I see Utsuho alive and well in the end.
In the middle, there was some huge angsting and explosions going around, and suddenly Utsuho grits his teeth and hugs Atsuma, which made me raise an eyebrow because it was about time. :D Everyone moved on pretty well in the end, and in the final scene, Utusho and Atsuma stares over the hills together.
In other words, I haven't a single clue what was going on since I don't know Japanese, so I thought I'd do myself a nice favor by staring at the pretty pictures and oogling at the bromance.
If anyone could summarize a good account on the final volume, it would be much appreciated!
