These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
OOC Is Serious Business - Depends on how much you know of the story. In their background story, Shakunage tries killing Suzuran out of bloodlust, which is what leads her and Shion to join the Gekka Battalion. However, if you play as them and meet up with him during the third boss fight, he seems surprised that they're on the opposing side, and apologizes them when he dies. Based on the True Ending, Shakunage's calmer, more caring side is his real face, so his moment of bloodlust was OOC.
