The Master Sword (originally from Zelda) is a legendary sacred sword that was used by the Legendary Hero to defeat Ganondorf ages ago. The sword took the form of a Yield sign, which has converted into a staff for the KND to use. Generations of KND leaders have passed the staff onto the next, so that one day, the Hero's descendant would hold the sword. This descendant turned out to be Numbuh 362, and Clockwork revealed the staff's true form in Legend of the Eight Firstborn. Rachel now wields the Master Sword. The sword has a guardian spirit named Fi.
