Anime Volume. The episode shows three short clips of Yui Hirasawa's imagination as she thinks about her fellow club members Tsumugi Kotobuki, Mio Akiyama and Ritsu Tainaka.

Number 1: Mugi-chan

 * Sono 1: Mugi-chan (その1 ムギちゃん)

Yui notices that Tsumugi's eyebrows look like pickled radishes and she wonders how they move. Tsumugi distracts her by pointing at something behind Yui, causing Yui to miss Tsumugi moving her eyebrows.

Number 2: Mio-chan

 * Sono 2: Mio-chan (その2 みおちゃん)

Yui wonders what Mio's forehead looks like. After two failed attempts to see it, Mio agrees to show her, but in her excitement to see it, Yui accidentally butts heads with Mio, preventing her from seeing it.

Number 3: Ricchan

 * Sono 3: Ricchan (その3 りっちゃん)

Yui wonders how Ritsu would behave if she were Tsumugi, Mio, or herself. Embarrassed at the thought, Ritsu scolds her.
