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?!
Didn't we have the most fun in history 
together over summer vacation?
In den Sommerferien hatten wir
doch super viel Spaß zusammen, oder?
¿No nos divertimos bastante 
en las vacaciones de verano?
¿No nos divertimos lo suficiente
en las vacaciones de verano?
Cet été, on n’a jamais passé
autant de temps ensemble !
Non abbiamo forse raggiunto il massimo livello 
storico di divertimento nelle vacanze estive?
Não tivemos a maior diversão da história
 juntos nessas férias de verão?
