Muv-Luv 8
I appreciate how Yui's final push over the hill of tsun to the fields of dere was actually given a decent reason rather than simply the "lol they played on da beach and Yuuya was a gentleman so they coo now" that I expected.
And this is liable to be written off as just a coincidence and/or lazy background art, but I believe
the meeting in the hall of the Soviet base from this episode was meant to be a reference to
their very first face-to-face from the end of episode 3 as a way of contrasting then and now.
Whether this bookend is just meant to indicate the conclusion of Yuuya's training under Yui or (more worryingly) the end of one of their stories, I can't say. The former fits, but this is
Muv-Luv so I am going to prepare my anus for absolute devastation.
