S1·E5 In danger!? Mami's secret

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.
