Musashi

Musashi is a youthful man who keeps his black hair bound in a topknot. His outfit pairs a blue top with a red vest, worn over checkered trousers patterned in white and gold.

Few details of Musashi's character are established, but his defining trait is unwavering loyalty to Kardia. He throws himself into his leader's bid for vengeance against the Straw Hats and carries out reconnaissance on them without hesitation or complaint.

As a samurai, Musashi commands genuine fighting skill and wields cutting techniques with his katana, a blade set in a white hilt and a white sheath decorated with a blue flame motif. Even so, he was overmatched by Zoro and went down in short order. His named techniques are Musou Kiri, a forceful slashing strike, and Hissatsu Musou Dogeza Kiri, a stronger version whose full effect was never seen because Zoro cut him down mid-attack. Born in Wano Country, Musashi at some point joined Kardia's New Donquixote Family. In the 2021 show he took part in Kardia's revenge against the Straw Hat and Heart Pirates, spying alongside Sarutobi and discovering that Tama carried an umbrella made by Portgas D. Ace, which they reported so Kardia could replicate Ace's appearance. When the family ambushed the pirates at a restaurant, Musashi dueled Zoro and was swiftly beaten.
