Chen Yao operates as the steadfast right-hand man to Liu Xiao, leader of Shanghai's Longhu-bang criminal organization, which dominates human trafficking operations. He supports Liu in running a Shanghai dummy corporation formerly tied to Akemi Suzaku's ventures. Chen sports a mix of blonde and brown hair, brown eyes, a chin strap beard, and a penciled-in mustache, with an unmistakable upside-down L-shaped scar on his left cheek. His signature style includes a gold chain, a salmon-colored jacket, black pants, and forest green shoes.

Tactless and quick to flare into anger, Chen Yao intensely resents any perceived disrespect yet exhibits unshakable loyalty to Liu Xiao, whom he reveres. His core responsibilities involve enforcing the gang's activities and securing their grip on human trafficking networks.
