Ximing is Liu Xuelan's butler and a member of the Sunset Ravens clan. He possesses light-colored hair and a mustache, usually attired in formal suits and ties, though he sometimes dons traditional Chinese garments. After a significant timeskip, his appearance remains largely unchanged except for acquiring a prosthetic leg below the left knee, requiring him to use a cane for mobility.

Demonstrating unwavering loyalty to Xuelan, he faithfully executes her instructions. However, he does voice dissent when necessary, such as successfully convincing her to acknowledge defeat based on pre-agreed battle conditions. He expresses satisfaction when encountering capable fighters within Japan. Considering himself a guest within the Sunset Ravens, he generally refrains from offering unsolicited opinions.

While his specific Sigil ability remains undisclosed, his participation in Darwin's Game confirms he possesses one. Ximing is a highly proficient combatant, skilled enough to serve as an instructor for Sunset Ravens members like Sudou Kaname, Ouji Kimihiko, and Inukai. His martial prowess commands caution even from formidable opponents like Long Tao and his subordinates.
