The story begins with our heroine Yuu Morisawa watching the Feather Star descend for a landing oblivious to the hefty workload at the crepe shop that her parents Natsume and Tetsuo are desperately trying to resolve on their own; a clumsy stumble into her childhood friends Toshio Ootomo and Midori Kisaragi later, the panicked Yuu votes with her feet using Tetsuo's scooter into a frenzied pursuit sequence whose zenith is four police cars and a helicopter along with Toshio on a bike. Oblivious to the chaos that she has caused with her mad dash through town, Yuu is enthralled with the Feather Star as it comes in for a landing; upon learning that she can see the Feather Star, the two alien cats Posi and Nega draw Yuu aboard where there is a dysphoric fantasy dream sequence that gives way to an encounter with the grateful alien Pino-Pino. Having some family government imparted at the breech upon arriving home sets the stage for the ultimate silver lining of Yuu finding that Natsume and Tetsuo are not hostile to housing the two alien felines who later lead her through utilizing her new-found magical powers; after some cryptic and perplexing trial and error, Yuu successfully initiates her first henshin into Creamy Mami.
