クリィミーマミのおかげで優は毎日大忙し。授業中に居眠りをして居残りテストをうけることになる。落ち込む優に俊夫は勉強を教える約束をするが、トップテンに出演するマミを見たいからと断わってしまう。俊夫の為と1度は断わったトップテン出演を決心する優。だが変身しようとした時、コンパクトを落としたことに気がつく。
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.
