Isaku is kidnapped by members of the Kodan-gumi, and Keiya has to save her. Although Isaku's summer break comes to an end, Keiya tries to make up for lost time with an in-house summer vacation getaway.
I have a watermelon, fireworks,
and shaved ice, too.
لديّ بطّيخة وألعاب ناريّة وثلج مبشور أيضاً
Wir haben eine Wassermelone,
Feuerwerk und Eis.
Tengo sandía,
fuegos artificiales y granizado.
Abbiamo anche un'anguria,
 la granita e i fuochi d'artificio!
Я подготовил арбуз,
фейерверки и колотый лёд.
