Summary
''The Yo-kai "Shutendoji" and his subordinate "Douketsu" are looking for a being called the "princess." The purpose of this duo is to restore the original power of the princess that has currently been lost. It is for that purpose they are collecting the five "Youseiken" they need, and they have their eyes set on the one that Touma currently owns. Meanwhile, Natsume and the others at the Yo-kai Detective Agency are browsing Usuranura, looking for mystery cases. However, the only thing out of the ordinary by the three of them, is the dull expression Keisuke is showing. Keisuke is normally scared to death about unnatural phenomenon these days. This time, when they try to slip out of this mysterious matter at the office they'd rather not get sucked into, Douketsu appears and takes them off.''
