Yojimbo is acquired by visiting the Cavern of the Stolen Fayth, where the player must hire him to become Yuna's aeon. Yojimbo acts as a sword-for-hire and has four different attacks depending on how much the player pays him, as well as a complex mathematical formula based on his worker-employer relationship with Yuna and several other factors. Yojimbo functions similarly to Odin and Gilgamesh from previous Final Fantasy games. His most powerful attack, Zanmato, instantly kills fiends and bosses.
