"The Two Fight!? It All Started Over Squid!" (二人がケンカ!?始まりはイカ!"Futari ga Kenka!? Hajimari wa Ika!" ) 

Haneru and Kanon get into a fight with each other over which of their snacks is better, which somehow leads to Mizuki and Yuzuru picking sides before they can settle it normally. Haneru and Kanon try to apologise to each other, but an interruption by Yuji just leads to the situation becoming worse. As both feel that they want to make up but are too stubborn to apologize themselves, it is eventually their desire to dance together that helps them get over their feud.
