Kakage's reaction was nothing short of hilarious. Too bad she's not in seifuku to play on the JK meme.

Added to the pool considering in the latest arc of the game, which seems a high school AU, she's a nurse.
From the description, it sounds like the crew escaped from the True King to an island with a very Japan-esque school; gakuran and all. Then proceed to do undercover work to find info on the primal beast. So no it's not AU, but actually part of the main storyline.
