Hibiki Fuka (響き不可) is the famed Kunoichi of Otogakure, the Village Hidden in Sound. Headship of the weapons line Echo, and the leading hand in Fuinjutsu and Bukijutsu, Hibiki has gained the eyes and ears of those in the lands. With sponsorship, the Cannon of Oto now owns the world's finest special weapons. Once a rough street urchin, raised for civil war, now the very embodiment of success; hard work bloomed into reward.
