The Tsoi Family was a gang, led by Viktor Tsoi, for whom it is named after, on Coruscant. While attending a private school in Imperial City, Viktor formed an inner circle of three friends, who became his gang. They undertook activities in the Coruscant underworld, often clashing with the Hutt Cartel. In 17 ABY, two of the Family's members got into a situation with the leader of the Black Sun. They were ambushed near their school by Twi'lek gangsters, and Viktor was the only one that escaped alive.
