Shingo Tachibana completing his work commute excited about the debut of Creamy Mami's new song quickly gives way to neurotic despair upon having it explained that the star of the show is stranded at Atarajima with Hayato. Shingo is naturally none too pleased at the news; a caustic castigation later, Hayato finds himself led through a multi-modal tour de France across Japan that starts with a flight to Osaka and a ride on the Shinkansen that ends up at a dead end in Mishima right when Megumi successfully placates Shingo into eating lunch. Driving into the savage vendetta of a neanderthal trucker that forces them off the highway and onto a wooden bridge whose collapse gives way to a wild voyage on a passenger ferry at Hakone has the ironic silver lining of the journey ultimately getting a big shot in the arm from some kids on a field trip; a couple of well-timed henshins and Toshio performing his contingency messenger role along with a timely thunderstorm later, Creamy Mami stylishly arrives at the concert fashionably late thanks to Megumi.
Per un errore di Kidokoro, Creamy si trova nel giorno sbagliato sul luogo delle riprese, dall'altra parte del Giappone. Devono fare così l'impossibile per rientrare a Tokyo dove alle 18 la star è attesa per un concerto allo stadio.
マミの新曲キャンペーンコンサートが開催される。しかし木所がCF撮りの日を間違え、マミを新島へ連れて行ってしまった。急いで戻ろうとしたが、乗ってきたセスナは帰ってしまう。様々な手段をつくす二人。なんとか東京に戻れたマミを、めぐみの発案でDJブースに乗せ会場までヘリで空輸した…。
