Sebastian, Claude, and Hannah row a boat with Ciel's body to a remote island. Hannah says that both Sebastian and Claude will fight a true Demon's Duel for the right to claim Ciel's soul. After removing the Demon Blade from her body, Hannah places the sword in a cave and the two demon butlers begin their duel. Both butlers take the sword back and forth between them but neither manages to make a fatal blow. Sebastian, feeling confined by the cave, uses the sword to split the island in half creating a large fissure in the ground. In limbo, Ciel and Alois comment on the fight, with Ciel saying Alois doesn't understand Sebastian's motivations. Alois concedes the point, and apologizes for using Ciel for his own purposes. The battle appears to be a stalemate until Claude lands on a rock that gives way under him, causing him to lose his balance. The momentary distraction allows Sebastian to plunge the Demon Blade through Claude's body. Sebastian comments that Alois has been 'playing' with Claude all this time and he never realized it. As he dies, Claude comments that Alois managed to make a 'small ripple' in the long, boring life of a demon, so perhaps Alois's soul was more precious than he thought. Hannah sheds tears of joy and reveals that the contract Alois made with Hannah was to get Claude to acknowledge him. Sebastian comes for Ciel, but Hannah falls to the ocean below with him speaking unheard words that shock Sebastian. He dives in after Ciel and after reaching him, he kills Ciel just as he awakens. Back on the island, Hannah lies down with Claude's body, saying that she, Claude, Alois, and his brother can now all be together. Some time later, Ciel awakens in bed with Sebastian preparing him tea. As Ciel is dressed by Sebastian, his eye takes on a demon glow. It is revealed that as a condition of Alois's wish being fulfilled, Alois asked that Hannah makes Ciel's soul unattainable by either Sebastain or Claude. She did this by causing Ciel to be reborn as a demon. As a result, Sebastian can no longer consume Ciel's soul, but is still bound by their contract. Ciel sends goodbye notes to everyone he knew, dismisses his helpers, and leaves with Sebastian. The final scene has Sebastian carrying Ciel through a field of black and white roses towards a cliff. Ciel says that he feels that a great curse has been lifted from him, with Sebastian responding that in exchange he is 'cursed' to service Ciel forever. Ciel remarks that Sebastian is his butler and wants to only hear one response from him. Sebastian jumps with Ciel from the cliff into the darkness to a place where man and demon are equal, all the while saying, 'Yes, My Lord'.
