Magical Angel Creamy Mami

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.

Undaunted by the spanking received from Natsume last night, Yuu steals out of the house early in the morning in order to test her powers as Creamy Mami; while Yuu admires herself as Creamy Mami, Nega and Posi get into a divergent concourse over who is to blame for Yuu successfully sneaking away when Mami decides to drop in for a visit to see if Tetsuo and Natsume can recognize her before flirting with Toshio as she leaves. Meanwhile, Shingo Tachibana is dismayed to have it explained that Megumi Ayase and her manager Hayato Kidokoro are stuck in traffic along with finding that he has to resolve all the office politics caused by such a development until he encounters Mami walking around; a whirlwind of customization and instruction later, Creamy Mami is enjoined for a song whose lyrics the host withholds from her. Even if Creamy Mami successfully improvises a song and escapes the stampede of her newfound fans, Yuu is still stuck with a lengthy home commute whose resolution ultimately requires Toshio as a deus ex machina -- after Creamy Mami admonishes Toshio to behave dignity and respect unto Yuu.

Toshio's efforts to temper Midori's expectations of spending time with Yuu obfuscate the fact that Yuu herself is grappling with the disadvantages of being Creamy Mami -- the greatest of which is the narcissistic and fanatical Shingo Tachibana hell-bent on making Mami a star with his company as he orders his staff to find her. The panic Yuu is driven into at the sight of Toshio explaining Shingo his recent encounters with Creamy Mami while Midori tries to steal lustful glances at her illustrates the immense contention that Yuu undergoes as she tries to keep her double life as Creamy Mami a secret although Tetsuo and Natsume are picking up some piecemeal clues; nevertheless, Yuu unwisely decides to »debut« before Toshio so that she can explain things and nudge him toward the rest of his life but is shocked to find that Shingo has other ideas and is not taking no for an answer. Facing the backdrop of Shingo and Megumi ultimately having made the choice for her, Creamy Mami begins her career at Parthenon Productions in earnest.

The hysterical frenzy over Creamy Mami's debut song evenly divided between people buying the album and converging on the upcoming concert obfuscates that the magical idol is actually Yuu Morisawa effecting the mirage of being infirm -- although she almost blows it at the mention of her favorite dish. Yuu finds that the successful concert at Parthenon Productions as Creamy Mami does her no good against Natsume's zeal to impart her maternal perspective on her subterfuge or the impromptu test for sleeping in class; if those problems are not enough, Toshio's teasing and a collision into Midori costs Yuu her compact right when she is going to need it the most. Yuu's frantic search for the compact gets a big boost from Toshio explaining that Midori at the amusement park has it; while she successfully conquers the high-stakes aerial adventure necessary for its retrieval, Yuu ultimately ends up igniting Megumi's vendetta of Creamy Mami.

While watching Hayato Kidokoro tie himself in knots answering the telephones, Shingo revels in the prospect of Parthenon Productions flourishing and thriving when Nega admonishes against keeping Natsume and Tetsuo waiting for too long at home prior to reminding her about the reporters; it is the search for a place to cancel her henshin before beginning the home commute that Megumi obtains enough vicarious data to conclude that Yuu Morisawa and Creamy Mami are one and the same prior to taking revenge by searching for a way to prove her hypothesis. While Midori has gathered the courage to convey his affection for her the next day, he is crestfallen to have Yuu race right by him oblivious to nearly bowling over Toshio on her way to the Studio where following Posi's suggestion to kill time exploring lands Yuu right in Megumi's clutches whose plan becomes more likely to succeed by the minute along with the prospect of Megumi blowing the whistle on Creamy Mami. The ironic deus ex machina that enables Yuu to turn the tables comes in the form of Toshio and Midori finding themselves the vendetta of an unreasonable and persistent sentry whose chase ends where Yuu is being held; thanks to Posi and Nega helping with the back-end logistics, Yuu successfully extinguishes Megumi's hypothesis.

While Hayato and Shingo compare notes with Megumi about whether Creamy Mami will be punctual for an advertisement filming in a wilderness area reputed to have a black stag that has been visiting unto the locals bad luck, Yuu daydreams about being on a date with Toshio cured of his Creamy Mami addiction but causes a misunderstanding on the train when she speculates out loud Toshio and Midori's hidden motives for the outing; during the bus ride from the train station, Nega and Posi compare notes about the legend describing a magical stag that once resided on the Feather Star along with the pros and cons of emancipating the mystical ungulate from its subterranean prison. The astonished adoration of the black stag quickly gives way to it being time for Yuu to do her thing as Creamy Mami. The black stag's risky shortcut whose zenith is being trapped on a high rock ledge has the ironic silver lining of ultimately being the commercial Creamy Mami is to have done originally; now his former golden normal-sized self, the stag explains Mami his prologue and leaves behind the capability to manipulate the environment as he returns to the Feather Star.
