Koyin is a character from The Legend of Zelda: Breath of the Wild. She is a Hylian farmer living in Hateno Village, located in the East Necluda region of Hyrule, on a farm with Dantz. While Dantz is concerned with the growing deer population in the nearby woods, Koyin is frustrated with the monsters residing at Hateno Beach who have been stealing her sheep. She posted a flyer on one of the notice boards in the village seeking for help. She offers to Link the "The Sheep Rustlers" side quest asking for dispatching the monsters in order to protect her sheep. After completing the quest, she thanks Link and resumes her life as a farmer raising her livestock.
