Ash and friends (this time accompanied by newcomer Dawn) arrive at an idyllic village on their way to their next Pokemon contest, where chaos will soon erupt with the prophecy of two Pokemon Gods (Dialga and Palkia) and the arrival of a mysterious, seemingly deadly Pokemon named Darkrai, which has the power to distort space and time.

The protagonist falls in love with his junior in a college club, and struggles daily to be noticed by her. However, she is naïve and unsophisticated and is completely indifferent to him. This comical love fantasy depicts absurd and interesting daily happenings in the city of Kyoto.
