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.
Hey! Luna!
Ah, Luna.
Stop, Luna !
Reste derrière le rideau !
हे! लूना!
Luna! Non uscire dal velo!
