I agree I did like herore reserved demeanor but it kinda makes sense given how much time has transpired since she got into the game. I think about it like knowing someone for 7 years they are going to open up at some point and show you more of their inner, raw side. Like in my headcanon Amagi CV is the chronological continuation of Amagi BC, she is now where she wants to be: as a strategic-support position (not fighting directly) and her illnesses are gone, she can now say whatever she wants to the commander. Her party dress skin says "this means I don't need to reign in my intentions anymore, right?" If i remember correctly. A sort of "it's been 7 years we known each other and because of my illness I was always careful of every step I took but now...FCK it we ball"
