Cora-san - OP
Donquixote Rosinante, also known by his codename Corazon, is a character from One Piece. SPOILERS ahead!
He is the younger brother of the Warlord Doflamingo, and served as kind of a father figure to Trafalgar Law after the Flevance massacre, helping him find a cure for his mortal disease. He's also the main reason why Law has his devil fruit powers. He was called "Cora-san" in an affectionate manner by young Law after he befriends him.
