great writeup! agreed with everyone that the end was truly bad - it has major 1-5/E1-5 issues. i didn't enjoy kazuma in gaa2 as much as you but i do agree that his character felt consistent and well-written - it's hard watching someone who seemed as pure and dogged as AA3 mia reveal such a twisted hidden side.
yet all azuarc of all sorts are more or less capricious and unreliable - they live in the varying outer weather, and they inhale its fickleness
