Yui Nagomi and her trusted fairy companion Kome-Kome wake up to the sound of a marching band. Yui looks outside the window and there's a parade of...ROBOTS!?! They are promoting the newly built amusement park called “Dreamia” that is themed after Kid's Lunch meals and operated by the legendary and reclusive scientist Cait Sith. Yui and her friends decide to attend the newly built park (with parent's permission), but there's a catch, only children are allowed in the park! Recognizing something strange about Dreamia, the girls' mentor, Rosemary, becomes worried and tries to enter the park but is apprehended by robot guards. The girls decide to rescue Rosemary and enter the behind-the-scenes areas of the theme park. What secrets lie beyond the Kid's Lunch themed exterior?
