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.
I taught Luna a lot, but she taught me a lot, too.

Luna y yo aprendimos bastante,

Luna e, claro, eu também
aprendemos muita coisa
Мы с Луной обучали друг друга
