Number 1: Sketch Stripe Show

 * Sono 1: Sukecchi Shima Shō (その1 スケッチしまショー)

Yui, Tsumugi, and Ritsu attempt to sketch things from their memory alone. First they draw a raccoon, then Yui's sister, Ui. Finally, they draw the panties Mio wore during the school festival. Embarassed, Mio shouts that all their drawings are wrong.

Number 2: Presents

 * Sono 2: Purezento (その2 プレゼント)

Mio receives many presents from her fan club. Yui, Tsumugi, and Ritsu open them for her. They all turn out to contain panties, much to Mio's shock.

Number 3: Fan Club

 * Sono 3: Fan Kurabu (その3 ファンクラブ)

Ritsu shows the others a membership card for Mio's fan club. The card shows a picture of Mio's panties. Mortified, Mio hits Ritsu and accuses her of creating the card herself.
