Oniruko was a female pirate and slicer who lived on Tatooine during the Galactic Civil War. After the Battle of Yavin, Oniruko was part of a pirate gang led by Eyan McDermitt. In 1 ABY, the gang hijacked a courier ship belonging to the Incom Corporation. The pirates were only after general cargo but they also stole an encrypted datapad with sensitive information. Oniruko attempted to slice but she was severely shocked by the storage device's protection system, starting foaming at the mouth and convulsing. Unfortunately, her pirate fellows were not able to get her to the medical center in time. Since he did not succeed in obtaining the data, Eyan McDermitt later accepted to sell the datapad to an Imperial commando named Jubai Laetlii. The datapad was eventually retrieved by a spy working for Sarlis Beni and returned to Incom Corporation.
Oniruko was mentioned in the 2003 video game Star Wars Galaxies, a massively multiplayer online roleplaying game developed by Sony Online Entertainment and published by LucasArts, prior to its closure on December 15, 2011. Mntion of Oniruko was added to the game upon the release of the "Publish 25," a.k.a. the "New Game Enhancements," on November 15, 2005.
