This is why Oda chooses
now to have Katakuri remove his scarf. He is both literally and metaphorically shedding the facade and embracing his actual identity. And what do we find underneath his Scarf?
On the back of his jacket, the name "Charlotte." The symbolic meaning behind the word "Charlotte" on Katakuri's back should be pretty obvious, but what's a bit more subtle is about how Katakuri carries his family name

underlying motivation for Katakuri's Facade (the scarf), and thus how seriously he values the well-being of his family, is the conviction that he has for keeping his family safe. Hence, the
