This went from only the attack heroine in the escort party being the crazy one to the attack heroine, the assassin, and the princess all being crazy. Going to assume the healer and the princess's bodyguard are normal until proven otherwise. Good luck to the MC, he's going to need it. I did like Cain's character development--dropping the family name and the decorative B-rank to self-demote to D-rank and start fresh was not what I expected him to do.
