Chongyun is a positive and honorable young man with a passion for sweets. He takes his duties as an exorcist seriously and usually has a stoic, composed personality, although this isn't always the case. Chongyun can be quite gullible. He has light blue hair reaching his ears, pale skin, and ice-blue cat slit eyes. He is 16 years old. He gets hot easily and constantly needs to cool his body down.
