A tall female student and fellow player in Mocha Forest. She initially shows sympathy toward Ling Mo (alias Sesame Tangyuan), assuming she is destined to lose the game due to low points. Yunyan is resourceful, devising a method to keep wild beasts away by smearing feces around trees. She leads a group of players who band together for safety after having their points stolen. She later becomes curious about Ling Mo's survival abilities and searches for her upstream.
