Fiona Wu

Fiona Wu is a young, East Asian cybersecurity troubleshooter working for HSMBC. She was onboard HSM Hadley's Hope, and oversaw the retrieval of the damage R'lyeh Dataserver in January 2049. However, she failed to notice Doll's tampering on the server due to a distraction orchestrated by Light and BYTE.
Later in February, her matrix persona, a kigurumi wearing anime character, was observed conducting an sysop patrol in the NUH mainframe, while Doll was conducting another operation in the hospital. She manage to identify Doll just as the latter manages to jack out of the system and make good her escape.
