Hearing about the upcoming Noble Party, Haruka decides to try her hand at making her own dress under Miss Shamour's instruction. While managing to come up with a design, Haruka struggles with the sewing aspect. When her grades start slipping as a result, Haruka is told by Minami to stop making the dress and focus on her studies, but Haruka instead decides to try and work extra hard to accomplish both. Overworking herself enough as it is, Haruka feels compelled to remake her dress from scratch after Puff spills some tea on it, prompting worry from Kirara, who feels she can't do it alone with the time she has left. After hearing from Minami about how Haruka is working hard to accomplish her dream with her own power, Kirara tries not to involve Haruka when Lock appears with an Oven Zetsuborg. However, Haruka steps in anyway, stating that despite how tired she is, she is determined to work hard for the sake of her friends. After defeating the Zetsuborg, Haruka finally finishes her dress, thanking Kirara for worrying about her.
もうすぐはるかにとってはじめてのノーブルパーティー！
このパーティー、生徒はみんな正装するのが決まりなの。
女の子はドレスを着るんだって！！
じぶんでつくったドレスを着ていきたい！
そう思ったはるかは、ミス・シャムールを呼びだして、
ドレスづくりのレッスンスタート！！
ドレスのデザインを描いて、生地を切って、
いよいよミシンでドレスをぬいはじめる。
でも、はじめて使うミシンは、むずかしくて上手にできない・・・。
はるかは、毎日夜おそくまで起きて、一生けんめいがんばるの。
どんなドレスができあがるのかな・・・！？
