@infidel28 which one? Akutagawa or Atsushi? Or, maybe both?
Also, wasn't the tone of the story had always been like this? Yes, it's edgy but it's not unbearable.
Even though Juliet's screen time in the vol 13 was a bit short, she still completely managed to prove herself again as a badass character.
Especially that last move of hers... I'm still getting chills when I remember it.
