The Card of Darkness - Hidden Knight Hook.Crow continues to bear the pain of his arm, whilst he avoids Hidden Knight Hook's assaults on his Duel Runner. He eventually manages to destroy it, and knock Hermann out by summoning out his Black-Winged Dragon, but when Hermann tries to revive his Hidden Knight Hook, Crow sacrifices his dragon in order to completely destroy Hidden Knight Hook before it can attack him, and then defeats Hermann. His arm at the peak of his pain, Crow passes the duel on to Jack, who begins the next round against Nicholas. Nicholas uses another Card of Darkness, a trap intended to knock both of them out, however it hurts both of them, as Primo has no more use for Nicholas, and allowed his protection against the Card of Darkness to expire. Jack escapes defeat, thanks to his monster's special ability, and rescues Nicholas before he crashes. With Nicholas' Duel Runner destroyed, Team 5D's automatically qualifies for the quarterfinals. Meanwhile, Primo unleashes his army of Ghosts (collectively known as "The Diablo") throughout the city.
