There's so much I love about this that I don't even know where to begin. Crack is all jolly good, but seeing the darker side of the war/their relationship on the battlefield is always so heartbreaking and thrilling at the same time.

I love how you wrote their dialogue and meaningless (and sometimes not so meaningless) banter. Also using bickering as a way to ease the tension around them is such a Gintoki thing to do. And that wink was by far my favorite part.

And even though we only got a glimpse of Takasugi so far, I really like your characterization of him.

Really looking forward to chapters 2 and 3!
