Kafei appears in the Legend of Zelda: Majora's Mask, he is the first playable secondary character in the Zelda game series.
Kafei is a young man who resides in Clock Town, his father (Mayor Dotour) is the mayor. He's engaged to be married to Anju, an innkeeper in the town. Kafei's quest is the longest in the game, spanning all three days and involving several masks.
And speaking of masks, this Kafei papercraft comes with a Keaton's Mask (the one he gets from the Curiosity Shop owner), as of this post the links are not up yet, the designer requests that you share your opinion about the model, so start commenting ^_^
