The third Idol Time Grand Prix is coming up, Yui, Nino, Miichiru, and Shuka all work their hardest to prepare for it. However, Shuka asked Mimiko Jigoku to help her train until she is 100% perfect for the grand prix. Shuka had almost been disqualified due to her lateness. But luckily, she arrived safely and won the third idol time grand prix.
迎えた第3回アイドルタイムグランプリ当日。パパラ宿のナンバーワンアイドルになると高らかに宣言したしゅうかはミミ子を味方につけ、地獄のレッスンを積み重ねていた。実力で優位に立つしゅうかに負けじとゆい・にの・ミーチルも精一杯練習する。果たしてゆい達はしゅうかに勝って優勝することができるのだろうか。
