The young exorcist from Liyue, Chongyun. One might find Chongyun as a composed and stoic individual, though his friends might not say it is true most of the time.

Chongyun is a positive individual quite literally, as he has an excess of positive energy in him. Due to this excess in positive energy, he's vulnerable to things that warms him — fiery events, food, drinks, clothing, the sun, and even blushing. In the event he is not able to suppress those feelings, he might enter a manic state of being excited, friendly or faint. In extreme cases, he may show extreme signs of irrationality. To counter said positive energy, he always wears light-colored and light-weight clothing and usually eats cold food, though even with these methods and despite his efforts, he still has issues overcoming his unusual constitution.

Despite having a Vision, he's not as fond of it as others, believing that training is the way to become a stronger individual. Due to his intense training and the sole focus of exorcising a demon, Chongyun is extremely introverted in everything outside of exorcism.[2] He regards Xingqiu as a friend due to their similar agendas despite being pranked on by the bookworm on a frequent basis, which he usually tolerates.[3] Even beyond Xingqiu's pranks, Chongyun can be quite gullible, such as once taking the contents of a novel to be real-life events until informed otherwise.
