Banda Djetskiy are a Jet-Ski motor gang that terrorizes the communities of Floridian Archipelago, Spanish Coast & Costasore. They are the descendants of Russian expatriate communities living in Florida.
The name is presumably derived from a Russification of the word "Jet-Ski," though the members insist they are a family and it's their surname.
Yes, that's stupid as hell. No, I don't care.
