Chengxi Huang recently gave a speech wherein he talked about his time at CANDYBOX and mentioned he did KA for Silver Spoon #16.

I'm not sure how many of these cuts are his, I think the last four but it could possibly be all of them, we know for certain the last one belongs to him because he pointed out how he drew China (his home country) on the camouflage of this guy's shirt https://imgur.com/a/CLlNFnp
