Kenji Kasen

Kenji wants the Yardies wiped out for muscling into Yakuza turf. Claude hunts Yardie crews across Staunton Island until every last one of them is gone.
Smack Down is the final mission in Grand Theft Auto III given to protagonist Claude by Yakuza co-leader Kenji Kasen from his casino in the Torrington district of Staunton Island, Liberty City.
Kenji is furious in finding out that, even after the Yardies are framed for the murder of numerous Colombians, they are still able to convince the Cartel to ally with them. Kenji dispatches Claude to kill as many Yardie SPANK pushers as he can find.
