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.

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.

Creamy Crepes and Parthenon Productions behaving the proverb »Great minds think alike« on a beautiful day sets the stage for Toshio and Shingo's social missteps to get them in hot water with Yuu and Megumi. While Shingo is able to gulp down a lot of humble pie for not watching his words to Megumi, seeing past Toshio's immature human fallibility is the last thing on Yuu's mind especially when Toshio derails her concentration when jumping across a river. Be it to teach Yuu a lesson in appreciating her assets or to simply have fun, an apparition decides to envelop the sextet inside her mystic pseudo-reality of a spatially-enclosed forest with an empty house as the nexus. Yuu is shocked to find that the apparition has housed herself within Toshio to wield him as an escape vehicle only for Yuu to foil the attempted abduction; after Hayato explains her the prologue behind the apparition Andrea that abducts children that look like her late paramour, Yuu realizes the danger Toshio is in and rushes to the rescue. The ultimate silver lining during this interactive ghost story is that Andrea is merely misguided and has not a mean bone in her body although she does try her best to inhibit Yuu's proximity while she makes her escape with Toshio; all Creamy Mami had to do is to acknowledge how important Toshio is to her and understand Andrea's feelings.
