夏休みに入り、トロピカる部は夏合宿をすることに。場所は、まなつの生まれ育った故郷・南乃島。合宿のしおりを作り、楽しみで待ちきれない気持ちで出発の朝を迎えるが、そこにゼンゼンヤラネーダが現れ...。
Summer vacation from tomorrow. Manatsu's words, "I want to have a training camp," led the Tropical Club to hold a training camp in Manatsu's hometown, Minaminoshima.
While everyone is making bookmarks for the training camp and planning the schedule, Manatsu will showcase a lot of recommendations from Minami Nojima, such as caves where treasures are hidden, secret beaches, and island festivals.
Manatsu y las demás comienzan las vacaciones en la escuela, así que deciden irse de viaje a Minamino, la isla donde creció nuestra protagonista.
Chegou a época do recesso de verão! As meninas do Clube Tropical decidem fazer um acampamento de verão para a Ilha Minamino, a terra natal de Manatsu.
