In a multiplayer game, if a player controls Dark Imposter that exiled an opponent's Kiki-Jiki, Mirror Breaker, does Dark Imposter still have Kiki-Jiki's ability if Kiki-Jiki's owner leaves the game?
No.
When a player leaves the game, all cards they own leave the game with them, so Kiki-Jiki is no longer exiled with Dark Impostor.
