Kurotsuru

Dr. Kurotsuru, also named "Dr. Black Beard" based on the same name on the lapel of his coat, is a doctor who appeared in Ace's mini-story.

Appearance
Dr. Kurotsuru is a round man with relatively thin limbs. Like Marshall D. Teach, he has fluffy black hair with the top tucked in by a bandana. He also has a goatee. The doctor wears round glasses, a white a-shirt with a cross on the front, striped-patterned pants, white shoes, a doctor's coat with the name "Dr. Black Beard" on the left side, a medical cross on each side of the collar, and carries a pen in the right breast pocket of the coat.

History
Ace mistook him for the real Blackbeard and kicked him to the ground, much to the fury of everyone else around them. When Ace realized his mistake, he was kicked into the river by the angry Dr. Kurotsuru, an angry cook (whom Ace did not pay for his meal from earlier), and other spectators who were furious at Ace's attack.
