Shih-na is Lang's closest subordinate, following him in his investigations and fetching various documents for him. In reality, "Shih-na" is merely a cover for an anonymous spy and skilled defense attorney working for the Cohdopian smuggling ring, who previously went by the alias "Calisto Yew". As her job required her to change her personality and appearance, it is unclear what of Calisto/Shih-na was real and what was fake. She's prone to fits of uncontrollable laughter at inappropriate times.
