Despite literal years of Zeff badgering Sanji and trying to get him to give up being the sous-chef at the Baratie and go on his own adventures already, Sanji refuses. He owes Zeff his life, his past and future, everything he can give the old man—he's not leaving. His occasional excursions elsewhere and back are just temporary ('internships,' Zeff calls them), and he always eventually returns home. This time Sanji visits Tottoland, excited to learn from the culinary envy of the world, but he encounters a lot more trouble there than he expects in Charlotte Katakuri.
