He’s a cold-hearted man who doesn’t have a care in the world, but loves his siblings very much. He wears a scarf to cover up his very sharp teeth because he is very insecure about them. 

Katakuri is always on his feet, no matter what. He's very serious, and hates jokes and surprises. His favorite food is donuts, but eats them in private because of his teeth under his scarf. 

In this world, he’s wanted for a lot of money. Like a 10,000 bounty put on his head just because of his actions.
