Pendant of Memories

The Pendant of Memories is an item in Majora's Mask. It is a small charm that Kafei wears around his neck. When Link meets Kafei for the first time during the Second Day, Kafei gives Link the pendant after explaining what happened to him and asks the young hero to give it to Anju. Upon receiving it, Anju will promise to wait for Kafei until he returns, heavily implying the sentimental value of the pendant.

If, however, Link fails to deliver the Pendant of Memories to Anju, but continues to help Kafei retrieve the Sun Mask from Sakon's Hideout, Kafei will arrive to the Stock Pot Inn without Anju being there, blaming himself for not being able to keep his promise despite the fact that it is clearly the fault of Link for not delivering it.

The charm has no real use while in Link's inventory, but it's symbolic of the love Kafei and Anju share.
