwhile, the incidents involving letters of accusation thought to be finished with Tamaki's death start up again. Takuboku sets out to discover the true identity of Accuser X.
