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 him to dispatch the monsters in order to protect her sheep. After completing the quest, she thanks Link and rewards him with ten Fresh Milk.
