Thank you for translating!
Personally, I had mixed feelings with the shift of the story starting from volume 14. I loved the 1st part although I do think it sometimes started to feel stale, but the gun fights and strategies were really well done. The 2nd part, feels less about gun fights and more desperate survival.
I do wished there were more about Kasuna being Teruterubouzu antics, but instead it was survival and warfare.
At least a lot of questions were answered.
Lol Kanta at the end, he really is the demon of the desert.
