As usual, Kinugawa and Yufuin are walking to Binan High School together as friends. But after a stop at the convenience store, Yufuin suddenly gets angry at Kinugawa and yells at him. A rift forms between the two, and soon a panic develops over them potentially leaving the Defense Club. Yumoto works blindly to try to get the two to make up, but Naruko and Zaou rebuke him for it. Will Yufuin and Kinugawa ever make up?!
No, no. It's my fault for getting 
potato chips all over your bed.
Nein, nein. Ich bin schuld, weil ich Chips
auf deinem ganzen Bett verteilt hab.
No, no. Es mi culpa por dejar 
restos de papas por toda tu cama.
No, no. Es mi culpa por dejar 
restos de patatas por toda tu cama.
Non, c’est moi,
j’ai mis des chips sur ton lit.
No, no, è stata colpa mia per aver
 sparso patatine fritte su tutto il tuo letto.
Não, não. É minha culpa por ter
 derrubado batata chips na sua cama.
