Yuuya runs across a girl fighting monsters in the Darkest Regions. She calls herself Luna. They begin spending their days training together, sweating side by side. Back at Ousei Academy, the off-campus study trip begins at a site deep in the mountains.
This time I've spent with you is my treasure.
.الوقت الذي قضيته معه هو كنزي
Die Zeit mit dir war sehr wertvoll für mich.
El tiempo que he pasado contigo
es mi mayor tesoro.
El tiempo que he pasado contigo
es mi mayor tesoro.
Je chéris le temps
que j’ai passé avec toi.
तुम्हारे साथ बिताया गया यह समय, 
मेरे लिए अनमोल ख़जाना है।
Il tempo che ho trascorso con te, Yuya,
O tempo que passei com
você é meu tesouro.
Время, проведённое с тобой, 
будет моим сокровищем.
