Dr.Kureha

A doctor over 130 years old and Chopper's second mentor, affectionately known as "Doctorine." Originally from the Drum Kingdom, aged 139 to 141 years. Her birthday is September 8th, and she stands 188 cm tall. A Virgo with blood type S. Her favorite foods are alcohol and pickled plums.

Known as a "Master of Medicine," she demands enormous fees from her patients, earning her the fearful nickname "Witch" among the people. She used to live in a large tree on the outskirts of Gasta Town, but moved to Drum Castle after Wapol fled. Cheerful and stylish, she doesn't show her age and can kick as well as Sanji. It's forbidden to call her "old lady" or "granny" in her presence, as she gets grumpy and throws knives in a rage. She has a rough manner and a foul mouth but is also very loyal. Her laugh sounds like "Hee-hee-hee," and her catchphrases are "Feeling happy?" and "The secret to youth, huh?" She refers to illness as "happy," because it makes one appreciate the happiness of being healthy. Her secret to youth is staying happy. She seems to know something about the "Will of D."

The sole survivor who escaped Wapol's doctor hunt. Eight years ago, she was entrusted with Chopper by Hiluluk, who was close to death, and she rigorously trained him in medicine as if he were her own son.

She climbed Drum Rock and treated Luffy and his crew when they reached Drum Castle. When Chopper joined the Straw Hat Pirates, she chased them off with a barrage of weapons, seemingly disliking sentimentality, but secretly packed a backpack with medical tools on the sled they used to descend the mountain, tearfully watching them recreate Hiluluk's "cherry blossoms."

In the New World saga, she has established a medical center called "Isshi-100." During the World Conference saga, she accompanies Dalton as a ship doctor.
