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?!
That's very convenient...

Das ist sehr praktisch …

Qué conveniente... Es decir, 
como si no hubiera pasado nada.
Qué conveniente... como 
si no hubiera pasado nada.
C’est de l’opportunisme, là.
Ou de la chance dans le malheur.
Questo è stato davvero conveniente. 
Una fortuna nella sfortuna.
Aquilo foi muito conveniente... 
Quero dizer, agora tem um novo forro.
