Kurotsuru

Doctor Blackbeard is a doctor who appeared in Ace's mini-story. Ace mistook him for the pirate, Blackbeard and kicked him to the ground, much to the fury of everyone else around them. When Ace saw his mistake, he was kicked into the river by the angry Doctor Blackbeard, an angry cook (who Ace did not pay for his meal to earlier), and other spectators who were furious at Ace's attack.
