Melancholy and Whist appear at the POG headquarters to deliver a message from Klondike challenging Kaito to a puzzle, revealing he has Freecell in his possession. As Kaito and Klondike prepare themselves for the puzzle, in which they must design a maze for their opponent and be the first to solve their opponent's maze, Klondike reveals all of his experiments were to create a Final Ring for himself. As Kaito struggles against Klondike's maze, Melancholy reveals her ring is a genuine Orpheus Bangle. As Kaito figures out the nature of Klondike's maze, Klondike activates his Final Ring, absorbing Kaito's brainwaves to complete it.
