Rook informs Kaito that Jin had previously made some Fool's Puzzles, which he himself destroyed as a means to improve his Giver skills, theorising that he may have been under influence from the Orpheus Bracelet. Kaito, refusing to acknowledge this, shows Jin a warm puzzle he once showed him during his childhood. Meanwhile, Freecell falls into a trap laid out by Melancholy, who has joined the Master Brains in order to get revenge on him, trapping him in an underground maze. Learning of Freecell's predicament from Pinochle, Kaito, Nonoha, and Gammon fly to England to search for him, finding him at an old train yard, where Melancholy challenges Kaito, Gammon and Freecell to a Fool's Puzzle, in which they must connect with their partners whilst sacrificing the other players. Contrary to her expectations, however, Melancholy is chosen as the fourth player in the game by Enigma, who had caught onto her intention to try and save the others and also claims it to be a puzzle built by Jin. As Gammon notices a message laid out by Kaito, both Freecell and Melancholy struggle with theirs.
