Kozuki Denjirou, also known as Kyoshiro, is a samurai from the Wano Country arc in One Piece and one of the loyal retainers of the Kozuki family. He serves as a key supporter of the Kozuki rebellion against the shogunate and Kaido’s forces. Outwardly, he appears as the stern and manipulative yakuza boss Kyoshiro, but in truth he remains devoted to restoring Wano and protecting Momonosuke’s cause. He plays an important strategic and emotional role in the resistance.
