The Nine Red Scabbards are a squad of nine formidable samurai who served Kozuki Oden.
The captain of the Nine Scabbards is Kin’emon, a powerful swordsman with the ability to cut fire, that even the current leader of Wano Country’s Yakuza, Kyoshiro, showed interest in fighting against.
20 years ago during the Beasts Pirates takeover of Wano Country, they were supposedly taken down by the Shogun Kurozumi Orochi for the family’s plan to open up the boarders of Wano. Despite their defeat, it was prophesied by Kozuki Toki that they will return 20 years later to claim their vengeance.
In truth, Toki used her Toki Toki no Mi abilities to send Kin’emon, Kanjuro, Raizo, and Kiku to the designated period, ensuring at least four members of the group would resurface.
Meanwhile, Kawamatsu was entrusted with the protection of Hiyori while waiting for his allies to return. 13 years ago, however, Kawamatsu and Hiyori were separated, with the former being imprisoned in the Udon Prisoner Mines, forced to only eat poisoned fish.
In Chapter 943, a flashback is shown with the Nine Red Scabbards in their youth and their loyalty to Oden.
The group includes Kin’emon, Raizo, Kanjuro, Kiku, Kawamatsu, Ashura Doji, Inuarashi and Nekomamushi. The last member, Denjiro, has yet to reveal himself.
