Shih-na

Shih-na is an Interpol agent acting as a secretary in Gyakuten Kenji. She accompanies Shi-Long Lang in most of his encounters with Miles Edgeworth.

Personality
Shih-na always acts alongside Lang, with an ability to stay calm during all investigations. Lang and Shih-na have a strong bond of trust. Shih-na's devotion to Shi-Long Lang is similar to that of Viola Cadaverini towards Furio Tigre. She barely speaks unless she is properly addressed and during GK-5 when confronted by Miles Edgeworth she eventually breaks out in a familiar fit of laughter that both Miles Edgeworth and Franziska von Karma remember.

Spoilers Below:
Shih-na is in actuality, Calisto Yew, the defense attorney from GK-4. She is a spy that takes orders from Quercus Alba, the head of the smuggling ring that Lang has been pursuing due to their involvement with counterfeit bills ruining the economy in Zheng-Fa.

Name
The Japanese name is written with katakana characters, so she may be non-Japanese. However, Shih-na is not her true name.

Turnabout Ablaze
During the initial investigation during Turnabout Ablaze she was about to arrest Kay Faraday for the murder of Manny Coachen, however Kay was soon cleared by Miles Edgeworth. Later on Shih-na was soon suspected for the murder herself as her movements before her apprehension of Kay Faraday came into question. During her questioning, she soon was discovered as actually being Calisto Yew, from Turnabout Reminesence. She also revealed herself as part of the smuggling ring sent to spy on Interpol through Agent Shi-Long Lang. Afterwards she angered Kay to cause her to get closer and Yew was able to use her as a hostage in an attempt to escape. However, Detective Badd appeared and was about to shoot her to prevent this but she was saved by Agent Shi-Long Lang and was brought into custody. But before she was taken in, she revealed that she was not the true killer of Manny Coachen, presenting a problem with the investigation.
