The film opens at a café in the human world. The numerous café patrons argue among themselves as a strange green mist swirls around their feet. In the corner booth, three girls in hoods sing and absorb the green mist into the red gems on their necklaces. The purple-haired girl Aria Blaze grumbles that she's "tired of fast food" and needs a meal. The orange-haired girl Adagio Dazzle laments that the energy in "this world" isn't the same as that in Equestria.

As the blue-haired girl Sonata Dusk joins the conversation and gets into a light argument with Aria, Adagio notices an explosion of light in the distance. She races out of the café and watches the magical rainbow energy burst into the sky, grinning evilly when she realizes what it is. She explains to Aria and Sonata that Equestrian magic has found its way into the human world. you are the ninja that everyone was talking about and you were hiding in the alley and you saw the dazzlings.
