These are the tales of a certain high school student, who is visiting a certain cave... a certain young couple who are out to see a fireworks show... and of a young man who is very afraid of thunder...
And thus, the Kaminaga Expedition Force 
set out to explore the uncharted cave.
وهكذا، شرعت قوّة كاميناغا الاستكشافيّة 
.في استكشاف الكهف المجهول
Und so brach die Kaminaga-Expeditionstruppe
auf in die unerforschte Höhle.
¡El equipo de expedición de Kaminaga
se pone a explorar la caverna!
El equipo de expedición de Kaminaga
se pone a explorar la caverna.
Notre bataillon s’enfonce
dans la grotte inconnue.
E então a expedição do Kaminaga foi 
explorar uma caverna desconhecida.
