Duke Hitsugisukan is a sheep mink and the former ruler of the Mokomo Dukedom before Inuarashi and Nekomamushi.


Hitsugisukan is a large sheep mink with white wool and black skin. He has curved horns, a walrus mustache, and fluffy beard. He wears a dark colored king’s robe and a crown.


Hitsugisukan is very knowledgeable and respectful of traditions of the Mokomo Dukedom.

He also seemed to be very caring for his subjects, as he cried upon learning that Inuarashi and Nekomamushi were alive and safe.


Inuarashi and Nekomamushi

Hitsugisukan cares greatly for Inuarashi and Nekomamushi, to the point of teaching them the past of the Kozuki Family and the Mink Tribe, and showing them the dukedom’s treasured and secret Road Poneglyph. Even after leaving the country, a letter of recommendation from Nekomamushi and Inuarashi was enough to grant the Roger Pirates access to the Whale Tree.

Abilities and Powers

When he was the ruler of Mokomo Dukedom, Hitsugisukan had authority over its citizens, landmarks, and artifacts. He was also in charge of approving requests of visitors to the dukedom.

As a mink, he is a natural born fighter, able to use Electro, and transform to his Sulong form under the full moon.


Around 30 years ago, Hitsugisukan showed the Road Poneglyph hidden in the Whale Tree to Inuarashi and Nekomamushi, and explained to them the Mink Tribe’s connection to the Kozuki Family, inspiring them to set sail toward Wano Country.

When the Roger Pirates visited Zou, Hitsugisukan received a letter of introduction from Nekomamushi and Inuarashi, making Hitsugisukan pleased to know that both of them were alive. He then granted the Roger Pirates access to the Road Poneglyph in the Whale Tree.
