Caitou is an extremely big person with a height exceeding 2m, wide shoulders and tanned skin. He is bald headed and has a dark complexion.
Caitou is a very kind and honest person. He is straight forward and does not look down on others despite them weak, strong or otherwise. He is very easy going.
Caitou meets with Huo Yuhao at the Spirit Guidance Testing Area where he is asked by Fan Yu to fire a Mounted Spirit Guidance Weapon with the help of Yuhao. He gives Yuhao a basic introduction about Spirit Guidance Weapons and wishes he will become his junior very soon by joining the Spirit Guidance Department.
