It definitely feels like the author pieced together different panels as they were going along (as they mention in the afterword), as Misaki's underwear on both the top and bottom seems to randomly appear and disappear. Page 15 is the funniest where the same page shows two opposite configurations at thee same time.
I love Misaki the most gorgeous and precious and adorable member of Arius squad who deserves the whole world and I would do everything in my power to make her smile. I'm okay with the rough TL and disjointed doujin just because she's so cute.
