"Foxfire Kin'emon" is a samurai from Wano Country, a retainer of the Kozuki Family, the leader of the Nine Red Scabbards, the husband of Tsuru, and a former thug. He was born 56 years before the present day, but traveled 20 years forward in time when he was 36 years old. Due to Wano Country having been taken over by Kurozumi Orochi, an ally of Kaido of the Four Emperors, Kin'emon set out on a seafaring quest to recruit warriors for his cause, bringing alongside him his master, Kozuki Momonosuke, as well as two of his comrades. After a series of misadventures, Kin'emon ended up on the island of Punk Hazard, where he met and joined forces with the Straw Hat Pirates, posing as Momonosuke's father during the journey to Zou. He is one of the central allies of the Straw Hats during the Dressrosa and Four Emperors Sagas.
