An Ran is a senior student of the Northern Heavens Spiritual Academy. When the freshmen, of which Mu Chen was a member, were joining the Northern Heavens Spiritual Academy, she was a part of the bonus testing round, whereby she ended up being pitted against Mu Chen. With her personality of only respecting the strong, she looked down upon him, but when he beat her, she began to respect him.
Later, during the Academy's Hunting War, she found herself surrounded. Due to her weak strength, her team was being bullied and they were about to be extorted. However, she was saved by Mu Chen and Luo Li and subsequently travelled with them until they reached Spiritual Light Mountain.
