Biography
Koyin works on a farm below the Hateno Ancient Tech Lab in Hateno Village, tending to animals such as Hylian sheep and cows with Dantz. When Link first meets her, she is angrily talking to herself and holding a stick in her hand.

Should Link decide to speak to her in spite of her sour attitude, she is immediately aggressive toward him. However, she eases up a bit to explain her situation. According to Koyin, a group of monsters have been abducting her flock. This unlocks the quest "The Sheep Rustlers".

Koyin goes on to explain how she had driven off the monsters at another time, but is not certain enough of her ability to handle them all at once in their own territory. If Link asks her about Hateno Beach, she will tell him where to go. Once Link tells her goodbye, Koyin sighs and apologizes for being defensive. Until the quest is completed, Koyin is too concerned about the herd to go to sleep. She will stay up throughout the entire night to watch after them. Even the rain is not enough to budge her from her spot.

She gives Link the quest "The Sheep Rustlers", telling him that several monsters have been stealing and riling up her sheep, asking him to take care of them. Upon completing the quest and speaking to her, she rewards Link with 10 bottles of Fresh Milk.
