Hime is excited for the school culture festival, which would be her first, and tries to help out as much as possible, but struggles to find something she can help out with. Luckily, the student council president gets Hime to help him put up posters around the school, learning the festival is all about everyone working together. She later gets by everyone to help make the front gate look appealing. The next day, as the festival gets underway, Namakeruda appears and targets the student council president to create a Festival Saiark. As Hime strives to protect the gate that everyone made together, she awakens her Innocent Form, using its power to help defeat the Saiark.
明日の文化祭に向けてみんな準備に大忙し。ひめは大事なゲート作りでセンスを発揮して、すごく素敵な仕上がりになったよ！ そこへ文化祭をメチャクチャにしようと襲ってきたナマケルダ。プリンセスがひとりで立ち向かう！
