Kafei

In Majora's Mask, Kafei is a young man who lives in Clock Town. He is the son of Mayor Dotour and Madame Aroma, and he is engaged to Anju, the inn-keeper at the Stock Pot Inn. Although the two lovers made a promise to exchange the masks of the sun and the moon and get married on the day of the Carnival of Time, a sudden turn of events forces Kafei to run from Anju's side, leaving the young inn-keeper without a reason for his immediate departure. It is up to Link to reunite Anju and Kafei and help them keep the promise they made to each other so many years ago.

Kafei is renowned as being the first playable character in the Legend of Zelda canon series that is not Link.

Biography
Kafei is one of the twenty characters in the game with an entry in the Bombers' Notebook, and all of his entries are related to the "reuniting Kafei and Anju" sidequest, in which he plays a key role.

When Kafei and Anju were children, they promised each other to marry on the day of the Carnival of Time, exchanging the masks of the sun and the moon during the event; however, Kafei was suddenly turned into a child by the Skull Kid. On his way to see the North Clock Town Great Fairy about his desperate situation, Sakon came along and stole his wedding ceremony mask. As such, Kafei could not return to Anju despite knowing that she was worried, for he had promised her to greet her with his wedding mask in hand. He goes into hiding at the Curiosity Shop and disguises himself with a Keaton Mask that the Curiosity Shop owner gave him when he was a child, secretly watching all of the customers of the Curiosity Shop (which sells stolen goods). He is positive that the thief will appear and he will be able to follow him to retrieve his mask. Despite Kafei's terrible fate, Anju does not know what has become of him or why he disappeared. She is afraid to meet his fiance and hear the reason as to why he escaped, for she fears his disappearance might have been caused by her.

When Link intervenes to help reunite Kafei and Anju, he gets a chance to meet Kafei after he witnesses the delivery of the letter he deposited in the mailbox as requested by Anju. Kafei explains to the young hero his reasons for his disappearance and why he can't go see his fiance, and asks Link to deliver his pendant to Anju as proof that is still willing to keep his promise. Once the young inn-keeper receives this extremely important item, she will once again believe in Kafei and decide to wait for his return despite that everyone else will be taking refuge in Romani Ranch.

On the night of the Final Day, Link and Kafei team up to enter Sakon's Hideout and retrieve the Sun Mask in the process. After making their way through the trap-filled hideout, Kafei recovers the wedding mask and immediately leaves for the Stock Pot Inn to meet up with Anju. With just a few hours left until the moon falls, Anju is desperately waiting for Kafei in her room with her Moon Mask. The two lovers at last reunite and exchange their masks and oaths when Kafei finally arrives with his mask. In return for witnessing this event, they grant Link the Couple's Mask. Even though the moon is just hours from destroying Termina, they urge Link to take refuge, for they will stay and greet the morning together.

During the ending credits, Anju and Kafei can be seen outside of Clock Town having their wedding ceremony. Kafei is never specifically shown in this scene, but it is assumed he was turned back into an adult since the camera is put into Kafei's point of view, and he is looking straight at Anju's face.

Sun Mask
The Sun Mask is the mask that Kafei gives to Anju as a part of their wedding ceremony. Sakon the thief stole it and took it to his hideout in Ikana Canyon. Once Link and Kafei retrieve it during the night of the Final Day, they take the mask to Anju, who is waiting patiently on the second floor of Stock Pot Inn. Accompanying the Sun Mask is a silver mask, the Moon Mask.

Pendant of Memories
The Pendant of Memories is a small charm that Kafei wears around his neck. When Link gives it to Anju, she will promise to wait for Kafei until he returns, heavily implying the sentimental value of the pendant.

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

Animal Crossing
In Animal Crossing for the Nintendo GameCube, Kafei's clothes appear as an item that players can purchase and wear as the item "Kafei's Shirt".

Super Smash Bros. Brawl
Kafei appears as a sticker in Super Smash Bros. Brawl.
