...they totally learned that they'd been murdering dudes that could've been cured in the last chapter, and everyone's just 'yay! cute family reconciliation!'
Also, what makes this a shared universe with GATE? I didn't see anything.
As soon as I saw the title, I recalled Itami and pal singing that during their first recon trip, the one to coda village that would continue to the burnt elven village in the forest..
And end with returning back to base with refugees and three girls for his harem.
It was a cute little funny story, Itami has good taste. All though I imagine it would be something a little different in his world hehe, like not just being hastly made anime tie-in manga, but it was still good for what it is.
