Xiao

Xiao has medium-length dark hair with teal undertones, pale skin, and golden cat eyes. On her forehead is a small purple diamond, and her eyes have red makeup similar to that of Zhongli and the Cloud Preserver. Xiao also has a green tattoo around her right arm.

Xiao wears a white sleeveless shirt with a black collar, dark purple pants, and dark purple boots. She wears black and dark turquoise gloves with gold decals and a necklace. Around her left arm, Xiao wears a white and gold sleeve with a red lining. In particular, she wears an Anemo Vision on her left glove and is usually seen with her Yaksha mask on the back of her right hip, measuring 1.58cm, she is about 2,000 years old.

Xiao is quite polite, reserved and logical, although brief and to the point. as he is shown to remain calm and reconsider his actions upon learning of Rex Lapis' death. While other Adeptus chose to abandon their duties to protect the people of Liyue. When they learned of Rex Lapis' murder, Xiao prioritizes his duty and tries to find more information about Rex Lapis' death, instead of acting recklessly like the other Adeptus.

He is rarely in a good mood and prefers to be alone. He shows almost no interest in humans and their culture, some of which he finds strange or useless. However, there are some people he finds notable, such as Hu Tao for her "interesting" (but "irritating") humor and Beidou for defeating a leviathan by herself. Xiao maintains a distant and cold approach, but actually cares about Traveler, as his lines show that he secretly cares.

Xiao is also revealed to be a strict but effective teacher, especially as he is a mentor figure to Ganyu. While Ganyu finds Xiao to be a reclusive and somewhat unapproachable person at first, he admits that he is an important part of her reaching her full potential as an adept. Chongyun comments that he has a deep admiration for Xiao and his demon-conquering abilities, but at the same time points out his disparaging comments about the exorcists' methods. At the same time, Xiao says not to judge Adeptus according to mortal values, flirtatious, charismatic, protective, somewhat jealous, daring, dominant.
